Strong software engineering performance

MAI-Thinking-1 (35B active, ~1T total parameters, MoE) has a smaller inference footprint than much larger models, yet is competitive with Claude Opus 4.6 on SWE-Bench Pro—coding power that you can run every day.

A model users genuinely enjoy

Putting humans first

Humanist Superintelligence means AI that’s both helpful and safe. We treat unsafe compliance and unnecessary refusal as defects in the same reinforcement learning loop as capability. The result: stronger safety on sensitive content without sacrificing helpfulness.
