Llm Models Models Summary Retrieve

GET/POST /api/models/summary/ (Public API — **auth optional**) GET/POST /api/llm_models/models/summary/ (Platform) Summary counts for LLM models. **Auth is optional** — same model as ``ModelsListView``: - **Unauthenticated** → counts over managed/global models only (``organization=null``). Rate-limited per client IP. - **API key / JWT** → counts include the caller's custom models too. Read-only: only GET (and POST-as-filter, delegating to GET). No write path. Returns: { "summary": { "total_count": 150, "global_count": 120, "custom_count": 30 } }
