Developers can control the model's reasoning effort and use its long context window to carry information across substantial tasks. Tool calling uses the Responses API, allowing an application to connect model decisions to external tools rather than treating generated text as an action by itself.
Terra is useful for high-volume workflows where response speed and operating cost matter alongside task quality. The official model reference documents its supported interfaces, token limits, and pricing, helping teams build integrations around explicit capabilities instead of assuming every modality or endpoint is available.
