Bunny-Llama-3-8B-V: 🤗 v1.1 | 🤗 v1.0 | 🤗 v1.0-GGUF
Bunny-4B: 🤗 v1.1 | 🤗 v1.0 | 🤗 v1.0-GGUF
Bunny is a family of lightweight but powerful multimodal models. It offers multiple plug-and-play vision encoders, like EVA-CLIP, SigLIP and language backbones, including Llama-3-8B, Phi-3-mini, Phi-1.5, StableLM-2, Qwen1.5, MiniCPM and Phi-2. To compensate for the decrease in model size, we construct more informative training data by curated selection from a broader data source.
We are thrilled to introduce Bunny-Llama-3-8B-V, the pioneering vision-language model based on Llama-3, showcasing exceptional performance. The v1.1 version accepts high-resolution images up to 1152x1152.
Moreover, our Bunny-4B model built upon SigLIP and Phi-3-mini outperforms the state-of-the-art MLLMs, not only in comparison with models of similar size but also against larger MLLMs (7B and 13B). Also, the v1.1 version accepts high-resolution images up to 1152x1152.

Here we show a code snippet to show you how to use Bunny-v1.1-Llama-3-8B-V, Bunny-v1.1-4B, Bunny-v1.0-3B and so on with HuggingFace transformers.
This snippet is only used for above models because we manually combine some configuration code into a single file for users' convenience. For example, you can check modeling_bunny_llama.py and configuration_bunny_llama.py and their related parts in the source code of Bunny to see the difference. For other models including models trained by yourself, we recommend loading them with installing the source code of Bunny. Or you can copy files like modeling_bunny_llama.py and configuration_bunny_llama.py into your model and modify auto_map in config.json, but we can't guarantee its correctness and you may need to modify some code to fit your model.
Before running the snippet, you need to install the following dependencies:
pip install torch transformers accelerate pillowIf the CUDA memory is enough, it would be faster to execute this snippet by setting CUDA_VISIBLE_DEVICES=0.
Users especially those in Chinese mainland may want to refer to a HuggingFace mirror site.

Bunny training consists of two stages: (1) pretrain stage: use data to connect a frozen pretrained vision encoder to a frozen LLM, and only the connector is trained; (2) visual instruction tuning stage: use data to teach the model to follow multimodal instructions, where the connector, learnable LLM parameters and vision encoder (optional) are updated.
Bunny is trained on 8 A100 GPUs. Under other circumstances, you can reduce the per_device_train_batch_size and increase the gradient_accumulation_steps accordingly. Always keep the global batch size the same: global_batch_size  = per_device_train_batch_size gradient_accumulation_steps num_gpus.
Currently, we support several vision encoders and LLMs.
For vision encoders, we support CLIP, EVA-CLIP and SigLIP.

| siglip-so400m-patch14-384 | google/siglip-so400m-patch14-384 | 
For LLMs, we support phi-1.5, stablelm-2, qwen1.5-1.8b, minicpm, phi-2, phi-3 and llama3-8b.
| MODEL_TYPE | LLM | Download Link | 
|---|---|---|
| phi-1.5 | phi-1_5 | microsoft/phi-1_5 |

Data preparation We use a high-quality coreset with less duplicates and more informative samples of LAION-2B built by this work. We randomly sample 2 million image-text pairs from the coreset and convert them to training format. The dataset is available here. 
- 
Run Update --model_name_or_pathand--vision_towerto the paths of the LLM and vision encoder, respectively. UpdateMODEL_TYPEandOUTPUT_DIRaccordingly. The global batch size is 256. S$^2$ -Wrapper would be enabled if--use_s2 Trueadded.You may refer to the settings in our experiments in the Training Tutorial. sh script/train/pretrain.sh 
- 
Data preparation We build Bunny-695K by modifying SVIT-mix-665K for finetuning. And we then combine it with LLaVA-665K and ALLaVA-Instruct-4V, i.e., Bunny-LLaVA-1.4M, Bunny-ALLaVA-1.3M, and Bunny-LLaVA-ALLaVA-2M. The dataset is available here. If you only want to use Bunny-695K and the related images, you can just download them here. 
- 
Run Update --model_name_or_pathand--vision_towerto the paths of the LLM and vision encoder, respectively. UpdateMODEL_TYPE,PRETRAIN_DIRandOUTPUT_DIRaccordingly. The global batch size is 128. ForMODEL_TYPE = minicpm/phi-3/llama3-8b, change--versiontominicpm/phi3/llama, too. S$^2$ -Wrapper would be enabled if--use_s2 Trueadded. The vision encoder would be tuned if--unfreeze_vision_tower Trueadded.We explore a better strategy including more visual instruction tuning data, S $^2$ -Wrapper, trainable vision encoder, weight merging, and etc. You may refer to the settings in our experiments in the Training Tutorial.# full-parameter tuning sh script/train/finetune_full.sh # LoRA tuning sh script/train/finetune_lora.sh 
If you want to continuously fine-tuning our released Bunny models on your data or to adapt certain task,
expand to see the instructions.
- 
Prepare data: convert your data to a JSONfile of a list of all samples with the format like Bunny-695K.
- 
Prepare model: - 
download Bunny models and if only LoRA provided, merge the LoRA weights and base LLM python script/merge_lora_weights.py \ --model-path /path/to/bunny_lora_weights \ --model-base /path/to/base_llm_model \ --model-type phi-2 (or stablelm-2 or phi-1.5 or qwen1.5-1.8b or minicpm or phi-3 or llama3-8b) \ --save-model-path /path/to/merged_model 
- 
add "continuous_training": truein/path/to/merged_model/config.jsonto ensure loading the vision tower from merged weights
 
