getMaxInputTokens

Input-token budget per model call. When the estimated input (schema + IR-lite text + page images) exceeds this, the document is split into page-level windows that each fit, extracted independently, and merged — so a large document never hard-fails on the provider's context limit. Defaults to 100000, a conservative value that fits common model context windows while leaving room for output; raise it for large-context models. A per-request maxInputTokens action parameter overrides it.
