Google Magic Mirror

The new “Google Magic Mirror” showcases the JavaScript GenAI SDK and Gemini API's interactivity. A mirror, a common object, becomes a discussion interface in this idea.

The Google Magic Mirror optimises real-time communication. Interactivity relies on the Live API, which allows real-time voice interactions. The mirror participates in a genuine back-and-forth discussion in text or voice by digesting speech as you speak, unlike systems that merely listen for one order.

The Live API powers bidirectional, real-time audio streaming and communication. One of Live API's most dynamic features is speech detection during playback. This interruption can dynamically change the tale and dialogue, enabling text and aural dialogue, depending on the user's actions.

Google Magic Mirror can be a “enchanted storyteller” and a communication tool. This feature uses the Gemini model's advanced generating capabilities. The storytelling component can be customised by delivering system commands that affect the AI's tone and conversational style. By modifying speech configurations during initialisation, the AI can respond with different voices, accents, dialects, and other traits. AI language and voice are changed by speech setting.

The project combines the model's real-world connection for contemporary information seekers. The Google Magic Mirror may use Grounding with Google Search to provide real-time, grounded news. This ensures that the mirror's responses are not limited to its training material. Starting with Google Search ensures current, reliable information.

Image generation by the mirror adds a touch of “visual alchemy” to the experience. Function Calling from the Gemini API lets the mirror create images from user descriptions. This strengthens the engagement and deepens storytelling. The Gemini model determines whether a user request creates an image and triggers a function based on provided features.

The picture production service receives a detailed prompt from the user's spoken words. Function Calling is a more extensive feature that allows Gemini models to speak with publically accessible external tools and services, such as picture generation or bespoke actions, based on the discussion.

The user experience hides the technology intricacies, while strong Gemini model aspects provide this “magical experience” in the background. Among these technical traits:

Live API controls bidirectional, real-time audio streaming and communication.

Gemini models can call functions from external tools and services like picture production or bespoke actions based on the discussion.

Using Google Search for current, accurate information.

System directives shape AI tone and conversation.

Speech configuration changes AI responses' tone and vocabulary.

Modality control lets the Gemini API anticipate output modalities or respond in text or voice.

The inventors say their Gemini-enabled Google Magic Mirror is more than a gimmick. It shows how advanced AI may be blended into real life to create helpful, fascinating, and even miraculous interactions. Flexibility allows the Gemini API to enable many more applications. Immersive entertainment platforms, dynamic educational tools, and personalised assistants are possible applications.

The Google Magic Mirror's code is available on GitHub for those interested in its technical operation. Hackster.io also provides a detailed build tutorial. The founders of X and LinkedIn want the community to imagine what their Google magic mirror could do and contribute ideas and other Gemini-enabled products.

Google launched context caching in May 2024, allowing developers to explicitly save 75% of model reused context. Today, the Gemini API adds implicit caching, a popular request.

Implicit caching using Gemini API

Implicit caching saves developers cache costs by eliminating the need for explicit cache construction. Sending a request to a Gemini 2.5 model with the same prefix as a previous request can now cause a cache hit. You will enjoy the same 75% token discount as it dynamically passes cost savings back to you.

To increase the likelihood of a cache hit, include context that may vary from request to request, such as a user's inquiry, at the end of the prompt. More implicit caching best practices are in the Gemini API documentation.

Google Developers reduced Gemini 2.5 Flash's minimum request size to 1024 tokens and 2.5 Pro's to 2048 tokens to boost cache hits.

Gemini 2.5: Token discounts explained

Consider using its explicit caching API, which supports Gemini 2.5 and 2.0 models, to save money. If you use Gemini 2.5 models, the use information will show cached_content_token_count, which shows how many tokens in the request were cached and charged at the reduced price.

Preview models may be modified and have stricter rate limitations before stabilising.

Context caching

Standard AI processes may feed models the same input tokens. The Gemini API has two caching methods:

Automated implicit caching (no cost savings)

Caching manually (guaranteed savings)

Gemini 2.5 models default to implicit caching. If a request involves cached content, Google Developers refund you promptly.

Explicit caching can reduce costs, but it requires more developer work.

Implicit cache

The default setting for all Gemini 2.5 models is implicit caching. Should your request reach caches, cost savings are promptly passed on. This requires no action. It takes effect May 8, 2025. For context caching, 2.5 Flash and 2.5 Pro need 1,024 and 2,048 input tokens.

Increase implicit cache hit probability:

Consider opening your prompt with common, large content.

