MiniMax-VL-01

1. Introduction

We are delighted to introduce our MiniMax-VL-01 model. It adopts the "ViT-MLP-LLM" framework, which is a commonly used technique in the field of multimodal large language models. The model is initialized and trained with three key parts: a 303-million-parameter Vision Transformer (ViT) for visual encoding, a randomly initialized two-layer MLP projector for image adaptation, and the MiniMax-Text-01 as the base LLM. MiniMax-VL-01 has a notable dynamic resolution feature. Input images are resized per a pre-set grid, with resolutions from 336×336 to 2016×2016, keeping a 336×336 thumbnail. The resized images are split into non-overlapping patches of the same size. These patches and the thumbnail are encoded separately and then combined for a full image representation. The training data for MiniMax-VL-01 consists of caption, description, and instruction data. The Vision Transformer (ViT) is trained on 694 million image-caption pairs from scratch. Across four distinct stages of the training pipeline, a total of 512 billion tokens are processed, leveraging this vast amount of data to endow the model with strong capabilities. Finally, MiniMax-VL-01 has reached top-level performance on multimodal leaderboards, demonstrating its edge and dependability in complex multimodal tasks.

3. Quickstart

Here we provide a simple example of loading the tokenizer and model to generate content.

python

from transformers import AutoModelForCausalLM, AutoProcessor, AutoConfig, QuantoConfig, GenerationConfig
import torch
import json
import os
from PIL import Image

# load hf config
hf_config = AutoConfig.from_pretrained("MiniMaxAI/MiniMax-VL-01", trust_remote_code=True)

# quantization config, int8 is recommended
quantization_config =  QuantoConfig(
            weights="int8",
            modules_to_not_convert=[
                "vision_tower",
                "image_newline",
                "multi_modal_projector",
                "lm_head",
                "embed_tokens",
            ] + [f"model.layers.{i}.coefficient" for i in range(hf_config.text_config.num_hidden_layers)]
            + [f"model.layers.{i}.block_sparse_moe.gate" for i in range(hf_config.text_config.num_hidden_layers)]
        )

# set device map
model_safetensors_index_path = os.path.join("MiniMax-VL-01", "model.safetensors.index.json")

        new_key = key.replace('.weight','').replace('.bias','')
        if new_key not in vision_map:
            vision_map[new_key] = value
# assume 8 GPUs
world_size = 8

    'language_model.model.embed_tokens': 'cuda:0',
    'language_model.model.norm': f'cuda:{world_size - 1}',

for key, value in vision_map.items():
    device_map[key] = f'cuda:0'
device_map['vision_tower.vision_model.post_layernorm'] = f'cuda:0'

    for j in range(layers_per_device):
        device_map[f'language_model.model.layers.{i * layers_per_device + j}'] = f'cuda:{i}'

# load processor

prompt = processor.tokenizer.apply_chat_template(
    messages, tokenize=False, add_generation_prompt=True
)
raw_image = Image.open("figures/image.jpg")
# tokenize and move to device
model_inputs = processor(images=[raw_image], text=prompt, return_tensors='pt').to('cuda').to(torch.bfloat16)

# load bfloat16 model, move to device, and apply quantization
quantized_model = AutoModelForCausalLM.from_pretrained(
    "MiniMaxAI/MiniMax-VL-01",
    torch_dtype="bfloat16",

    eos_token_id=200020,
    use_cache=True,

# generate response
generated_ids = quantized_model.generate(**model_inputs, generation_config=generation_config)
print(f"generated_ids: {generated_ids}")
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
