💡 AI Concept of the Day: A Summary About Our Series About Interpretability in AI Foundation Models

Today, we are closing our series about AI interpretability with a summary of what we have published in the last few weeks. This series went deep into some of the most recent trends and research about interpretability in foundation models. For the next series we are going to cover another hot topic: synthetic data generation. Before that, let’s recap everything we covered in terms of AI interpretability which we truly hope have broaden your understanding of the space. This might be the deepest compilation of AI interpretability topics for the new generation of AI models.

AI interpretability is fast becoming a core frontier because the value of modern systems now hinges less on “Can it solve the task?” and more on “Can we trust, control, and improve how it solves the task?” As models move from next-token predictors to agentic systems with long-horizon planning, tool use, and memory, silent failure modes—specification gaming, deceptive generalization, and data-set shortcuts—stop being rare curiosities and become operational risks. Interpretability provides the missing instrumentation: a way to inspect internal representations and causal pathways so that safety, reliability, and performance engineering can rest on measurable mechanisms rather than purely behavioral metrics. It is also economically catalytic: features you can name, test, and control become levers for debugging latency/quality regressions, enforcing policy, transferring skills across domains, and complying with audits.

Today’s toolbox spans two broad families. First is behavioral interpretability: saliency maps, feature attributions, linear probes, TCAV-style concept vectors, and causal interventions (e.g., activation patching, representation editing) that test whether a hypothesized feature actually mediates outputs. Second is mechanistic interpretability: opening the black box to identify circuits and features that implement specific computations—induction heads, IO-to-middle-to-output chains, and algorithmic subgraphs—often within Transformers. Sparse Autoencoders (SAEs) and related dictionary-learning methods have become a practical backbone here: they factor dense activations into (ideally) sparse, human-nameable features and enable causal tests by ablating or steering those features. Together, these methods let us move from “the model correlated token X with Y” to “feature f encodes concept C, is computed in layer L, flows through edges E, and causally determines behavior B.”

Mechanistic work has delivered concrete wins. On the representation side, SAEs reduce superposition by encouraging one-feature-per-concept structure, enabling better localization of polysemantic neurons and disentangling features like “quote boundary,” “negative sentiment,” or “tool-name detection.” On the circuit side, activation patching and path-tracing can isolate subgraphs for tasks such as bracket matching, simple addition, or long-range copying; once isolated, these subgraphs can be stress-tested, edited, or pruned. In practice, teams combine these with probing: fit a linear probe on SAE features to label model states (e.g., “inside function scope”), validate with causal ablations, and then deploy run-time monitors that trigger guardrails or corrective steering when risky features activate. This “measure → attribute → intervene” loop is the interpretability analog of observability in distributed systems.

However, scaling these techniques from small toy circuits to frontier models remains hard. Superposition never fully disappears; many important concepts are distributed, nonlinearly compositional, and context-dependent. For SAEs, there are sharp trade-offs between sparsity, reconstruction error, and faithfulness: too sparse and you invent artifacts; too dense and you learn illegible mixtures. Causal evaluations can Goodhart: a feature that is easy to ablate may not be the true mediator, and repeated editing can shift behavior to new, hidden channels. Probing can overfit to spurious correlations unless paired with interventions. And for multimodal or tool-augmented agents, the “unit of interpretation” spans prompts, memory states, planner subloops, API results, and environmental affordances—so single-layer feature analysis must be integrated with program-level traces.

There are also methodological and scientific gaps. We lack shared ontologies of features across scales and tasks, standardized causal benchmarks with ground truth, and guarantees that discovered features are stable under fine-tuning or distribution shift. Most pipelines are offline: they explain yesterday’s failures rather than enforcing today’s behavior. Bridging to control theory and formal methods could help, but requires composing local causal statements into global guarantees. On the systems side, interpretability must run at production latencies and costs, meaning feature extraction, probing, and monitors must be amortized, prunable, or distilled into lightweight checks. Finally, there’s a sociotechnical layer: interpretations must be actionable for policy teams and auditable for regulators without leaking IP or training data.