Use comparable prefixes to send requests fast.

Token cache hits are shown in the response object's usage_metadata field.

Explicit cache

Using the Gemini API's explicit caching, you can send content to the model once, cache the input tokens, and utilise them for other queries. Using cached tokens is cheaper than passing in the same tokens at precise volumes.

Caches can store tokens for a specified time before being automatically removed. This is the TTL for caching. Unset TTLs default to one hour. The caching cost depends on input token size and persistence period.

Gemini Live API

Create live voice-driven agentic apps using Vertex AI Gemini Live API. All industries seek aggressive, effective solutions. Imagine frontline personnel using voice and visual instructions to diagnose issues, retrieve essential information, and initiate processes in real time. A new agentic industrial app may be created with the Gemini 2.0 Flash Live API.

This API extends these capabilities to complex industrial processes. Instead of using one data type, it uses text, audio, and visual in a continuous livestream. This allows intelligent assistants to understand and meet the demands of manufacturing, healthcare, energy, and logistics experts.

The Gemini 2.0 Flash Live API was used for industrial condition monitoring, notably motor maintenance. Live API allows low-latency phone and video communication with Gemini. This API lets users have natural, human-like audio chats and halt the model's answers with voice commands. The model processes text, audio, and video input and outputs text and audio. This application shows how APIs outperform traditional AI and may be used for strategic alliances.

Multimodal intelligence condition monitoring use case

Presentation uses Gemini 2.0 Flash Live API-powered live, bi-directional, multimodal streaming backend. It can interpret audio and visual input in real time for complex reasoning and lifelike speech. Google Cloud services and the API's agentic and function calling capabilities enable powerful live multimodal systems with a simplified, mobile-optimized user experience for factory floor operators. An obviously flawed motor anchors the presentation.

A condensed smartphone flow:

Gemini points the camera at motors for real-time visual identification. It then quickly summaries relevant handbook material, providing users with equipment details.

Real-time visual defect detection: Gemini listens to a verbal command like “Inspect this motor for visual defects,” analyses live video, finds the issue, and explains its source.

When it finds an issue, the system immediately prepares and sends an email with the highlighted defect image and part details to start the repair process.

Real-time audio defect identification: Gemini uses pre-recorded audio of healthy and faulty motors to reliably identify the issue one based on its sound profile and explain its results.

Multimodal QA on operations: Operators can ask complex motor questions by pointing the camera at certain sections. Gemini effectively combines motor manual with visual context for accurate voice-based replies.

The tech architecture

The demonstration uses Google Cloud Vertex AI's Gemini Multimodal Livestreaming API. The API controls workflow and agentic function calls while the normal Gemini API extracts visual and auditory features.

A procedure includes:

Function calling by agents: The API decodes audio and visual input to determine intent.

The system gathers motor sounds with the user's consent, saves them in GCS, and then begins a function that employs a prompt with examples of healthy and faulty noises. The Gemini Flash 2.0 API examines sounds to assess motor health.

The Gemini Flash 2.0 API's geographical knowledge is used to detect and highlight errors by recognising the intent to detect visual defects, taking photographs, and invoking a method that performs zero-shot detection with a text prompt.

Multimodal QA: The API recognises the objective of information retrieval when users ask questions, applies RAG to the motor manual, incorporates multimodal context, and uses the Gemini API to provide exact replies.

After recognising the intention to repair and extracting the component number and defect image using a template, the API sends a repair order via email.

Key characteristics and commercial benefits from cross-sector usage cases

This presentation highlights the Gemini Multimodal Livestreaming API's core capabilities and revolutionary industrial benefits:

Real-time multimodal processing: The API can evaluate live audio and video feeds simultaneously, providing rapid insights in dynamic circumstances and preventing downtime.

Use case: A remote medical assistant might instruct a field paramedic utilising live voice and video to provide emergency medical aid by monitoring vital signs and visual data.

Gemini's superior visual and auditory reasoning deciphers minute aural hints and complex visual settings to provide exact diagnoses.

Utilising equipment noises and visuals, AI can predict failures and eliminate manufacturing disruptions.

Agentic function invoking workflow automation: Intelligent assistants can start reports and procedures proactively due to the API's agentic character, simplifying workflows.

Use case: A voice command and visual confirmation of damaged goods can start an automated claim procedure and notify the required parties in logistics.

Scalability and seamless integration: Vertex AI-based API interfaces with other Google Cloud services ensure scalability and reliability for large deployments.

