Stay tuned for the updates!

Brief Introduction

It is recommended to check out our papers for technical details.

💬 What can SEED-LLaMA do?

SEED-LLaMA is capable of both multimodal comprehension and generation, exhibiting compositional emergent abilities such as multi-turn in-context multimodal generation, acting like your AI assistant. [Compare to SOTA] [More examples on X]

💡 How does SEED-LLaMA achieve it?

The core of SEED-LLaMA is the tailored SEED tokenizer, which properly quantized visual signals into discrete visual tokens, capturing necessary semantics while being produced under 1D causal dependence. [SEED-2 vs. SEED-1]

Usage

Dependencies

• Python >= 3.8 (Recommend to use Anaconda)
• PyTorch >= 1.11.0
• NVIDIA GPU + CUDA

Installation

Clone the repo and install dependent packages

git clone https://github.com/AILab-CVC/SEED.git
cd SEED
pip install -r requirements.txt

Model Weights

We release the pretrained SEED Tokenizer and De-Tokenizer, pretrained and instruction tuned SEED-LLaMA-8B and SEED-LLaMA-14B in SEED Hugging Face.

• Check the SEED tokenizer weights in AILab-CVC/seed-tokenizer-2
• Check the SEED LLaMA(8B) weights in AILab-CVC/seed-llama-8b-sft
• Check the SEED LLaMA(14B) weights in AILab-CVC/seed-llama-14b-sft

The model weights of unCLIP SD-UNet which are used to reconstruct the image will be downloaded automatically.

Inference for visual tokenization and de-tokenization

To discretize an image to 1D visual codes with causal dependency, and reconstruct the image from the visual codes using the off-the-shelf unCLIP SD-UNet:

cd ..   # SEED/ 
python scripts/seed_tokenizer_inference.py

Inference for SEED-LLaMA

Given that SEED-LLaMA-8B is based on Vicuna-7B and SEED-LLaMA-14B based on LLaMA2-Chat-13B, we use Vicuna-7B's ("USER:", "ASSISTANT:") and LLaMA2-Chat-13B's ([INST] [/INST]) prompts for respective instruction tuning.

# Inference for SEED-LLaMA-8B
python scripts/seed_llama_inference_8B.py

# Inference for SEED-LLaMA-14B
python scripts/seed_llama_inference_14B.py

Launching Gradio Demo of SEED-LLaMA-14B Locally

1. Building the local demo of SEED-LLaMA-14B currently requires single 24GB GPU.

# SEED/
# in first terminal
bash scripts/start_backend_14b.sh
# in second terminal
bash scripts/start_frontend_14b.sh

2. Building the local demo of SEED-LLaMA-8B currently requires single 16GB GPU.

# SEED/
# in first terminal
bash scripts/start_backend_8b.sh
# in second terminal
bash scripts/start_frontend_8b.sh

Then the demo can be accessed through http://127.0.0.1:80
