feat(minimax): add MiniMax-M3.1-Flash-Preview with its always-on thinking contract - #6304
Conversation
…king contract MiniMax published MiniMax-M3.1-Flash-Preview on 2026-09-27 (Token Plan and MiniMax Code only, 1M context). Both MiniMax presets list it with efforts low..max defaulting to max. Thinking cannot be disabled upstream (effort none or thinking disabled answers 400 code 2013), so the preview gets no effort map and no thinking toggle: none omits the field instead of sending a disabled value. It ignores reasoning_split and returns reasoning_content, so it stays off the split/details lists and replays as reasoning_content. The live /v1/models roster omits the preview, so the catalog retains it as a callable configured model, and a startup repair adds it to saved MiniMax rosters that are still the previous registry seed. No per-token price is published; metadata carries context and modalities without a cost.

- Around line 601-602: Remove the monthly subscription amounts from the
model-specific paragraph about preview usage in the Token Plan quota. Preserve
the explanation that OpenCodex shows no estimated cost because usage comes from
that quota.

MiniMax-M3.1-Flash-Previewon 2026-09-27. Before this change OpenCodex did not list it, and copying the MiniMax-M3 settings would have broken it: M3'sloweffort sendsthinking: {"type":"disabled"}, which this model rejects with HTTP 400 (code 2013, "requires adaptive thinking").After this change both

No request can disable thinking.reasoning_splitand always returnsreasoning_content, so it stays offreasoningSplitModels/reasoningDetailsModelsand prior thinking is replayed asreasoning_content.GET /v1/modelsdoes not list the preview yet, and the live roster would drop it. It is now a callable configured model inCALLABLE_CONFIGURED_COMPATIBILITY_MODELS, the same pattern Kimi and xAI use.stale-model-roster-migration.ts, runs in the existing repair pass beside the context-window and vision repairs. It replaces a savedminimax/minimax-cnroster only while that roster is byte-for-byte the previous seed, so a hand-edited list is left alone. It fills the added id's context window and default effort only inside records the row already has.Evidence: sources plus a live probe against
