MiniMax just dropped M2.7, the first AI model that helped train itself.

100+ autonomous optimization loops during training. Zero human involvement for 30-50% of the process. 56.2% on SWE-Bench Pro, within 1 point of Opus 4.6 and GPT 5.4. 50x cheaper.

A Chinese lab just matched frontier models while pioneering self-improving AI. Available today via API.

Benchmarks aren't real-world performance though. Real coding workflows will be the test.
