Lee-W opened a new pull request, #72150:
URL: https://github.com/apache/airflow/pull/72150
Dags need a per-run token ceiling that can vary by environment, but
max_output_tokens and max_tool_calls were only reachable through the
non-templated response_kwargs dict. Promote both to first-class, templated
operator arguments, coerce the rendered string to a positive int before the
request goes out, and reject an invalid or non-positive value instead of
silently running with no ceiling. Also reject the same key being set both as an
argument and inside response_kwargs, so one silently wins.
OpenAI's Responses API has no monetary cost limit to expose, so this is a
token ceiling only -- for a cost cap, use
apache-airflow-providers-common-ai instead. Hitting max_output_tokens does
not fail the request; the response comes back incomplete with truncated output
text, which the previous 'may be empty' warning did not describe. Surface
incomplete_details.reason in the log message so operators can tell a
truncation apart from other non-completed statuses.
