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.

Anthropic has shipped a focused terminal rendering update for Claude Code, its agentic coding assistant. The update introduces native mouse support inside the terminal interface — allowing users to click to position the cursor, scroll through output, and interact with UI elements without keyboard shortcuts. Alongside this, the team has addressed the flickering issue that plagued rapid output updates, replacing the previous rendering approach with a diff-based update system that only redraws changed portions of the terminal. The changes are largely invisible when things work but dramatically noticeable when they don't — flickering in an agentic coding tool that generates large code blocks rapidly is genuinely disruptive to flow. The mouse support makes Claude Code more accessible to developers who prefer point-and-click navigation and better aligns the experience with modern terminal emulator expectations. The update debuted at #8 on Product Hunt with 112 upvotes. For heavy Claude Code users, these are quality-of-life improvements rather than capability additions — but quality-of-life in a tool you use for hours a day compounds fast. Anthropic's willingness to ship focused rendering improvements signals continued investment in Claude Code as a product, not just a model API.
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.”
“The flickering was genuinely annoying during long agent runs — watching the terminal strobe while Claude generates 500 lines of code breaks concentration. Flicker-free rendering alone justifies this update. Mouse support is a nice-to-have for most devs but will matter a lot to anyone transitioning from GUI tools to terminal-first workflows.”
“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.”
“This is polish, not progress. While it's nice that Anthropic is fixing the terminal experience, these are bugs and missing features that probably shouldn't have shipped in the first place. The 'update' framing for what is essentially a bug fix and basic feature addition seems like marketing polish.”
“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.”
“The friction reduction in agentic coding tools is where the real productivity gains come from. Mouse support and flicker-free rendering aren't glamorous, but they're the kind of polish that separates toys from tools. Anthropic iterating on UX signals they're serious about Claude Code as an enduring product.”
“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.”
“Not directly relevant to design work, but as someone who uses Claude Code for building out web prototypes, the flickering was the one thing that made me reach for a GUI alternative. Flicker-free output makes long coding sessions much less visually taxing.”
