How do I generate text with Writer's Palmyra models?

Short answer: You can chat completion in Writer by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Writer Chat Completion action to a workflow, map its 5 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 Chat Completion.

What does the Chat Completion action do in Writer?

Chat with Palmyra models from Writer, the enterprise content-generation platform tuned for brand voice, on-prem knowledge, and compliance use cases. OpenAI-compatible request shape.

What inputs does Chat Completion require?

Required: Model, User Message. Every input accepts a static value or a variable from any upstream node in your workflow.

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 Writer returns an error?

The run history shows the failed step with its input and the error message Writer 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 Chat Completion support batch operations?

Run Chat Completion 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 Writer's rate limits.
