DeepSeek launches Reasonix: terminal coding agent with cache-first V4-Flash
Cache-first loop and /pro escalation turn api.deepseek.com into a full coding agent—no IDE needed.
Deep Dive
DeepSeek's agent-integrations docs now list Reasonix, a terminal coding agent built directly for api.deepseek.com. It runs a cache-first loop with V4-Flash by default and offers /pro escalation. The guide covers setup steps and what a session really costs.
Key Points
- Reasonix is a terminal coding agent built natively for api.deepseek.com, with V4-Flash as the default model.
- Cache-first loop reduces token spend by reusing context across agent iterations; /pro escalates to a stronger model.
- V4-Flash scored 82.7 on Terminal Bench 2.1, beating V4-Pro-Preview on agentic benchmarks and now supports Responses API and Codex.
Why It Matters
Reasonix gives developers a fast, cost-efficient terminal AI agent on DeepSeek's own API, intensifying the coding-agent war.
