Which Claude models are available?

FAQ

Questions about List Models.

What does the List Models action do in Anthropic?
Lists available Claude models with their display names and context windows. Used to populate a dynamic model picker.
What inputs does List Models require?
List Models has no required inputs. Sensible defaults are applied if you leave fields blank.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if Anthropic returns an error?
The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.
Does List Models support batch operations?
Yes. Run List Models inside a Loop node to process arrays. TinyCommand handles Anthropic's rate limits automatically so you don't have to throttle manually.
