Worth attention

(untitled)
Google released Gemma 4 12B, an open-weight multimodal model that handles text, images, audio, and video without a separate encoder. At 12B parameters it's runnable on consumer hardware. Directly relevant if you're running local models via Ollama — expect it on ollama.com shortly.
(untitled)
Uber blew through its 2026 AI tool budget in four months and is now capping Claude Code usage. Simon Willison notes this isn't surprising given budgets were set before agentic coding tools took off. A concrete cost signal: even large companies are finding AI tool spend hard to predict. Worth watching as a solo dev using these tools daily.
(untitled)
Elixir 1.20 ships gradual typing — a major milestone for the language. Types are now checked at compile time with full inference, bringing Elixir closer to languages like TypeScript in developer experience while keeping its dynamic roots. Notable open source release even if you're not an Elixir user.
(untitled)
Builder tested multiple LLMs against a deliberately vulnerable app to see which could find and exploit real security bugs. Practical, reproducible security research with cost data. Relevant to anyone shipping web apps and wondering whether AI-powered security testing is viable.
(untitled)
Vercel CLI now supports `vercel curl --trace` to generate OpenTelemetry traces for any request. Useful debugging tool if you're on Vercel — trace a specific request end-to-end from your terminal.
(untitled)
HuggingFace blog on wiring MCP tools into a physical robot (Reachy Mini). Shows MCP expanding beyond chat and coding into robotics/hardware. Interesting signal for the MCP ecosystem.
