api: "GET /v1/api/llm-models/call-flow-models"
description: "List the language models currently available to your workspace."

> **For AI agents:** the complete documentation index is at [llms.txt](https://docs.trillet.ai/llms.txt). Append `.md` to any page URL for its markdown version.

Returns every language model your workspace can use, so you can pass a valid `id` as `llmModel` when creating or updating a call agent.

The available models change over time. Read this endpoint rather than hardcoding a list.
