DeepSeek-Reasonix Made Its Go Rewrite the Default Branch and Put the TypeScript Line Into Maintenance
DeepSeek-Reasonix, a terminal coding agent at 35,239 stars and pushed 2026-08-29, has moved active development to a Go rewrite on the `main-v2` branch, now the repo default, with the 0.x TypeScript line in maintenance and receiving bug fixes only. Its stated design constraint is prefix-cache stability, keeping the prompt prefix byte-stable so long sessions keep hitting cache rather than re-paying for context. That is the same lever Claude Code just exposed in `/cost`, arriving here as an architecture decision instead of a metric.
