ActionAI21 LabsUpdated September 2026
Which AI21 models are available?
Short answer: You can list models in AI21 Labs by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the AI21 Labs List Models action to a workflow, map its 0 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ
Questions about List Models.
What does the List Models action do in AI21 Labs?
Returns the current AI21 model catalog with context windows and pricing per model. Pin specific versions for reproducible production workflows; latest aliases float as AI21 ships new model generations.
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 AI21 Labs returns an error?
The run history shows the failed step with its input and the error message AI21 Labs returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.
Does List Models support batch operations?
Run List Models inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within AI21 Labs's rate limits.
