Reason: Refresh MiniMax text model choices and defaults to the verified MiniMax-M3.1-Flash and MiniMax-M3 routes.

• Make MiniMax-M3.1-Flash the default for both global and China presets, followed by MiniMax-M3.
• Refresh Flash model metadata with the verified context, output, pricing, modalities, and reasoning defaults.
• Update stale roster migration and callable catalog retention for the current Flash identifier while preserving explicit saved and custom model selections.
• Regenerate the checked-in model metadata source output and update focused provider tests.

Walkthrough

The MiniMax model ID changes from MiniMax-M3.1-Flash-Preview to MiniMax-M3.1-Flash in metadata, compatibility hints, provider defaults, and roster migration. Its metadata gains output-limit and cost values, and its seeded input modalities add video.

Changes: MiniMax M3.1 Flash model update

Layer / File(s)	Summary
Model metadata and seed scripts/model-metadata.source.json, src/providers/registry/model-seeds.ts, src/codex/catalog/model-hints.ts	The global and China metadata entries use MiniMax-M3.1-Flash, retain a 1,000,000-token context window, and add a 524,288-token output limit and cost values. The seed adds video input. Compatibility hints use the renamed model ID.
Provider defaults and roster repair src/providers/registry/entries-extended.ts, src/providers/stale-model-roster-migration.ts	Both MiniMax Coding Plan entries use the renamed model constant as the default and reasoning-effort key. The stale-roster migration seeds the renamed model with its context window and default reasoning effort.
Registry and seed tests tests/providers/minimax-combo-image-input.test.ts, tests/providers/minimax-reasoning-split.test.ts, tests/providers/model-roster-seed-repair.test.ts, tests/providers/provider-registry-parity.test.ts	Tests use the renamed model ID. Assertions cover video input, registry defaults, context size, and reasoning-effort metadata.

Priority: Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Suggested labels: enhancement

Merge Risk: Moderate · up to 17f3d

Users with saved MiniMax configurations that name the retired preview model may keep a selection the registry no longer provides. Repaired rosters may also lack Flash's output limit in routed requests. Add a preview-to-Flash rename migration and seed the output limit before merging.

Add a MiniMax preview-model rename migration.

MODEL_RENAMES has no entry for MiniMax-M3.1-Flash-Preview. Therefore, startup leaves that ID in saved model lists, defaults, and model-keyed metadata. The stale-roster migration also does not match a roster containing that ID because it only accepts the eight-model from roster. Existing configurations can retain a model selection that the registry no longer seeds.

Add the rename for both MiniMax providers and cover the saved fields with a regression test.

🐛 Suggested fix

 export const MODEL_RENAMES: readonly ModelRename[] = [
+  ...(["minimax", "minimax-cn"] as const).map(provider => ({
+    provider,
+    from: "MiniMax-M3.1-Flash-Preview",

Seed MiniMax-M3.1-Flash's output limit during roster repair.

A partial saved modelMaxOutputTokens map remains without MiniMax-M3.1-Flash because the MiniMax migration entry supplies no maxOutputTokens. The catalog path falls back to generated metadata, but the effective routed policy reads the saved and registry maps, and MiniMax has no registry output-limit fallback. Add the 524,288 limit to the migration entry.

Release decision (v2.93.0 dev-merge, maintainer triage lane): CARRIED to dev as #7746, merged in 609ce90. This PR targets main, which only moves by release promotion, so it couldn't merge as is. The carry keeps your commit and authorship, and the squash commit names you with Co-authored-by.

The carry also fixes both open CodeRabbit threads. Saved MiniMax-M3.1-Flash-Preview selections are renamed to the GA id at startup, through a MODEL_RENAMES entry on both presets. Roster repair now seeds the 524,288 output limit into partial output maps. It differs from your version in one way: Flash's registry input modalities stay text/image, like M3, because the registry keeps video off Codex's input enum.

Closing in favour of #7746. Thank you for the refresh.
