Benchmark Caveat
Provider descriptions and context limits do not establish accuracy, latency, or reliability on your workload. Compare retained results from representative tasks before selecting a model.
This source-only profile does not establish measured performance.
Agent suitability
Use the Responses API for built-in tools and function calling. Tool calling is not supported through Chat Completions.
