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.

Quickstart

HuggingFace transformers

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 pillow

If 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.

Training

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 $\times$ gradient_accumulation_steps $\times$ num_gpus.

Support Models

Currently, we support several vision encoders and LLMs.

For vision encoders, we support CLIP, EVA-CLIP and SigLIP.

Note that there are many variants of above models. We build and test our code based on the exact versions mentioned above. More models will be supported in the future!

Pretrain

  • 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_path and --vision_tower to the paths of the LLM and vision encoder, respectively. Update MODEL_TYPE and OUTPUT_DIR accordingly. The global batch size is 256. S$^2$-Wrapper would be enabled if --use_s2 True added.

    You may refer to the settings in our experiments in the Training Tutorial.

    sh script/train/pretrain.sh

Visual Instruction Tuning

  • 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_path and --vision_tower to the paths of the LLM and vision encoder, respectively. Update MODEL_TYPE, PRETRAIN_DIR and OUTPUT_DIR accordingly. The global batch size is 128. For MODEL_TYPE = minicpm/phi-3/llama3-8b, change --version to minicpm/phi3/llama, too. S$^2$-Wrapper would be enabled if --use_s2 True added. The vision encoder would be tuned if --unfreeze_vision_tower True added.

    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.

Continuous Fine-tuning

If you want to continuously fine-tuning our released Bunny models on your data or to adapt certain task,

expand to see the instructions.

  1. Prepare data: convert your data to a JSON file of a list of all samples with the format like Bunny-695K.

  2. 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": true in /path/to/merged_model/config.json to ensure loading the vision tower from merged weights

  3. Edit script: both finetune_full.sh and finetune_lora.sh can be used, before:

    • change --model_name_or_path to /path/to/merged_model

    • delete --pretrain_mm_mlp_adapter because 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 --version to minicpm/phi3/llama, too. S$^2$-Wrapper would be enabled if --use_s2 True added. The vision encoder would be tuned if --unfreeze_vision_tower True added.

Note that if you continuously fine-tune Bunny models using LoRA, --model-base should be Bunny models rather than the original LLMs when loading.

Demo

Gradio Web UI

  • 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 --share option. Note that frpc_linux_amd64_v0.2 may 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_mode is 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.py to 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)

CLI Inference (Without Gradio Interface)

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.py to 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.