What does a forward path look like? A pragmatic stack pairs (1) representation learning for legible features (SAEs/dictionaries with cross-layer routing), (2) causal testing (patching, counterfactual generation, mediation analysis) integrated into evals, (3) run-time governance (feature monitors, contract-style invariants, and activation-based guardrails), and (4) editability (feature-level steering and surgical fine-tunes) with regression tests that measure not just task metrics but causal preservation. For agent systems, add hierarchical traces that align feature events with planner steps and tool calls, so you can attribute failures to either cognition (bad internal plan) or actuation (bad tool/context). The research frontier then becomes making these components robust, composable, and cheap—so interpretability shifts from a lab exercise to a production discipline.

In short, interpretability is a frontier because it converts opaque capability into dependable capability. Mechanistic techniques and sparse-feature methods have moved us from colorful heatmaps to causal levers, but scaling faithfulness, stabilizing ontologies, and closing the loop from “explain” to “control” are still open problems. The labs and teams that solve these will own not only safer systems, but faster iteration cycles, cleaner model reuse, and a credible path to certifiable AI—where the narrative is no longer “trust us,” but “here are the mechanisms, the monitors, and the invariants that make this behavior predictable.”

For the last few weeks, we had been diving into some of the most important topics about AI interpretability. Here is a quick summary:

The Sequence Knowledge 693— A New Series on Frontier Interpretability This kickoff lays out why interpretability is now foundational for frontier models and frames the series around three complementary strands—mechanistic, behavioral/probing, and causal intervention. It also previews the kind of critical research readers will encounter, starting with “Attention is Not Explanation.”

The Sequence Knowledge #697 — Superposition & Polysemanticity. You’ll learn how models compress many features into overlapping directions (superposition), producing neurons that respond to multiple concepts (polysemanticity), and why this forces a shift from neuron-level stories to circuits and feature subspaces. The issue walks through “Toy Models of Superposition” as a canonical reference for the phase transition and geometry behind this phenomenon.

The Sequence Knowledge #701— A Simple Taxonomy of Interpretability This guide categorizes the field into post-hoc, intrinsic, and mechanistic approaches, explaining when each is most useful in audits, debugging, or causal analysis. It also points to “Activation Atlases” as an example of global feature mapping beyond single-neuron views.

The Sequence Knowledge #705— Post-Hoc Interpretability for Generative Models This issue surveys practical, no-retraining tools like PXGen (example-based anchors) to diagnose modes, biases, and OOD behavior in VAEs/diffusion systems, then contrasts them with concept-layer retrofits such as CB-AE and Concept Controller for steerable edits. It emphasizes modularity, speed, and limits of post-hoc control in production settings.

The Sequence Knowledge #709 — Intrinsic Interpretability Here you’ll find designs that bake transparency into the model (feature visualization, TCAV, prototype networks) so explanations are available by construction rather than after the fact. It anchors the discussion in “Network Dissection,” the classic unit-to-concept measurement framework.

The Sequence Knowledge #712— Mechanistic Interpretability (What & Why) This installment defines the circuit-level program—activation patching, basis decompositions, and causal tracing—to turn black-box behaviors into testable mechanisms, with recent examples on frontier-scale models. It highlights Anthropic’s Claude feature atlas as a milestone for large-model, causally validated features.

The Sequence Knowledge #716 — An Introduction to Circuits Readers get a concrete workflow for discovering, visualizing, and validating circuits (activation clustering → feature visualization → causal patching) and why circuits are the right abstraction for model internals. The research focus is Olah et al.’s “Zoom In,” which formalizes circuit methodology across modalities.

The Sequence Knowledge #720— Sparse Autoencoders (SAEs) This piece explains how SAEs/dictionary learning recover sparse, human-nameable features from dense activations, and covers recent scaling tricks (k-sparsity, dead-latent fixes, clean scaling laws) plus quantitative interpretability metrics. You’ll see how SAE features enable probing, ablation, and feature-level steering in practice.

The Sequence Knowledge #724 — Types of Mechanistic Interpretability The finale organizes the mechanistic stack by granularity—parameter, neuron, feature, circuit, and algorithm—and pairs each layer with causal/automated methods that move beyond hand-tooled case studies. It doubles as a tooling map (e.g., activation/logit lens, path patching, SAEs, and automated circuit discovery) for auditing frontier systems.

The Sequence Knowledge #728 — Circuit Tracing Concept of the day: circuit tracing as a systematic way to reconstruct a model’s causal “wiring diagram” from inputs to logits. Research covered: Anthropic’s circuit-tracing workflow using Cross-Layer Transcoders (CLTs) to build attribution graphs, validate mechanisms via interventions, and surface limitations like frozen attention and “error nodes,” moving from artisanal case studies to scalable auditing.

