EMOVA-Qwen-2.5-7B-HF

Model Summary

EMOVA (EMotionally Omni-present Voice Assistant) is a novel end-to-end omni-modal LLM that can see, hear and speak without relying on external models. Given the omni-modal (i.e., textual, visual and speech) inputs, EMOVA can generate both textual and speech responses with vivid emotional controls by utilizing the speech decoder together with a style encoder. EMOVA possesses general omni-modal understanding and generation capabilities, featuring its superiority in advanced vision-language understanding, emotional spoken dialogue, and spoken dialogue with structural data understanding. We summarize its key advantages as:

• State-of-the-art omni-modality performance: EMOVA achieves state-of-the-art comparable results on both vision-language and speech benchmarks simultaneously. Our best performing model, EMOVA-72B, even surpasses commercial models including GPT-4o and Gemini Pro 1.5.
• Emotional spoken dialogue: A semantic-acoustic disentangled speech tokenizer and a lightweight style control module are adopted for seamless omni-modal alignment and diverse speech style controllability. EMOVA supports bilingual (Chinese and English) spoken dialogue with 24 speech style controls (i.e., 2 speakers, 3 pitches and 4 emotions).
• Diverse configurations: We open-source 3 configurations, EMOVA-3B/7B/72B, to support omni-modal usage under different computational budgets. Check our Model Zoo and find the best fit model for your computational devices!

Usage

This repo contains the EMOVA-Qwen2.5-7B checkpoint organized in the HuggingFace format, and thus, can be directly loaded with transformers Auto APIs.

from transformers import AutoModel, AutoProcessor
from PIL import Image

### Uncomment if you want to use Ascend NPUs
# import torch_npu
# from torch_npu.contrib import transfer_to_npu
