MiniMax M2.7 Will Be Open Weights — Self-Evolving Model Handled 30-50% of Its Own RL Training

MiniMax announced that M2.7 will be released as open weights, a significant reversal from the proprietary API-only stance at launch. The model is architecturally novel: it autonomously triggered log-reading, debugging, and metric analysis to handle 30-50% of its own reinforcement learning development workflow. It scored 56.22% on SWE-Pro at $0.30/$1.20 per million input/output tokens — roughly one-third the cost of GLM-5 — making it a strong candidate for enterprise coding workloads once weights drop.