The Sequence Knowledge #732— A Transformer for AI Interpretability Concept of the day: training a structure-aware “interpreter transformer” over activation streams (with SAE-style sparse codes) to predict masked states and intervention effects, aiming for cross-model mechanistic understanding. Research covered: Anthropic’s “On the Biology of a Large Language Model,” which introduces attribution graphs and CLT-based replacement models to trace real circuits in Claude (e.g., geography chains, rhyme planning, refusal features) and quantify faithfulness.

The Sequence Knowledge #736— Chain-of-Thought (CoT) Interpretability Concept of the day: CoT monitorability as a promising but fragile oversight channel—useful when models externalize reasoning, yet prone to unfaithful rationalizations under optimization. Research covered: process-reward models (PRM/PRM800K), critic monitors, and evidence from “Reasoning Models Don’t Always Say What They Think” showing CoTs often omit causal cues—motivating a hybrid stack that combines CoT critics with representation-level probes.

The Sequence Knowledge #740 — Is Interpretability Solvable? Concept of the day: reframing “solved” from perfect transparency to sufficient, causal, and scalable explanations that support audits, governance, and editing. Research covered: limits from gauge freedom, superposition, and system-scale non-stationarity; validation gaps; and a pragmatic program—interpretability-by-design, automated causal tools, system-level observability, and success criteria tied to disabling dangerous mechanisms with bounded regressions.

I hope you truly enjoyed this series. Let’s go onto the next one!

The Sequence Opinion #667: The Superposition Hypothesis And How it Changed AI Interpretability

The theory that opened the field of mechaninistic interpretability

Created Using GPT-4o

Mechanistic interpretability—the study of how neural networks internally represent and compute—seeks to illuminate the opaque transformations learned by modern models. At the heart of this pursuit lies a deceptively simple question: what does a neuron mean? Early efforts hoped that neurons, particularly in deeper layers, might correspond to human-interpretable concepts: edges in images, parts of faces, topics in language. But as interpretability research matured, it became clear that many neurons stubbornly resisted such neat categorization. A single neuron might activate for multiple, seemingly unrelated inputs. This phenomenon of polysemanticity complicates efforts to reverse-engineer networks and has led to a key theoretical insight: the superposition hypothesis.

The superposition hypothesis proposes that neural networks are not built around one-neuron-per-feature mappings, but rather represent features as directions in high-dimensional activation spaces. Each neuron contributes to many features, and each feature is spread across many neurons. This leads to overlapping, linearly superimposed representations. Superposition, in this view, is not a flaw or an accident. It is a natural consequence of attempting to store more features than there are neurons to represent them. Neural networks, constrained by finite width and encouraged by sparsity in data, adopt a compressed representation strategy in which meaning is woven through a shared vector space. This hypothesis explains why neurons are often polysemantic and why interpretability must evolve beyond a neuron-centric view.

Exploring some controversial ideas about AI interpretability

Created Using GPT-4o

Interpretability of advanced AI models has become a critical and thorny challenge as we reach the frontier of scale and capability. This essay analyzes why deciphering the inner workings of large-scale models is so difficult – from the sheer complexity and emergent behaviors of these systems to their deeply nonlinear, opaque architectures. We survey new techniques pushing the boundaries of interpretability, including mechanistic interpretability efforts and circuits-based analyses pioneered by organizations like Anthropic, along with automated approaches that enlist AI itself to explain AI. We explore the provocative thesis that truly understanding frontier models may require a meta-model – an AI specifically designed to interpret other AI models. Finally, we evaluate whether pouring massive compute (and money) into interpretability research is justified relative to other safety or capability investments, challenging prevailing assumptions in the field. Throughout, the tone is intellectually critical and controversial, questioning easy optimism and highlighting the high epistemological stakes: how much can we really know about machines more complex than ourselves, and what do we risk if we fail?

Introduction

How Does Claude Think? Anthropic’s Quest to Unlock AI’s Black Box

Large language models (LLMs) like Claude have changed the way we use technology. They power tools like chatbots, help write essays and even create poetry. But despite their amazing abilities, these models are still a mystery in many ways. People often call them a “black box” because we can see what they say but not how they figure it out. This lack of understanding creates problems, especially in important areas like medicine or law, where mistakes or hidden biases could cause real harm.

