Wenxin Large Model 4.5 - Baidu's first native multimodal large model

What is Wenxin's large model 4.5?

Wenxin Big Model 4.5 is Baidu's latest generation and first native multimodal big model, officially released. It has significant improvements in multimodal understanding, text and logical reasoning, and outperforms GPT4.5 in multiple tests. The model is now available on Baidu AI Cloud Qianfan Big Model Platform, and enterprise users and developers can log in to access its API.

The main functions of Wenxin Large Model 4.5

• Comprehensive understanding of multiple modalitiesIt can comprehensively understand multiple modalities such as text, images, audio, and video, and achieve multimodal collaborative optimization. For example, it can understand complex content such as charts, memes, and satirical cartoons, and perform accurate analysis and interpretation.
• Enhance multimodal fusion capabilitiesBy using multimodal heterogeneous expert extension technology, the problem of uneven gradients between different modes can be solved, thereby improving the multimodal fusion capability.
• understanding abilityIt has a more accurate understanding of language and can handle complex language logic and semantics.
• Generation capabilityThe generated text is more natural and fluent, with higher accuracy and creativity.
• Logical reasoningIt significantly improves logical reasoning ability and enables better handling of complex logical problems.
• Coding abilityIt supports code generation and interpretation, making it suitable for scenarios such as programming assistance.
• Knowledge accuracyBy using large-scale data construction technology based on knowledge points, we can significantly reduce model illusions and improve knowledge accuracy.
• High emotional intelligence and cultural understandingThey can understand internet memes and cultural allusions, demonstrating "high emotional intelligence," and can explain them in the context of cultural background.

Technical Principles of Wenxin Large Model 4.5

• Multimodal fusion technologyWenxin Big Model 4.5 achieves collaborative optimization through multi-modal joint modeling, enabling comprehensive understanding of various content such as text, images, audio, and video.
• FlashMask Dynamic Attention MaskThe model's attention mechanism has been optimized, making it more efficient when handling long texts and multi-turn interactions.
• Multimodal heterogeneous expert extension technologyBy combining the adaptive modality-aware loss function, the problem of uneven gradients between different modalities is solved, and the multimodal fusion capability is improved.
• Spatiotemporal dimension representation compression technologyEfficient compression of semantic representations of images and videos in the spatiotemporal dimension improves the model's efficiency in processing spatiotemporal information.
• Large-scale data construction technology based on knowledge pointsBased on knowledge hierarchical sampling, data compression and fusion, and targeted synthesis of scarce knowledge points, high-knowledge-density pre-training data is constructed to improve model learning efficiency and reduce model illusion.
• Post-training techniques based on self-feedbackA self-feedback iterative post-training technique that integrates multiple evaluation methods improves the stability and robustness of reinforcement learning.
