Best agent model APIs for tool-calling workflows

Compare model APIs for agents that need tools, JSON mode, long context, and a budget you can live with.

Para que sirve esta lista corta?: Agent models

Agent runs spit out a lot of tokens and burn money when tool loops go wrong. Before you wire one up, check tool calling, JSON reliability, context length, latency, and output price. Then set a budget so a bad loop cannot empty the account overnight.

FAQ

Agent models FAQ

Which capabilities matter most for agent models?

Tool calling, structured JSON, enough context for the task, and instructions that stick. Everything else is secondary.

Why do agent workflows get expensive so fast?

They generate long traces: planning text, tool results stuffed back into context, and retries. Cap steps and log token use per run.

Should agents always use the strongest model?

No. Route planning or simple tool picks to cheaper models when quality allows, and reserve stronger models for hard steps.
