Function calling lets AI invoke APIs, update databases, send notifications, and chain multi-step processes. Build complex automations that react intelligently to dynamic inputs.
JSON mode ensures structured, parseable output for downstream systems. Extract data from documents, classify content, and transform information at scale with reliable formatting.
Reasoning models analyze complex scenarios with chain-of-thought transparency. Ideal for approval workflows, anomaly detection, and automated decision trees that need to explain their logic.
Streaming enables real-time responses to incoming events. Process webhooks, handle live data feeds, and respond to triggers with minimal latency for time-sensitive workflows.
