Mimo struggles with my custom harness. (Ignores the instructions and defaults back to its own preferred tool calling syntax.)

Flash handles it fine, which I found amusing. (Since Mimo is supposed to be opus level!) But Flash seems to work even better in Claude Code...

With smaller models I always have the issue of needing to adapt myself to their preferred workflow... which sort of defeats the purpose. Price is hard to beat tho :)

Mimo v2.5 non-pro seems to do better with tool usage than its Pro sibling, is much cheaper and solves 90% of the same problems. I use Pro only for one-off tasks that require complex reasoning: memory management bugs, algorithms, planning.

When it gets stuck, I get one-shot advice from Claude or DS Pro. I’ve done massive amounts of work for cheap this way.

Thanks. I found One Weird Trick to make Mimo v2.5 Pro work in my harness, which is that I just added an example bash tool usage to the system prompt. Now it works fine.

The issue was that my previous instructions had <command> as a placeholder. But the model started wrapping bash commands in <command></command> tags... haha. Now that it has an actual example it just works properly.
