Baichuan-Omni-1.5 Technical Report
We introduce Baichuan-Omni-1.5, an omni-modal model that not only has
omni-modal understanding capabilities but also provides end-to-end audio
generation capabilities. To achieve fluent and high-quality interaction across
modalities without compromising the capabilities of any modality, we
prioritized optimizing three key aspects. First, we establish a comprehensive
data cleaning and synthesis pipeline for multimodal data, obtaining about 500B
high-quality data (text, audio, and vision). Second, an audio-tokenizer
(Baichuan-Audio-Tokenizer) has been designed to capture both semantic and
acoustic information from audio, enabling seamless integration and enhanced
compatibility with MLLM. Lastly, we designed a multi-stage training strategy
that progressively integrates multimodal alignment and multitask fine-tuning,
ensuring effective synergy across all modalities. Baichuan-Omni-1.5 leads
contemporary models (including GPT4o-mini and MiniCPM-o 2.6) in terms of
comprehensive omni-modal capabilities. Notably, it achieves results comparable
to leading models such as Qwen2-VL-72B across various multimodal medical
benchmarks.
Baichuan-Omni-1.5 is an omni-modal model with end-to-end audio generation, featuring a comprehensive data pipeline, audio-tokenizer, and multi-stage training strategy for superior performance across multimodal tasks.