- 
- 
Edit script: both finetune_full.shandfinetune_lora.shcan be used, before:- 
change --model_name_or_pathto/path/to/merged_model
- 
delete --pretrain_mm_mlp_adapterbecause we load the cross-modality projector from merged weights
- 
customize the hyperparameters, e.g. the learning rate, to fit your dataset 
- 
for MODEL_TYPE = minicpm/phi-3/llama3-8b, change--versiontominicpm/phi3/llama, too. S$^2$ -Wrapper would be enabled if--use_s2 Trueadded. The vision encoder would be tuned if--unfreeze_vision_tower Trueadded.
 
- 
Note that if you continuously fine-tune Bunny models using LoRA, --model-base should be Bunny models rather than the original LLMs when loading.
- 
Starting the Controller First, start the controller. This service orchestrates communication between the web server and model workers. python -m bunny.serve.controller \ --host 0.0.0.0 \ --port 10000 
- 
Launching the Gradio Web Server To interact with the models through a web interface, start the Gradio web server. Basic start: python -m bunny.serve.gradio_web_server \ --controller http://localhost:10000 \ --model-list-mode reload If you want to share your web server with others, use --shareoption. Note thatfrpc_linux_amd64_v0.2may be missing and you can fix it following instructions printed on the screen and making the file executable.python -m bunny.serve.gradio_web_server \ --controller http://localhost:10000 \ --model-list-mode reload \ --share Now, you can open the web interface with the URL printed on the screen. You may notice that there is no model in the model list. Do not worry, as we have not launched any model worker yet. It will be automatically updated when you launch a model worker. 
- 
Launching Model Workers Model workers handle the processing of model inferences. Configure each worker with the appropriate model and start it. Note to check whether conv_modeis correct here which is decided by the name (path) of the model.- 
For full-parameter tuning models python -m bunny.serve.model_worker \ --host 0.0.0.0 \ --controller http://localhost:10000 \ --port 40000 \ --worker http://localhost:40000 \ --model-path /path/to/bunny/model \ --model-type phi-2 (or stablelm-2 or phi-1.5 or qwen1.5-1.8b or minicpm or phi-3 or llama3-8b) 
- 
For LoRA tuning models You can use script/merge_lora_weights.pyto merge the LoRA weights and base LLM, and use it as above.python script/merge_lora_weights.py \ --model-path /path/to/bunny_lora_weights \ --model-base /path/to/base_llm_model \ --model-type phi-2 (or stablelm-2 or phi-1.5 or qwen1.5-1.8b or minicpm or phi-3 or llama3-8b) \ --save-model-path /path/to/merged_model Or you can use it without merging as below. python -m bunny.serve.model_worker \ --host 0.0.0.0 \ --controller http://localhost:10000 \ --port 40000 \ --worker http://localhost:40000 \ --model-path /path/to/bunny_lora_weights \ --model-base /path/to/base_llm_model \ --model-type phi-2 (or stablelm-2 or phi-1.5 or qwen1.5-1.8b or minicpm or phi-3 or llama3-8b) 
 
- 
For CLI-based inference without using the Gradio interface, use the following command:
- 
For full-parameter tuning models python -m bunny.serve.cli \ --model-path /path/to/bunny/model \ --model-type phi-2 (or stablelm-2 or phi-1.5 or qwen1.5-1.8b or minicpm) \ --image-file /path/to/the/test/image \ --conv-mode bunny (change to minicpm/phi3/llama for model-type = minicpm/phi-3/llama3-8b)
- 
For LoRA tuning models You can use script/merge_lora_weights.pyto merge the LoRA weights and base LLM, and use it as above.python script/merge_lora_weights.py \ --model-path /path/to/bunny_lora_weights \ --model-base /path/to/base_llm_model \ --model-type phi-2 (or stablelm-2 or phi-1.5 or qwen1.5-1.8b or minicpm or phi-3 or llama3-8b) \ --save-model-path /path/to/merged_model Or you can use it without merging as below. python -m bunny.serve.cli \ --model-path /path/to/bunny_lora_weights \ --model-base /path/to/base_llm_model \ --model-type phi-2 (or stablelm-2 or phi-1.5 or qwen1.5-1.8b or minicpm or phi-3 or llama3-8b) \ --image-file /path/to/the/test/image \ --conv-mode bunny (change to minicpm/phi3/llama for model-type = minicpm/phi-3/llama3-8b)
You can also control temperature, repetition-penalty and max-new-tokens.
