DeepSeek-Reasonix Adds Anthropic and Responses API Compatibility, Then Ships Four Releases in 31 Hours
esengine/DeepSeek-Reasonix (MIT, 28,730 stars) cut v1.19.0 on 2026-08-01 adding DeepSeek Anthropic and Responses API support along with model-polling performance work and hardened session persistence and permission handling, then followed with preview.3 and stable v1.19.1 by 2026-08-02 00:41 UTC, plus matching desktop builds. The repo is engineered around prefix-cache stability with the explicit pitch of leaving it running. Two things temper the momentum: v1.19.1's fixes include wallet currency alignment, meaning this terminal coding agent carries a payments surface, and it now sits at 1,363 open issues, an issue-to-star ratio far above comparable harnesses.
