Compare model APIs for agent workflows that need tool calling, JSON mode, long context, and budget policies.
Agent workflows are output-heavy and can become expensive quickly. Teams should compare tool calling, JSON support, context length, latency, and output price before routing agent tasks to a model.
Source basis: NextModel capability mapping and supported-parameter metadata when available.
Fit score
Start with the shortlist, then test real prompts and compare monthly cost before production routing.
