# LLaVA-RLHF Model Card

## Model details

**Model type:**
LLaVA-RLHF represents a novel aligned end-to-end trained large multimodal model that combines a CLIP vision encoder and Vicuna for general-purpose visual and language understanding, achieving impressive visual reasoning and perception capabilities mimicking spirits of the multimodal GPT-4.
Via Factually Augmented RLHF, LLaVA-RLHF is presented to be more helpful and less hallucinated than LLaVA or other open-sourced LMMs.

**Usage:**
**NOTE: The RLHFed model is trained with LoRA and the bfloat16 data type.**
Users have to apply the PEFT-LoRA on the LLaVA-SFT+ model.

```python
dtype = torch.bfloat16
model_path = "LLaVA-RLHF-7b-v1.5-224/sft_model"
lora_path = "LLaVA-RLHF-7b-v1.5-224/rlhf_lora_adapter_model"
model = LlavaLlamaForCausalLM.from_pretrained(
    model_path,
    device_map={"": "cuda:0"},
    torch_dtype=dtype,
)
model = PeftModel.from_pretrained(
    model,
    lora_path,
)
```

**Model date:**
LLaVA-RLHF was trained in Sept 2023.
