MiniMax-M3 — Production Wiring (empirical)

The M3 companion to ../minimax/SKILL.md (M2.7). Every claim here was live-probed 2026-06-01 (fast subset re-verified 2026-06-23) on the Plus-High-Speed key. Full evidence + copy-paste snippets: ../../references/M3-EMPIRICAL.md.

Self-Evolving Skill: improves through use. If a flag stopped working, a limit moved, or the docs caught up with reality — fix this file + references/M3-EMPIRICAL.md immediately, don't defer. Re-verify with the scripts below before changing a documented fact.

The one rule: default to reasoning_split: true

M3 still emits <think>…</think> inside content by default (same footgun as M2.7). Setting reasoning_split: true moves the reasoning into a separate reasoning_content / reasoning_details field and leaves content clean — no regex stripping. This is the chosen default profile for everything migrating off M2.7-highspeed.