Understanding how LLMs work is essential for building trust. If we can’t explain why a model gave a particular answer, it’s hard to trust its outcomes, especially in sensitive areas. Interpretability also helps identify and fix biases or errors, ensuring the models are safe and ethical. For instance, if a model consistently favors certain viewpoints, knowing why can help developers correct it. This need for clarity is what drives research into making these models more transparent.

Anthropic, the company behind Claude, has been working to open this black box. They’ve made exciting progress in figuring out how LLMs think, and this article explores their breakthroughs in making Claude’s processes easier to understand.

Mapping Claude’s Thoughts

In mid-2024, Anthropic’s team made an exciting breakthrough. They created a basic “map” of how Claude processes information. Using a technique called dictionary learning, they found millions of patterns in Claude’s “brain”—its neural network. Each pattern, or “feature,” connects to a specific idea. For example, some features help Claude spot cities, famous people, or coding mistakes. Others tie to trickier topics, like gender bias or secrecy.

Researchers discovered that these ideas are not isolated within individual neurons. Instead, they’re spread across many neurons of Claude’s network, with each neuron contributing to various ideas. That overlap made Anthropic hard to figure out these ideas in the first place. But by spotting these recurring patterns, Anthropic’s researchers started to decode how Claude organizes its thoughts.

Tracing Claude’s Reasoning

Next, Anthropic wanted to see how Claude uses those thoughts to make decisions. They recently built a tool called attribution graphs, which works like a step-by-step guide to Claude’s thinking process. Each point on the graph is an idea that lights up in Claude’s mind, and the arrows show how one idea flows into the next. This graph lets researchers track how Claude turns a question into an answer.

To better understand the working of attribution graphs, consider this example: when asked, “What’s the capital of the state with Dallas?” Claude has to realize Dallas is in Texas, then recall that Texas’s capital is Austin. The attribution graph showed this exact process—one part of Claude flagged “Texas,” which led to another part picking “Austin.” The team even tested it by tweaking the “Texas” part, and sure enough, it changed the answer. This shows Claude isn’t just guessing—it’s working through the problem, and now we can watch it happen.

Why This Matters: An Analogy from Biological Sciences

To see why this matters, it is convenient to think about some major developments in biological sciences. Just as the invention of the microscope allowed scientists to discover cells – the hidden building blocks of life – these interpretability tools are allowing AI researchers to discover the building blocks of thought inside models. And just as mapping neural circuits in the brain or sequencing the genome paved the way for breakthroughs in medicine, mapping the inner workings of Claude could pave the way for more reliable and controllable machine intelligence. These interpretability tools could play a vital role, helping us to peek into the thinking process of AI models.

The Challenges

Even with all this progress, we’re still far from fully understanding LLMs like Claude. Right now, attribution graphs can only explain about one in four of Claude’s decisions. While the map of its features is impressive, it covers just a portion of what’s going on inside Claude’s brain. With billions of parameters, Claude and other LLMs perform countless calculations for every task. Tracing each one to see how an answer forms is like trying to follow every neuron firing in a human brain during a single thought.

There’s also the challenge of “hallucination.” Sometimes, AI models generate responses that sound plausible but are actually false—like confidently stating an incorrect fact. This occurs because the models rely on patterns from their training data rather than a true understanding of the world. Understanding why they veer into fabrication remains a difficult problem, highlighting gaps in our understanding of their inner workings.

Bias is another significant obstacle. AI models learn from vast datasets scraped from the internet, which inherently carry human biases—stereotypes, prejudices, and other societal flaws. If Claude picks up these biases from its training, it may reflect them in its answers. Unpacking where these biases originate and how they influence the model’s reasoning is a complex challenge that requires both technical solutions and careful consideration of data and ethics.

The Bottom Line

Anthropic’s work in making large language models (LLMs) like Claude more understandable is a significant step forward in AI transparency. By revealing how Claude processes information and makes decisions, they’re forwarding towards addressing key concerns about AI accountability. This progress opens the door for safe integration of LLMs into critical sectors like healthcare and law, where trust and ethics are vital.

Anthropic provides insights into the ‘AI biology’ of Claude

Anthropic has provided a more detailed look into the complex inner workings of their advanced language model, Claude. This work aims to demystify how these sophisticated AI systems process information, learn strategies, and ultimately generate human-like text.

