## Step 2: Choose a Model

We provide multiple AI models to choose from. Visit the [Model Market](https://gccai.heqingsong.uk/en/model) to browse all available models and their pricing.

### Text Generation Models

* **GPT-4o**: Powerful dialogue and text generation capabilities
* **Claude**: High-performance conversational model by Anthropic
* **Gemini**: Google's multimodal large language model

### Image Generation Models

* **GPT-4o-image**: High‑quality image generation

### Video Generation Models

* **Sora2**: Professional video generation

## Step 3: Send a Request

### Text generation example

```bash theme={null}
curl -X POST https://gccai.heqingsong.uk/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-4o",
    "messages": [
      {
        "role": "user",
        "content": "Hello, please introduce yourself"
      }
    ]
  }'
```

### Image generation example

```bash theme={null}
curl -X POST https://gccai.heqingsong.uk/v1/images/generations \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-4o-image",
    "prompt": "A cute panda",
    "size": "1:1",
    "n": 1
  }'
```

### Video generation example

```bash theme={null}
curl -X POST https://gccai.heqingsong.uk/v1/videos/generations \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "sora-2",
    "prompt": "Waves crashing against the shore",
    "duration": 15,
    "aspect_ratio": "16:9"
  }'
```

## Step 4: Check Task Status

Because we use asynchronous processing, you need to query task status to obtain results.

```bash theme={null}
curl -X GET https://gccai.heqingsong.uk/v1/tasks/YOUR_TASK_ID \
  -H "Authorization: Bearer YOUR_API_KEY"
```
