MiniMax runs 1/16th the price of Claude Opus for OpenClaw workflows. Opus starts at $5 per million tokens; MiniMax sits at roughly $0.30 per million tokens. The MiniMax coding plan goes for under $10 (starter tier) and gives you 100 prompts every 5 hours — a fixed package, not pay-per-use. The host's own Opus run burned $30 in a single hour, which is the exact problem MiniMax solves.
The "Dumb Zone" Failure Mode
The model enters what the host calls a "dumb zone" once the soul.md file swells. His original soul was 300 lines. At that size, the agent "starts messaging your girlfriend instead of building a presentation." MiniMax — like several other Chinese models — degrades sharply when context is overloaded. Compressing soul.md to 15–30 lines and trimming agents.md (the bootstrap file) brought it back into the "smart zone."
M2.1 and M2.5 Both Failed Out of the Box
Ron ran M2.1 first, "didn't do so well," upgraded to M2.5, "still didn't do so well." The real fix wasn't a model upgrade — it was a full reinstall from scratch (requires SSH access to your server). Random files scattered across directories were "muddying up" the context window, confirmed independently by Cursor and an orchestrator agent.
Feed It the GitHub, Skip the Reinvention
For the daily news report, Opus was used to walk through the workflow (research → plan → filter → present). MiniMax can't guide that process on its own. The workaround: scrape an existing open-source GitHub repo, set a cron job, and let it run overnight using the 5-hour refresh window.
The Claude Code Hack
You can route MiniMax's coding plan through Claude Code by swapping the Anthropic base URL to the MiniMax Anthropic endpoint and using the coding-plan key as the token. You get Claude Code's interface at MiniMax's pricing.
The OS Reinstall Trick (Zebra)
The host's "trick on Zebra" — reinstalling the OS — applied to OpenClaw too: delete the agent directory, rewrite soul.md short, compact agents.md, and start over. Don't try to fix a polluted directory; nuke it.
