WeMM

[📖中文版本] [🤗 HuggingFace]

WeMM is the most recent version of the multimodal large language model introduced by WeChatCV. Capable of engaging in Chinese-English bilingual conversations alongside dynamic high-resolution images, WeMM stands as the most powerful model with 10 billion parameters in the multimodal large language model rankings. Its overall evaluation score (Avg Rank) places it within the top tier. (Refer to vlm_leaderboard)

Inference

Feel free to visit our github for more execution code.

The following code will initiate an interactive interface that allows users to input an image path and prompt to receive a response from WeMM.

• WeMM-1.2（VL）

import torch
from PIL import Image
from transformers import AutoModel, GenerationConfig

model_path = 'feipengma/WeMM' # the path to the model 
wemm = AutoModel.from_pretrained(model_path, torch_dtype=torch.bfloat16, trust_remote_code=True)
wemm.cuda()
wemm.eval()

query = 'Describe this image.'
image = 'path/to/your/image'
pred = wemm.mm_generate(image, query)

• WeMM-Chat-CN

import torch
from PIL import Image
from transformers import AutoModel, GenerationConfig

model_path = 'feipengma/WeMM-Chat-CN'
wemm = AutoModel.from_pretrained(model_path, torch_dtype=torch.bfloat16, trust_remote_code=True)
wemm.cuda()
wemm.eval()

query = 'Why is the ocean blue?'
image = 'path/to/your/image'
pred = wemm.mm_generate(image, query)

• WeMM-Chat-2K-CN

import torch
from PIL import Image
from transformers import AutoModel, GenerationConfig

model_path = 'feipengma/WeMM-Chat-2k-CN'
wemm = AutoModel.from_pretrained(model_path, torch_dtype=torch.bfloat16, trust_remote_code=True)
wemm.cuda()