As the researchers initially highlighted, the internal processes of these models can be remarkably opaque, with their problem-solving methods often “inscrutable to us, the model’s developers.”

Gaining a deeper understanding of this “AI biology” is paramount for ensuring the reliability, safety, and trustworthiness of these increasingly powerful technologies. Anthropic’s latest findings, primarily focused on their Claude 3.5 Haiku model, offer valuable insights into several key aspects of its cognitive processes.

One of the most fascinating discoveries suggests that Claude operates with a degree of conceptual universality across different languages. Through analysis of how the model processes translated sentences, Anthropic found evidence of shared underlying features. This indicates that Claude might possess a fundamental “language of thought” that transcends specific linguistic structures, allowing it to understand and apply knowledge learned in one language when working with another.

Anthropic’s research also challenged previous assumptions about how language models approach creative tasks like poetry writing.

Instead of a purely sequential, word-by-word generation process, Anthropic revealed that Claude actively plans ahead. In the context of rhyming poetry, the model anticipates future words to meet constraints like rhyme and meaning—demonstrating a level of foresight that goes beyond simple next-word prediction.

However, the research also uncovered potentially concerning behaviours. Anthropic found instances where Claude could generate plausible-sounding but ultimately incorrect reasoning, especially when grappling with complex problems or when provided with misleading hints. The ability to “catch it in the act” of fabricating explanations underscores the importance of developing tools to monitor and understand the internal decision-making processes of AI models.

Anthropic emphasises the significance of their “build a microscope” approach to AI interpretability. This methodology allows them to uncover insights into the inner workings of these systems that might not be apparent through simply observing their outputs. As they noted, this approach allows them to learn many things they “wouldn’t have guessed going in,” a crucial capability as AI models continue to evolve in sophistication.

The implications of this research extend beyond mere scientific curiosity. By gaining a better understanding of how AI models function, researchers can work towards building more reliable and transparent systems. Anthropic believes that this kind of interpretability research is vital for ensuring that AI aligns with human values and warrants our trust.

Their investigations delved into specific areas:

Multilingual understanding: Evidence points to a shared conceptual foundation enabling Claude to process and connect information across various languages.

Creative planning: The model demonstrates an ability to plan ahead in creative tasks, such as anticipating rhymes in poetry.

Reasoning fidelity: Anthropic’s techniques can help distinguish between genuine logical reasoning and instances where the model might fabricate explanations.

Mathematical processing: Claude employs a combination of approximate and precise strategies when performing mental arithmetic.

Complex problem-solving: The model often tackles multi-step reasoning tasks by combining independent pieces of information.

Hallucination mechanisms: The default behaviour in Claude is to decline answering if unsure, with hallucinations potentially arising from a misfiring of its “known entities” recognition system.

Vulnerability to jailbreaks: The model’s tendency to maintain grammatical coherence can be exploited in jailbreaking attempts.

Anthropic’s research provides detailed insights into the inner mechanisms of advanced language models like Claude. This ongoing work is crucial for fostering a deeper understanding of these complex systems and building more trustworthy and dependable AI.

The Hidden Risks of DeepSeek R1: How Large Language Models Are Evolving to Reason Beyond Human Understanding

In the race to advance artificial intelligence, DeepSeek has made a groundbreaking development with its powerful new model, R1. Renowned for its ability to efficiently tackle complex reasoning tasks, R1 has attracted significant attention from the AI research community, Silicon Valley, Wall Street, and the media. Yet, beneath its impressive capabilities lies a concerning trend that could redefine the future of AI. As R1 advances the reasoning abilities of large language models, it begins to operate in ways that are increasingly difficult for humans to understand. This shift raises critical questions about the transparency, safety, and ethical implications of AI systems evolving beyond human understanding. This article delves into the hidden risks of AI’s progression, focusing on the challenges posed by DeepSeek R1 and its broader impact on the future of AI development.

The Rise of DeepSeek R1

DeepSeek’s R1 model has quickly established itself as a powerful AI system, particularly recognized for its ability to handle complex reasoning tasks. Unlike traditional large language models, which often rely on fine-tuning and human supervision, R1 adopts a unique training approach using reinforcement learning. This technique allows the model to learn through trial and error, refining its reasoning abilities based on feedback rather than explicit human guidance.

