Test-Drive

Chrome:

1. Download latest Chrome Canary
2. Sign up for early access here.
3. Enable experimental flags for Prompt API and on-device optimization

Prompt API for Gemini Nano
chrome://flags/#prompt-api-for-gemini-nano
Enables the exploratory Prompt API, allowing you to send natural language instructions to a built-in large language model (Gemini Nano in Chrome). Exploratory APIs are designed for local prototyping to help discover potential use cases, and may never launch. These explorations will inform the built-in AI roadmap [1]. This API is primarily intended for natural language processing tasks such as summarizing, classifying, or rephrasing text. It is NOT suitable for use cases that require factual accuracy (e.g. answering knowledge questions). You must comply with our Prohibited Use Policy [2] which provides additional details about appropriate use of Generative AI. – Mac, Windows, Linux, ChromeOS, Android, Lacros

chrome://flags/#optimization-guide-on-device-model
Enables the optimization guide to execute ****** on device. – Mac, Windows, Linux, ChromeOS, Lacros

Android:

• Currently available on Pixel 8 Pro, Pixel 8, Pixel 8a, and Samsung S24 Series
• Accessed through Google AI Edge SDK for Android

Impact on Web and Mobile Experiences

1. Enhanced Content Consumption: AI-powered summaries and classifications may reduce time spent on individual pages or documents.
2. Improved Accessibility: AI-driven rephrasing and image descriptions make content more digestible for all users.
3. Offline Functionality: AI features work without internet connection, improving app resilience.
4. Privacy-Focused Applications: On-device processing enables AI features for sensitive data without cloud transmission.

SEO and UX Considerations

1. Content Optimization: Websites may need to adapt content to be more “AI-friendly” for easy extraction and summarization.
2. User Behavior Shifts: Changes in how users interact with content may require evolving SEO and UX strategies.
3. Performance Expectations: Users may expect faster, smarter interactions across web and mobile platforms.
4. Hybrid AI Approaches: Developers should consider combining on-device and cloud-based AI for optimal performance and coverage.

Gemini Nano’s integration into Chrome and Android devices marks a significant step towards ubiquitous, efficient AI. As this technology develops, it will reshape how users interact with digital content, offering new opportunities and challenges for developers, marketers, and content creators.

Summary from Google’s Official Page

• Model Size Challenges:
  • Generative AI ****** are about 1000 times larger than the median web page size.
  • AI ****** for various use cases can range from 10s to 100s of megabytes.
  • Downloading these ****** for each website is impractical for both developers and users.
• Early Preview Program:
  • Google is seeking developer input to shape APIs and ensure they meet use cases.
  • Developers can join the early preview program to provide feedback and test in-progress APIs.
  • The Chrome AI developer public announcements group will notify members of new API availability.
• Expert ******:
  • These ****** focus on specific use cases, offering higher performance and quality.
  • Example: A translation API built with an expert model focused on translating content to new languages.
  • Expert ****** typically have low hardware requirements.
• Hardware Acceleration:
  • The browser’s AI runtime is optimized for available hardware (GPU, NPU, or CPU).
  • This optimization ensures the best performance on each device without developer intervention.
• Hybrid AI Approaches:
  • Complexity: On-device AI for specific, approachable use cases; server-side for complex scenarios.
  • Resiliency: Server-side by default, on-device for offline or poor connectivity situations.
  • Graceful Fallback: Offer server-side AI for devices not meeting hardware requirements or lacking built-in AI support.
• Browser Architecture and APIs:
  • Task APIs: Designed for specific functions like translation or summarization.
  • Exploratory APIs (for prototyping):
    • Prompt API: Sends natural language tasks to the built-in LLM (Gemini Nano in Chrome).
    • Fine-tuning (LoRA) API: Improves LLM performance using Low-Rank Adaptation fine-tuning.
• Future Developments:
  • Google is developing web platform APIs and browser features to integrate AI ****** directly into the browser.
  • This includes Gemini Nano, designed for local execution on modern desktop and laptop computers.
  • The implementation is experimental and subject to change based on testing and feedback.
• Integration with Existing Technologies:
  • For Gemini ******, developers can use backend integration (Python, Go, Node.js, or REST).
  • Web applications can implement Gemini using the new Google AI client SDK for Web.
