Prerequisites
Batch processing introduces unique failure modes that require specific handling strategies.
Batch Failure Handling
When a batch completes, some requests may fail while others succeed. Handle failures by:
custom_id that correlates to the responseCritical Constraint: No Multi-Turn Tool Calling
The batch API does not support multi-turn tool calling within a single request. Since processing is asynchronous, there is no mechanism to:
This fundamentally breaks iterative tool-calling workflows. Batch is single-turn only.
Sample-First Strategy
Before batch-processing large volumes:
This maximizes first-pass success rates and avoids expensive iterative resubmission.
Key Takeaways
- ✓Resubmit only failed documents identified by custom_id, not the entire batch
- ✓Batch API is single-turn only -- no multi-turn tool calling
- ✓Test prompts on a sample set before batch-processing large volumes
- ✓Track failure patterns to fix root causes before resubmission
