# Supported base models

> Hugging Face base models Loops accepts, with sequence-length limits.

Each row below is a Hugging Face repo ID you can pass as `base_model` when starting a Loops run, along with the maximum supported sequence length. Baseten adds rows as new models are validated end to end.

## Models

## Pass a model to Loops

Pass the table value verbatim as `base_model` through any of the following entry points:

* The Python SDK, via `tinker.ServiceClient.create_lora_training_client(base_model=...)`. See the [Loops quickstart](/loops/quickstart).
* The HTTP API, via [`POST /v1/loops/runs`](/reference/loops-api/runs/create-a-run).
* The CLI, via `truss loops push <base_model>`, which provisions a session, run, and paired sampler in one call.

The minimal HTTP call provisions a run and its paired sampler against an existing session. Replace `sess_xyz789` with the `session.id` returned by `POST /v1/loops/sessions`:

```bash theme={"system"}
curl --request POST \
  --url https://api.baseten.co/v1/loops/runs \
  --header "Authorization: Bearer $BASETEN_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
    "session_id": "sess_xyz789",
    "base_model": "Qwen/Qwen3.5-9B"
  }'
```

For the full request body, response shape, and an interactive playground, see [`POST /v1/loops/runs`](/reference/loops-api/runs/create-a-run) in the Loops API reference.
