Genkit

Want to give your Genkit agents a real browser? 🌐 We built `genkitx-playwright`, a drop-in middleware package that empowers your AI agents to perform browser automation: 🌐 Navigate pages and manage tabs 🖱️ Click, type, and fill out forms 📸 Take screenshots of page states Instead of guessing CSS selectors, the middleware uses accessibility snapshots with element references to guide your models reliably.

"Is it thinking or is it broken?" 🤔 When a reasoning model takes time to formulate a response, users are often left staring at a blank screen. This perceived latency is one of the biggest UX hurdles in generative AI. We just published a new guide on building transparent AI chat UIs using Genkit to solve this problem. Learn how to leverage server-sent event (SSE) streaming capabilities in Genkit to stream the internal reasoning process (thoughts) of a model in real-time alongside the final response. The walkthrough includes: 🧠 Configuring your model to include thoughts 🌊 Separating reasoning streams from final text chunks ⚛️ Pre-built React components to render thoughts dynamically Read the full blog post on the Genkit site: https://lnkd.in/g75CPemk

Genkit Python SDK v0.7.0 is officially live! 🐍🚀 We are continuing to expand language support and bring production-grade capabilities to Python developers. In this release, we have focused on giving you more control over the generation pipeline, adding pre-built resilience tools, and making it easier to integrate Genkit into your production web applications. Here is what is new: ✨ Pluggable Middleware: Intercept the generation loop at key lifecycle points (wrap_generate, wrap_model, and wrap_tool) to inspect/mutate inputs/outputs or raise Interrupts. 🛡️ Production-Ready Plugins: A new official `genkit-plugin-middleware` package with smart retries (exponential backoff), model fallbacks, tool approval flows, and filesystem sandboxing. Check out the full release notes, upgrade your dependencies, and let us know what you build! https://lnkd.in/gjwHZZUh

On-device AI brings zero token costs, offline support, and unbeatable privacy. The cloud brings high-reasoning ceilings and unlimited world knowledge. Real hybrid AI is about routing requests dynamically between them. Google Developer Expert Sasaha Denisov just published a must-read architectural guide on building hybrid AI in Flutter using Genkit Dart and genkit_flutter_gemma. 💡 Level 1: Simple ternary swapping driven by app context (e.g., keeping PII local). 🧠 Level 2: Using a fast, local 1B classifier model to decide query complexity on-device. 🛡️ Level 3: Leveraging Genkit middleware to gracefully handle transient failures. 🔄 Level 4: Building a custom fallback service to degrade gracefully from cloud to local. With Genkit's provider-neutral design, switching between cloud Gemini and a local Gemma model is as simple as changing a single `model:` reference in your code. https://lnkd.in/gdw7BR-U

Genkit JS & CLI v1.36.0 is officially live! 🚀 We’ve just released a fresh set of updates to enhance your developer experience, bring new model capabilities, and harden your production AI workflows. Here is what is new in this release: 💻 New CLI Commands: Retrieve trace data directly from your terminal with the new `trace:get` and `trace:list` commands, perfect for debugging workflows without leaving the command line. 🧠 Antigravity Agent Model: Added support for the Antigravity agent model in the Google GenAI plugin. ☁️ Vertex AI Updates: Added support for `-latest` model versions to ensure you always build with the most up-to-date models. 🤖 Anthropic SDK Upgrades: The Anthropic SDK is now updated to ^0.97.1 to gracefully handle `input_json_delta` stream events instead of throwing errors. We’ve also shipped critical bug fixes, including resolved Claude thinking support in Vertex AI Model Garden and more robust tool response handling in the filesystem middleware.

Dart developers can now build full-stack AI applications with official Genkit Dart! 🎯 But moving AI from prototype to production means thinking about security and abuse prevention. In this video, Nohe demonstrates how to secure a Genkit Dart backend (using a Shelf server) for a virtual try-on application. 🔒 Device Attestation: Using Firebase App Check to verify legitimate clients. 🔐 User Authorization: Checking custom claims in authorization headers. ⏱️ Rate Limiting: Using Firestore aggregation queries to keep costs in check. 🛡️ Prompt Injection Prevention: Restricting inputs to product IDs rather than arbitrary URLs.

🚀 Genkit JS & CLI v1.35.0 is officially live! We are continuing to expand model support and harden production reliability. Here is what is new in this release: ✨ Gemini 3.5 Support: We have added support for Gemini 3.5 and Gemini 3.5 Flash in the Google GenAI plugin. 🔍 Better Debug Traces: Improved trace visibility to help you debug complex AI workflows. 🛡️ Smarter Error Handling Check out the full release notes and upgrade your projects today: https://lnkd.in/gpBG7FcU

Building production-ready AI agents requires more than just powerful models and careful prompting. You need reliability, safety, and fine-grained control. Genkit is our open-source framework for building full-stack, agentic applications. With the new middleware system, you can now use composable hooks to intercept generation calls and inject custom behaviors. Here is what is available today in TypeScript, Go, and Dart: 🔄 Automatic Retries: Handle transient errors with exponential backoff. 🛡️ Tool Approval: Implement human-in-the-loop safety for autonomous agents. 📦 Filesystem Access: Give your models scoped, safe access to the local filesystem. You can also build and stack your own custom middleware to enforce business rules or security policies. Read the full announcement on the Google Developers Blog https://lnkd.in/gQnbJPsX

We love seeing our community of educators grow for Genkit!
