What is Emu2-Chat?
Emu2-Chat is a 37-billion-parameter generative multimodal model from the Beijing Academy of AI (BAAI), released in December 2023. Unlike most multimodal AIs that only understand images, Emu2 can both understand AND generate images and text in one unified model — making it a pioneering research model for true multimodal generative AI.
It's released under permissive licensing for research and commercial use.
Why Emu2-Chat Is Trending in 2026
As multimodal AI matures toward unified architectures (à la GPT-4o), Emu2-Chat represents an important open-source counterpart with weights you can actually download. Its successor Emu3 (2024) extended the approach to native video generation in a single token space.
Key Features and Capabilities
Emu2-Chat supports visual question answering, image captioning, image generation from text, image editing through dialogue, multi-turn multimodal conversation, and few-shot in-context learning across modalities.
Who Should Use Emu2-Chat?
Emu2-Chat is built for multimodal AI researchers, generative AI experimenters, academic teams, and developers exploring unified vision-language generation.
Top Use Cases
Real-world applications include image generation with conversational refinement, multimodal research, in-context image editing, generative AI experiments, academic publications, and creative AI tools.
Where Can You Run It?
Emu2-Chat runs on Hugging Face Transformers and BAAI's official inference toolkit. The 37B model is heavy — needs ~74 GB VRAM at BF16 (2× A100 80GB) or ~22 GB at 4-bit quantization.
How to Use Emu2-Chat (Quick Start)
Load via Hugging Face: BAAI/Emu2-Chat with trust_remote_code. Pass interleaved text and image inputs. The model returns either text responses or generated images depending on the task.
When Should You Choose Emu2-Chat?
Choose Emu2-Chat for research into unified multimodal generative architectures. For production multimodal generation, use Stable Diffusion + LLaVA-NeXT pipelines or commercial GPT-4o.
Pricing
Emu2-Chat is free under BAAI's permissive license.
Pros and Cons
