DeepSeek's official docs now publish a Reasonix integration page with direct `npx` startup, local config persistence, and Pro-vs-Flash switching guidance

Accepted official-source monitoring note

Today's accepted item stays DeepSeek-first and uses a current official DeepSeek documentation page because the public X surface was still not safely crawlable in this run. DeepSeek's English homepage still anchors the official @deepseek_ai account, but the direct X timeline did not expose a readable current post here, so the publish-safe choice is the newest official developer-support page we could verify live.

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.

Why this is publishable

This is a current official DeepSeek developer-support surface, not a rumor, product-listing change, or recycled social screenshot.

1. It gives a first-party Reasonix setup contract instead of relying on community copy or old install notes.
2. It adds operational details that matter for support intent: where the key is stored, what command starts the tool, and how Pro versus Flash is selected.
3. It is not a duplicate of the earlier GitHub Copilot, Copilot CLI, Hermes, Deep Code, OpenCode, Pi, WorkBuddy, Kilo Code, or Oh My Pi items already published on the site.

Why this matters for DeepSeek-first SEO pages

• Reasonix support pages can now target official DeepSeek setup steps instead of independent blog summaries alone.
• The docs give a clean way to explain Flash-first cost control with explicit Pro escalation, which matches real DeepSeek routing intent.
• Developers searching for ~/.reasonix/config.json, npx reasonix code, or /preset max now have a verified official DeepSeek reference point.

Rejected candidates today

• Official X timeline as the primary source: rejected for this run because the homepage anchor was visible but the direct x.com/deepseek_ai timeline still did not expose readable current post content here.
• The homepage V4 Preview anchor: official, but older and already overlapped by existing V4 coverage.
• The current OpenClaw integration page: official and accepted as a guide opportunity for this run, but weaker than Reasonix as the single news headline because it is more onboarding-oriented and less specific about DeepSeek-native workflow routing.
• The current Langcli integration page: official, but weaker than Reasonix because the published quick-start path points users to LangRouter rather than a direct DeepSeek Platform key route.
• Status-page uptime alone: official, but weaker than a new documentation surface that changes how developers actually wire a coding agent.

Editorial takeaway

The safest official DeepSeek story today is a Reasonix integration documentation check: DeepSeek's own docs now publish the direct npx reasonix code startup path, the local config location, and the exact Flash-to-Pro switching commands. That is stronger and newer than recycling an older X post that still could not be fully verified live.
