# 🏭 TRL Jobs

**TRL Jobs** is a simple wrapper around [Hugging Face Jobs](https://huggingface.co/docs/huggingface_hub/guides/jobs) that makes it easy to run [TRL](https://huggingface.co/docs/trl/) (Transformer Reinforcement Learning) workflows directly on 🤗 Hugging Face infrastructure.

Think of it as the quickest way to kick off **Supervised Fine-Tuning (SFT)** and more, without worrying about all the boilerplate setup.

## 📦 Installation

Get started with a single command:

```bash
pip install trl-jobs
```

## ⚡ Quick Start

Run your first supervised fine-tuning job in just one line:

```bash
trl-jobs sft --model_name Qwen/Qwen3-0.6B --dataset_name trl-lib/Capybara
```

The training is tracked with [Trackio](https://huggingface.co/docs/trackio/index) and the fine-tuned model is automatically pushed to the 🤗 Hub.

## 🛠 Available Commands

Right now, **SFT (Supervised Fine-Tuning)** is supported. More workflows will be added soon!

### 🔹 SFT (Supervised Fine-Tuning)

```bash
trl-jobs sft --model_name Qwen/Qwen3-0.6B --dataset_name trl-lib/Capybara
```

#### Required arguments

* `--model_name` → Model to fine-tune (e.g. `Qwen/Qwen3-0.6B`)
* `--dataset_name` → Dataset to train on (e.g. `trl-lib/Capybara`)

#### Optional arguments

* `--peft` → Use [PEFT (LoRA)](https://huggingface.co/docs/peft) (default: `False`)
* `--flavor` → Hardware flavor (default: `a100-large`, only option for now)
* `--timeout` → Max runtime (`1h` by default). Supports `s`, `m`, `h`, `d`
* `-d, --detach` → Run in background and print job ID
* `--namespace` → Namespace where the job will run (default: your user namespace)
* `--token` → Hugging Face token (only needed if not logged in)

➡️ You can also pass **any arguments supported by `trl sft`**. E.g.

```bash
trl-jobs sft --model_name Qwen/Qwen3-0.6B --dataset_name trl-lib/Capybara --learning_rate 3e-5
```

For the full list, see the [TRL CLI docs](https://huggingface.co/docs/trl/en/clis).

#### Dataset format

SFT supports various 4 dataset formats.

* Standard language modeling

```python
  example = {"text": "The sky is blue."}
  ```

* Standard prompt-completion

```python
  example = {"prompt": "The sky is", "completion": " blue."}
  ```

* Conversationanl language modeling

```python
    example = {"messages": [
        {"role": "user", "content": "What color is the sky?"},
        {"role": "assistant", "content": "It is blue."}
    ]}
    ```

* Conversational prompt-completion

```python
    example = {"prompt": [{"role": "user", "content": "What color is the sky?"}],
               "completion": [{"role": "assistant", "content": "It is blue."}]}
    ```

> [!IMPORTANT]
> When using conversational dataset, ensure that the model has a chat template.

> [!NOTE]
> When using prompt-completion dataset, the loss is only computed on the completion part.

For more details, see the [TRL docs - Dataset formats](https://huggingface.co/docs/trl/en/dataset_formats#language-modeling).
