Why do I see Unknown model minimaxMiniMaxM21

This means the provider isn’t configured (no MiniMax provider config or auth profile was found), so the model can’t be resolved. A fix for this detection is in 2026.1.12 (unreleased at the time of writing).
Fix checklist:
Upgrade to 2026.1.12 (or run from source main), then restart the gateway.
Make sure MiniMax is configured (wizard or JSON), or that a MiniMax API key exists in env/auth profiles so the provider can be injected.
Use the exact model id (case‑sensitive): minimax/MiniMax-M2.1 or minimax/MiniMax-M2.1-lightning.
Run:
openclaw models list
and pick from the list (or /model list in chat).
