Documented steps

  1. GET http://localhost:11434/api/ps.
  2. Response: {"models": [{"name", "model", "size", "digest", "details": {...}, "expires_at": "<RFC3339>", "size_vram": <bytes>}]}.
  3. expires_at is when the model will be unloaded if idle (driven by keep_alive).
  4. Judge GPU placement by comparing size_vram to size: size_vram == size means fully on GPU; size_vram == 0 means fully in CPU RAM; in between means a partial (split) load.
  5. An empty models array means nothing is currently loaded — the next generate/chat pays the model load cost (visible as load_duration in that response).
