Claude Sonnet 4.5 (batch)

Claude Sonnet 4.5 in batch mode, Anthropic's mid-tier model optimized for coding and agentic workflows with a 1M-token context window.

Strengths

Strong performance on coding benchmarks and tasks requiring real-world agent autonomy, with a very large context window for processing extended code repositories and multi-file workflows.

Best for

Asynchronous batch processing of coding tasks, software engineering workflows, and agentic work where latency is not a concern.

Limitations

Designed for non-real-time processing only; for synchronous workloads use the standard Claude Sonnet 4.5 release, and for more capable autonomous agents consider Claude Opus 4.8.