Use case: Drones with cameras and microphones may send real-time data to the API for bug identification and crop health analysis across huge farms.

The mobile-first design ensures that frontline staff may utilise their familiar devices to interact with the AI assistant as needed.

Store personnel may use speech and image recognition to find items, check stocks, and get product information for consumers on the store floor.

Real-time condition monitoring helps industries switch from reactive to predictive maintenance. This will reduce downtime, maximise asset use, and improve sectoral efficiency.

Use case: Energy industry field technicians may use the API to diagnose faults with remote equipment like wind turbines without costly and time-consuming site visits by leveraging live audio and video feeds.

How to make a crossword puzzle in Google Docs

Google know it’s a lot to take in, but this year at Google I/O, they made a tone of amazing announcements! So Microsoft thought, what better way to celebrate the start of Google I/O Connect event series than to take a playful look back at some of the most amazing tools we showed off during I/O? The I/O Google Crossword Puzzle is the outcome!

This is a modern take on the traditional Google Crossword Puzzle that not only assesses your proficiency with I/O concepts but also provides you with an interactive demonstration of the capabilities of Firebase, Flutter, and the Gemini API.

Tips for solving the I/O Crossword This is how it operates: Select a team based on one of the four mascots; this team will dictate the colour your spaces change to upon solving a word. Next, select a location on the board to begin. Try the “ask for a hint” option if you run into trouble solving your word.

How the Gemini API helped us create the I/O Crossword This year, they gave Gemini Advanced access to both of the Google I/O keynotes and requested that it produce current, tech-related information for a Google Crossword Puzzle, making the game an enjoyable way to learn about I/O news. He used Gemini’s assistance to construct the game’s 320 words and clues.

The game’s UI and mechanics were created using our development tools, Flutter, Dart, Firebase, Project IDX, Google Chrome, and Google Cloud, and they incorporated the AI-generated content into the final product.

It also integrated the AI-powered hint feature using these techniques. The goal of a Google Crossword Puzzle is to solve the words using the clues provided, but previously all experienced the frustration of not being able to pronounce a word that seems obvious or of a hint that doesn’t quite work out.

They included AI directly into the game to give you nudges, just enough to keep your brain cells going and to give you that satisfying feeling when you finally figure out the code, so you don’t have to go to Google Search for a little assistance.

The purpose of the I/O Crossword is to get you thinking about how you may utilize the Gemini API to improve upon well-known experiences or to develop brand-new ones.

You will be guided through all the necessary steps to comprehend, solve, and become an expert in I/O Crosswords by this in-depth guide.

Knowing the Fundamentals of I/O Crosswords How Do I/O Crosswords Work? I/O Crosswords are a cross between a logic puzzle and a standard crossword. To complete the grid, you must identify the proper input and output for each process or transformation that each puzzle clue explains.

Important Elements of I/O Crosswords Clues: The hints will usually explain a procedure or a role. Similar to “Input a number, output its square.”

Grid: The grid has empty squares that must be filled in with the letters or numbers that correspond to each clue’s solution.

Junctions: I/O Crossword answers overlap with each other, just like traditional crosswords do, offering more clues through shared letters or numerals.

Techniques for Finishing I/O Crosswords Begin with Basic Hints Start by figuring out and solving the easier hints that you know the answers to. These can help you get started on the puzzle and offer junctional hints for increasingly difficult clues.

Seek Out Common Patterns I/O Crosswords frequently use logical and mathematical patterns. Learn how to do common operations including addition, subtraction, multiplication, and simple string manipulations.

Apply Reasoned Inference Utilize rational inference to reduce the pool of potential solutions. Rethink your assumptions and take into account different options if a particular input/output relationship doesn’t mesh well with the intersecting replies.

Cross-Reference with Cross-Overs Take use of the points where various responses intersect. When a clue is solved correctly, it can expose important letters or numbers that help solve other clues nearby.

Advanced I/O Crossword Strategies Examining Complicated Hints For more difficult hints, divide the procedure into more manageable steps. Complete each step on its own, then add all the answers to get the final solution.

Making Use of Outside Resources

Use outside resources like dictionaries, programming references, and mathematical tables without hesitation. These can offer the definitions or background information needed to interpret complex hints.

Maintaining a Regular Practice To become proficient in I/O Google Crossword Puzzle, you must practice frequently. You will get more comfortable with typical clue structures and solving methods as you complete more puzzles.

An Example of a Puzzle with a Solution Walkthrough To demonstrate the method of solving an I/O Crossword, let us go through an example.
