# LobeChat

[LobeChat](https://lobehub.com/) is an open-source, modern-design ChatGPT/LLM UI. Connect it to TensorX using the OpenAI-compatible configuration.

## Prerequisites

* LobeChat installed (self-hosted or local)
* TensorX API key from [app.tensorx.ai](https://app.tensorx.ai)

## Configuration Options

### Option 1: Environment Variables (Recommended for Self-Hosted)

Set these environment variables when deploying LobeChat:

```bash
# Required
OPENAI_API_KEY=your-tensorx-api-key
OPENAI_PROXY_URL=https://api.tensorx.ai/v1

# Optional: Customize available models
OPENAI_MODEL_LIST=-all,+claude-sonnet-4-20250514,+gpt-4o,+gpt-4o-mini
```

### Option 2: UI Configuration

1. Open LobeChat Settings (gear icon)
2. Navigate to **AI Service Provider** > **OpenAI**
3. Configure:
   * **API Key**: Your TensorX API key
   * **API Proxy URL**: `https://api.tensorx.ai/v1`
4. Save settings

## Docker Deployment

Deploy LobeChat with TensorX configuration:

```yaml
# docker-compose.yml
version: '3.8'
services:
  lobe-chat:
    image: lobehub/lobe-chat
    ports:
      - "3210:3210"
    environment:
      - OPENAI_API_KEY=your-tensorx-api-key
      - OPENAI_PROXY_URL=https://api.tensorx.ai/v1
      - OPENAI_MODEL_LIST=-all,+claude-sonnet-4-20250514,+claude-3-5-sonnet-20241022,+gpt-4o,+gpt-4o-mini
```

Run with:

```bash
docker-compose up -d
```

## Vercel Deployment

When deploying to Vercel, set these environment variables in your project settings:

| Variable            | Value                                                 |
| ------------------- | ----------------------------------------------------- |
| `OPENAI_API_KEY`    | Your TensorX API key                                  |
| `OPENAI_PROXY_URL`  | `https://api.tensorx.ai/v1`                           |
| `OPENAI_MODEL_LIST` | `-all,+claude-sonnet-4-20250514,+gpt-4o,+gpt-4o-mini` |

## Model List Configuration

The `OPENAI_MODEL_LIST` environment variable controls available models:

* Use `+model-name` to add a model
* Use `-model-name` to hide a model
* Use `-all` to disable all default models first
* Use `model_name=Display Name` to customize display names

Example configurations:

```bash
# Only TensorX models
OPENAI_MODEL_LIST=-all,+claude-sonnet-4-20250514,+claude-3-5-sonnet-20241022,+gpt-4o,+gpt-4o-mini

# With custom display names
OPENAI_MODEL_LIST=-all,+claude-sonnet-4-20250514=Claude Sonnet 4,+gpt-4o=GPT-4o
```

## Available Models

See [TensorX Models](/api-reference/models.md) for all available models.

Popular choices for LobeChat:

| Model                        | Best For                         |
| ---------------------------- | -------------------------------- |
| `claude-sonnet-4-20250514`   | Complex conversations, analysis  |
| `claude-3-5-sonnet-20241022` | General chat, coding assistance  |
| `gpt-4o`                     | Multi-modal, image understanding |
| `gpt-4o-mini`                | Fast responses, cost-effective   |

## Troubleshooting

### Empty responses

Check that `OPENAI_PROXY_URL` includes `/v1` at the end.

### Models not appearing

Verify `OPENAI_MODEL_LIST` syntax:

* Each model should be prefixed with `+`
* Use commas without spaces to separate models

### Authentication errors

Ensure your TensorX API key is valid and has available credits.
