v0.12.104: @newsroom.writer: free models, your own key

A new article, Free models, your own key: which free model APIs a reader can call from a web page with their own key, as of 18 October 2026. Each provider's pricing, limits, models and terms were read that day, and every chat endpoint was tested with a CORS preflight from https://newsroom.sgit.ai. Four providers pass both tests (Groq, Gemini through AI Studio, Mistral's free mode and OpenRouter's free models); Cloudflare Workers AI needs a Worker; NVIDIA fails both; and the 2026 changes are listed. The bring-your-own-key design it proposes is not yet built. Figures use the new fi- prefix.
