CodeFuse-VLM
CodeFuse-VLM is a Multimodal LLM(MLLM) framework that provides users with multiple vision encoders, multimodal alignment adapters, and LLMs. Through CodeFuse-VLM framework, users are able to customize their own MLLM model to adapt their own tasks. As more and more models are published on Huggingface community, there will be more open-source vision encoders and LLMs. Each of these models has their own specialties, e.g. Code-LLama is good at code-related tasks but has poor performance for Chinese tasks. Therefore, we built CodeFuse-VLM framework to support multiple vision encoders, multimodal alignment adapters, and LLMs to adapt different types of tasks.
Under CodeFuse-VLM framework, we use cross attention multimodal adapter, Qwen-14B LLM, and Qwen-VL's vision encoder to train CodeFuse-VLM-14B model. On multiple benchmarks, our CodeFuse-VLM-14B shows superior performances over Qwen-VL and LLAVA-1.5.
Here is the table for different MLLM model's performance on benchmarks
| Model | MMBench | MMBench-CN | VqaV2 | GQA | TextVQA | Vizwiz |
|---|---|---|---|---|---|---|
| LLAVA-1.5 | 67.7 | 63.6 | 80.0 | 63.3 | 61.3 | 53.6 |
| Qwen-VL | 60.6 | 56.7 | 78.2 | 57.5 | 63.8 | 38.9 |
| CodeFuse-VLM-14B | 75.7 | 69.8 | 79.3 | 59.4 | 63.9 | 45.3 |

Multimodal Alignment
Please run sh scripts/pretrain.sh or sh scripts/pretrain_multinode.sh
Visual Instruction Tuning
Please run sh scripts/finetune.sh or sh scripts/finetune_multinode.sh
Evaluation
Please run python scripts in directory llava/eval/. Our pre-trained CodeFuse-VLM-14B can be loaded with the following code:
import os
from llava.model.builder import load_mixed_pretrained_model
model_path = '/pretrained/model/path'
tokenizer, model, image_processor, context_len = load_mixed_pretrained_model(model_path, None, 'qwen-vl-14b', os.path.join(model_path, 'Qwen-VL-visual'), 'cross_attn', os.path.join(model_path, 'mm_projector/mm_projector.bin'))
