Complex data pipelines
Generate structured JSON responses directly—ideal for API orchestration and log automation.
Long-content understanding
Process and output extensive content like full transcripts, reports, or novels in a single request.
Multimodal agents
Build agents that take text, visuals, audio, and video, and return unified structured data.
Cost-effective reasoning
Run high-throughput and chain-of-thought workflows with advanced JSON support at lower cost.
AI-assisted coding & analysis
Use structured outputs for formatted code, chart data, or config generation straight from prompt.
