MiniMax M2.7 is open-source!

MiniMax open-sourced M2.7 and said its research agent now handles 30%–50% of the R&D workflow. The post says the agent covers literature review, experiment orchestration, log debugging, code fixes, and merge requests; M2.7 also rewrote its own harness for 100+ automated rounds, with a 30% gain on internal coding evals.

Why it matters: HKR-H/K/R all pass: open-sourcing plus a research agent doing 30%-50% of R&D is a strong hook, and the post includes 100+ self-rewrite loops with +30% internal coding eval. It stays at 78 because license, repo, benchmark context, and external reproduction are not disclosed.
