Summary
mistral-small-2501, mistral-saba-2502, and mistral-saba-latest were officially deprecated and retired by Mistral, but none of the three catalog entries has a deprecation_date or deprecated field. Without these, markModelsPastDeprecationDate() in models.ts will not flag them and they continue appearing as active models.
All three models were replaced by Mistral Small 4 (v26.03). The retirement dates are 8–10 months ago.
