  # Optional: total input context window, used as the denominator for the
  # context-usage ring and to trigger auto-summarization. You normally do NOT
  # need this — for models litellm can map (most OpenAI / Anthropic models) the
  # window is resolved automatically. Only set it when your model is served
  # through a proxy / self-hosted endpoint that litellm cannot map, so the ring
  # has no denominator. Scalar applies to the default model:
  # context_window: 200000
  # Or per-model (wins over the scalar); keys are matched by model name:
  # context_window_overrides:
  #   gpt-5.4: 400000
  #   claude-sonnet-4.5: 200000