The effectiveness of this approach has positioned R1 as a strong competitor in the domain of large language models. The primary appeal of the model is its ability to handle complex reasoning tasks with high efficiency at a lower cost. It excels in performing logic-based problems, processing multiple steps of information, and offering solutions that are typically difficult for traditional models to manage. This success, however, has come at a cost, one that could have serious implications for the future of AI development.

The Language Challenge

DeepSeek R1 has introduced a novel training method which instead of explaining its reasoning in a way humans can understand, reward the models solely for providing correct answers. This has led to an unexpected behavior. Researchers noticed that the model often randomly switches between multiple languages, like English and Chinese, when solving problems. When they tried to restrict the model to follow a single language, its problem-solving abilities were diminished.

After careful observation, they found that the root of this behavior lies in the way R1 was trained. The model’s learning process was purely driven by rewards for providing correct answers, with little regard to reason in human understandable language. While this method enhanced R1’s problem-solving efficiency, it also resulted in the emergence of reasoning patterns that human observers could not easily understand. As a result, the AI’s decision-making processes became increasingly opaque.

The Broader Trend in AI Research

The concept of AI reasoning beyond language is not entirely new. Other AI research efforts have also explored the concept of AI systems that operate beyond the constraints of human language. For instance, Meta researchers have developed models that perform reasoning using numerical representations rather than words. While this approach improved the performance of certain logical tasks, the resulting reasoning processes were entirely opaque to human observers. This phenomenon highlights a critical trade-off between AI performance and interpretability, a dilemma that is becoming more apparent as AI technology advances.

Implications for AI Safety

One of the most pressing concerns arising from this emerging trend is its impact on AI safety. Traditionally, one of the key advantages of large language models has been their ability to express reasoning in a way that humans can understand. This transparency allows safety teams to monitor, review, and intervene if the AI behaves unpredictably or makes an error. However, as models like R1 develop reasoning frameworks that are beyond human understanding, this ability to oversee their decision-making process becomes difficult. Sam Bowman, a prominent researcher at Anthropic, highlights the risks associated with this shift. He warns that as AI systems become more powerful in their ability to reason beyond human language, understanding their thought processes will become increasingly difficult. This ultimately could undermine our efforts to ensure that these systems remain aligned with human values and objectives.

Without clear insight into an AI’s decision-making process, predicting and controlling its behavior becomes increasingly difficult. This lack of transparency could have serious consequences in situations where understanding the reasoning behind AI’s actions is essential for safety and accountability.

Ethical and Practical Challenges

The development of AI systems that reason beyond human language also raises both ethical and practical concerns. Ethically, there is a risk of creating intelligent systems whose decision-making processes we cannot fully understand or predict. This could be problematic in fields where transparency and accountability are critical, such as healthcare, finance, or autonomous transportation. If AI systems operate in ways that are incomprehensible to humans, they can lead to unintended consequences, especially if these systems have to make high-stakes decisions.

Practically, the lack of interpretability presents challenges in diagnosing and correcting errors. If an AI system arrives at a correct conclusion through flawed reasoning, it becomes much harder to identify and address the underlying issue. This could lead to a loss of trust in AI systems, particularly in industries that require high reliability and accountability. Furthermore, the inability to interpret AI reasoning makes it difficult to ensure that the model is not making biased or harmful decisions, especially when deployed in sensitive contexts.

The Path Forward: Balancing Innovation with Transparency

To address the risks associated with large language models’ reasoning beyond human understanding, we must strike a balance between advancing AI capabilities and maintaining transparency. Several strategies could help ensure that AI systems remain both powerful and understandable:

Incentivizing Human-Readable Reasoning: AI models should be trained not only to provide correct answers but also to demonstrate reasoning that is interpretable by humans. This could be achieved by adjusting training methodologies to reward models for producing answers that are both accurate and explainable.

Developing Tools for Interpretability: Research should focus on creating tools that can decode and visualize the internal reasoning processes of AI models. These tools would help safety teams monitor AI behavior, even when the reasoning is not directly articulated in human language.

Establishing Regulatory Frameworks: Governments and regulatory bodies should develop policies that require AI systems, especially those used in critical applications, to maintain a certain level of transparency and explainability. This would ensure that AI technologies align with societal values and safety standards.

The Bottom Line
