DeepSeek Publishes Official Reasonix Integration Guide

Checked on June 20, 2026: DeepSeek's official Reasonix integration page now documents `npx reasonix code`, stores the API key in `~/.reasonix/config.json`, defaults to DeepSeek V4 Flash, and exposes `/pro` plus `/preset max` for stronger reasoning when needed.

What we verified on June 20, 2026

  • DeepSeek now has an official Reasonix integration page inside the agent-integrations section of the API docs.
  • The official startup path is direct and repo-scoped: enter the target project and run npx reasonix code.
  • The page says the first run persists the DeepSeek API key into ~/.reasonix/config.json, which makes the setup path more concrete than a generic env-var-only article.
  • DeepSeek documents a Flash-first routing pattern: Reasonix defaults to DeepSeek V4 Flash for cheaper iteration.
  • The same page gives two explicit escalation commands: /pro for the next turn and /preset max for a Pro-heavy whole-session route.
