# MiDashengLM-7B-0804 (4bit, GPTQ quantized)

The 4bit (w4a16) weights for [mispeech/midashenglm-7b-0804-fp32](https://huggingface.co/mispeech/midashenglm-7b-0804-fp32), quantized by GPTQ.

An ideal choice for resource-constrained environments. It offers broad GPU compatibility and a smaller memory footprint, making it suitable for deployment where VRAM, memory, or storage is limited, provided that a slight trade-off in quality is acceptable.

## Usage

### Load Model

```python
from transformers import AutoModelForCausalLM, AutoProcessor, AutoTokenizer

model_id = "mispeech/midashenglm-7b-0804-w4a16-gptq"
model = AutoModelForCausalLM.from_pretrained(model_id, trust_remote_code=True)
tokenizer = AutoTokenizer.from_pretrained(model_id)
processor = AutoProcessor.from_pretrained(model_id, trust_remote_code=True)
```

### Construct Prompt

```python
user_prompt = "Caption the audio."  # You may try any other prompt

messages = [
    {
        "role": "user",
        "content": [
            {"type": "text", "text": user_prompt},
            {
                "type": "audio",
                "path": "/path/to/example.wav",
                # or "url": "https://example.com/example.wav"
                # or "audio": np.random.randn(16000)
            },
        ],
    },
]
```

### Generate Output

```python
import torch

with torch.no_grad():
    model_inputs = processor.apply_chat_template(
        messages,
        tokenize=True,
        add_generation_prompt=True,
        add_special_tokens=True,
        return_dict=True,
    ).to(device=model.device, dtype=model.dtype)
    generation = model.generate(**model_inputs)
    output = tokenizer.batch_decode(generation, skip_special_tokens=True)  # ["An engine is idling."]
```
