The salient multimodal capabilities and interactive experience of GPT-4o
highlight its critical role in practical applications, yet it lacks a
high-performing open-source counterpart. In this paper, we introduce
Baichuan-Omni, the first open-source 7B Multimodal Large Language Model (MLLM)
adept at concurrently processing and analyzing modalities of image, video,
audio, and text, while delivering an advanced multimodal interactive experience
and strong performance. We propose an effective multimodal training schema
starting with 7B model and proceeding through two stages of multimodal
alignment and multitask fine-tuning across audio, image, video, and text modal.
This approach equips the language model with the ability to handle visual and
audio data effectively. Demonstrating strong performance across various
omni-modal and multimodal benchmarks, we aim for this contribution to serve as
a competitive baseline for the open-source community in advancing multimodal
understanding and real-time interaction.
