Agent guide

Best AI models for agents

This page prioritizes models with tool use and structured output support because those signals matter most for automations, task routing, and production agent behavior.

Fast answer

Start with the live shortlist, then validate the route

Agent stacks need reliable action calls and predictable output formats. Those features usually matter more than raw model popularity when you build repeatable workflows.

Data source and freshness

Catalog-backed, not a static price sheet

TVP refreshes this page from the live OpenRouter model catalog. This render used 587 public model records and was synchronized Sep 11, 2026, 6:28 AM UTC. Pricing, availability, and context values can change.

Verify the exact route before sending production traffic, then use the linked model and provider pages as the source for current values. Read the TVP data methodology.

FAQ

What buyers usually ask

Why are tools and structured output the main signals here?

Agent stacks need reliable action calls and predictable output formats. Those features usually matter more than raw model popularity when you build repeatable workflows.

Can an agent model also be a good coding model?

Yes. Many strong coding models also do well in agents because both workloads benefit from reasoning, tool use, and larger context windows.
