+### ✨ New Features
+
+- **feat(blackbox):** refresh provider model catalog with latest models. (thanks @ptkelanatechsolutions)
+
 ### 🔧 Bug Fixes
 
 - **fix(executors): strip `client_metadata` from forwarded body for Cerebras and Mistral** — Cerebras returns 400 (`wrong_api_format`) and Mistral returns 422 (`extra_forbidden`) when the passthrough body carries `client_metadata` (an OpenAI Codex / Claude CLI field with no equivalent on these upstreams). The default executor now drops it for these two providers before sending downstream; other providers (notably `openai`/`codex`) keep it. (thanks @saurabh321gupta)
