# Launching Chat

> Start the chat interface to test your models

# Launching the Chat Interface

The Chat interface lets you interact with your trained models in a browser.

## Quick Start

```bash theme={null}
aitraining chat
```

The browser will open automatically to `http://localhost:7860/inference`.

## Command Options

```bash theme={null}
aitraining chat [OPTIONS]

Options:
  --port PORT    Port to run on (default: 7860)
  --host HOST    Host to bind to (default: 127.0.0.1)
```

### Examples

```bash theme={null}
# Default (localhost:7860)
aitraining chat

# Custom port
aitraining chat --port 3000

# Accessible from other machines
aitraining chat --host 0.0.0.0 --port 7860
```

## Requirements

Before launching, you need:

* A trained model (local path or Hugging Face model ID)
* Sufficient memory to load the model

## Typical Workflow

1. Train a model:
   ```bash theme={null}
   aitraining llm --train \
     --model meta-llama/Llama-3.2-1B \
     --data-path ./my-data \
     --project-name my-model
   ```

2. Launch chat:
   ```bash theme={null}
   aitraining chat
   ```

3. Browser opens automatically to `localhost:7860/inference`

4. Load your trained model from `./my-model`

5. Start chatting

## Stopping the Server

Press `Ctrl+C` in the terminal to stop the chat server.

## Troubleshooting

<AccordionGroup>
  <Accordion title="Port already in use">
    Another process is using port 7860. Either:

    * Stop the other process
    * Use a different port: `aitraining chat --port 3000`
  </Accordion>

  <Accordion title="Model won't load">
    Check:

    * Model path is correct
    * Sufficient GPU/RAM memory
    * Model format is compatible (Hugging Face format)
  </Accordion>

  <Accordion title="Can't access from other machines">
    Use `--host 0.0.0.0` to bind to all interfaces:

    ```bash theme={null}
    aitraining chat --host 0.0.0.0
    ```
