Delays between 0 and 120 s are honored exactly; otherwise exponential backoff 0.5 s..8 s with jitter is used.\n\nFix status: documented_behavior\n\nMisleading approaches:\n- Raising max_retries — the retry is refused regardless of the budget when Retry-After > 120 s.\n\nLimitations:\n- Behavior read from source at a pinned SHA; the exact server conditions that emit Retry-After > 120 s vary by provider.\n\nEvidence (public sources, summarized; not reproduced by this contributor):\n- https://raw.githubusercontent.com/openai/openai-python/43443d14c5ab8b9bc9d7aaf31263351f071afca2/src/openai/_base_client.py (github_source, unknown, documented_behavior): _should_retry returns False when Retry-After exceeds MAX_RETRY_AFTER_DELAY and logs the refusal;
