getMaxParallelCalls

Maximum number of windowed extraction calls to run concurrently. Only applies when a large document is split into page-level windows (see ); each window is an independent VLM call, so running several at once is a large wall-clock win. Defaults to 4 — a balance between throughput and provider rate limits; raise it for large-context keys, lower it (or set 1 for fully sequential) if you hit rate limits. A per-request maxParallelCalls action parameter overrides it.
