Chrome's Prompt API lets web developers call Gemini Nano — Google's compact, locally-running language model — directly from JavaScript, without any server requests after the initial model download. The API accepts text, audio (AudioBuffer or Blob), and visual inputs (images, canvas elements, video frames), returns streaming text responses, and supports JSON Schema-constrained structured output for reliable data extraction. Sessions are created via LanguageModel.create(), with each session maintaining a token-aware context window that prunes older messages automatically while preserving system prompts. The Prompt API complements other Chrome AI primitives including the Summarizer, Writer, Rewriter, Translator, and Language Detector APIs — all running fully on-device. Model requires 22GB+ free disk space for the initial download; subsequent use works offline. This is a meaningful shift for web AI. Developers can now build privacy-preserving AI features — local transcription, smart autocomplete, content classification, on-page summarization — without touching a cloud API or paying per-token costs. Currently supports English, Japanese, and Spanish. Available via Chrome's Origin Trial program with broader rollout expected through 2026.

free-claude-code is a Python proxy that intercepts Anthropic API calls from Claude Code CLI, VSCode extensions, and IntelliJ, then routes them to alternative providers — NVIDIA NIM (40 free requests/minute), OpenRouter, DeepSeek, LM Studio, or llama.cpp locally. Change two environment variables and your existing Claude Code setup uses the new backend. The proxy supports per-model routing, letting you send Opus requests to one provider and Haiku to another. It handles thinking token parsing, heuristic tool call parsing for models that output tools as text, and smart rate limiting with proactive throttling. There's also Discord and Telegram bot support for remote autonomous coding sessions. This project exploded to nearly 10,000 GitHub stars in a day, making it the fastest-trending non-HuggingFace repo on the platform right now. The ethical picture is nuanced — it doesn't bypass Anthropic's servers, it routes to legitimately licensed models on other providers. But it deliberately sidesteps Anthropic's revenue model. Worth watching how Anthropic responds, and whether NVIDIA's free NIM tier survives the incoming traffic.
Reviewer scorecard
“The JSON Schema structured output is the feature I've been waiting for — finally you can extract clean data from user-typed text without a backend. The 22GB download is a real onboarding hurdle, but once the model is cached, the latency is basically zero compared to cloud APIs. This changes the math for privacy-sensitive consumer apps.”
“For the 80% of Claude Code usage that's just routine coding tasks, DeepSeek V4 via this proxy is genuinely indistinguishable in quality. I'm saving $200/month and the setup took five minutes. The per-model routing is smart engineering.”
“A 22GB model download as a prerequisite for a web feature is going to have terrible adoption outside of developer demos. Most users won't have that space or patience, and the English/Japanese/Spanish-only limitation rules it out for global products. Wait for the model to shrink before betting your product on this.”
“Let's be honest about what this is: a tool designed to take the Claude Code UX while cutting Anthropic out of the revenue. The open-source models it routes to are meaningfully worse for complex reasoning tasks, and you're one NVIDIA NIM policy change away from a broken workflow.”
“On-device inference in the browser is the endgame for consumer AI. No API keys, no latency, no data leaving the device — this is what private-by-default AI looks like. The browser becomes the AI runtime, and Google just got there first. The model size issue is a 2026 problem; by 2027 it'll be 2GB.”
“This is the natural result of building dev tooling on top of proprietary API pricing. It proves the interface is now the moat, not the model. Anthropic should take note: developers will build around cost walls if the cost walls are high enough.”
“Real-time image and canvas analysis directly in the browser opens up creative tooling that wasn't possible without a backend. Think live design feedback, style detection from reference images, or on-the-fly alt-text generation — all without a cloud API call. The streaming responses make it feel snappy enough for interactive UX.”
“The setup is too technical for most creatives, and the quality inconsistency across providers would drive me crazy mid-project. I'd rather pay for the real thing and get reliable results.”
