Open WebUI

Self-hosted ChatGPT-style UI with native OpenAI connections.

Open WebUI lets admins add multiple OpenAI-compatible connections. Add FreeTheAi and the model picker auto-fills from /v1/models.

Recommended aliases

See the full live catalog at /models. Aliases are stable; pricing on the free tier stays $0.

Heads up

FreeTheAi can return thousands of `fth/` aliases on broader keys. Use Open WebUI's model filter or pick a curated key if the dropdown gets noisy.
Open WebUI also has a separate Ollama connection list. Make sure you add to OpenAI API, not Ollama.
