[BOT ISSUE] Mistral: add deprecation markers for retired pixtral-large-2411 and mistral-large-2411

[github-actions]

Summary

Two Mistral models were officially deprecated on February 27, 2026, and retired on May 31, 2026, but lack deprecation_date markers in the catalog. Both retirement dates have already passed (today is June 30, 2026). The pixtral-large-latest alias still points to the deprecated pixtral-large-2411.

Without the deprecation_date field, markModelsPastDeprecationDate() in packages/proxy/schema/models.ts will not auto-flag these as deprecated, and they will continue appearing as active models in the UI.

Affected Models

Model ID	Current deprecation_date	Correct Value	Deprecated	Retired	Line
pixtral-large-2411	(missing)	2026-05-31	2/27/2026	5/31/2026	~4344
mistral-large-2411	(missing)	2026-05-31	2/27/2026	5/31/2026	~4306

Both entries otherwise have correct pricing, format, and token limits. Only the deprecation marker is missing.

Note: pixtral-large-latest (line ~4331) still points to the deprecated pixtral-large-2411. Its pricing and metadata remain correct, but it may also warrant a deprecation marker since its target is retired.

Verification

Check	Status	Detail
Cross-source (deprecation)	✅	Mistral models index deprecation table lists both with "Deprecation: 2/27/2026, Retirement: 5/31/2026" AND official replacements (Mistral Medium 3.5 for both)
Already fixed	✅	Confirmed both entries lack deprecation_date in model_list.json
Retirement past	✅	5/31/2026 retirement date is 30 days ago
Duplicate check	✅	No open issue covers Mistral deprecation markers

Verification Notes

Field	Source	Notes
Deprecation date 2/27/2026	Mistral models index	Listed in the deprecation table
Retirement date 5/31/2026	Mistral models index	Both models share the same timeline
Replacement: Mistral Medium 3.5	Mistral models index	Official replacement for both

• packages/proxy/schema/models.ts — markModelsPastDeprecationDate() (line ~217) checks deprecation_date per entry
