Is Claude the Best AI Model for OpenClaw?

The core fact: Claude is the smoothest OpenClaw model, MiniMax is the cheapest, and the right choice depends on whether you can think for the model

The cost gap is brutal and concrete

Opus bills at $5 per million input tokens, Sonnet at $3 (60% of Opus), and MiniMax at $0.30 per million tokens. The Boxmining team logs $3 to $10 per day for normal OpenClaw usage, but heavy multi-agent team sessions have spiked to $30 per day on Claude. Ron runs the same workloads on MiniMax inside the $20/month plan. If you're not optimizing for cost, you will be soon.

Opus beats Sonnet on architecture choices, not just quality

Building the Box95 website, Sonnet produced a 3,000-line vanilla JavaScript file — "building a house with your bare hands." Opus refused the approach, pulled in React, and made the site maintainable. The takeaway: run Opus first to pick the framework, then drop to Sonnet or MiniMax for execution. Going cheap on day one with Sonnet wasted more time than it saved.

Claude decomposes tasks; MiniMax executes them

For a multi-step daily briefing (gather tweets → web research → analyze → slides), Opus broke the work into steps on its own. MiniMax on the same prompt "just fetched headlines" with no analysis. The fix was pointing MiniMax at the World Monitor GitHub repo, letting it study the codebase, then scheduling a 6 a.m. cron — a workaround Claude doesn't need.

Use Claude if you can't prompt in steps

Opus is "really good at task solving" and "breaking down large tasks." If you're not a programmer and don't naturally decompose prompts, Claude "guesses what you mean." If you already have step-by-step instructions written out, MiniMax is "super efficient" and won't add unwanted extras the way Claude does.

Recommendation: staged model switching

New OpenClaw users: start on a Claude plan for the first 1–2 weeks. Once you can write the prompt decomposition yourself, migrate to MiniMax. Experienced developers with documentation prepared can skip Claude entirely and stay on the $20/month MiniMax plan.
