  • BEIJING, March 16, 2025 /PRNewswire/ -- Baidu, Inc. (NASDAQ: BIDU and HKEX: 9888), a leading AI company with strong Internet foundation, today launched its latest foundation models, including native multimodal foundation model ERNIE 4.5 and deep-thinking reasoning model ERNIE X1. Both models are now freely accessible to individual users through ERNIE Bot's official website (https://yiyan.baidu.com/).

    The launch of ERNIE 4.5 and ERNIE X1 marks a significant milestone in pushing the boundaries of multimodal and reasoning models, offering advanced capabilities at a more accessible price point. It also underscores Baidu's commitment to continued investment in developing smarter and more powerful next-generation foundation models.

    Baidu also plans to progressively integrate both ERNIE 4.5 and X1 into its product ecosystem. This integration will include Baidu Search, the Wenxiaoyan app, and other offerings, delivering a more versatile and enhanced experience to a broader base of individual users.

    With the addition of ERNIE 4.5 and ERNIE X1 today, ERNIE Bot is being made free to the public ahead of schedule. Earlier this year, the company announced a plan that ERNIE Bot would become fully-free to individual users starting April 1. For enterprise users and developers, ERNIE 4.5 is now accessible via APIs on Baidu AI Cloud's MaaS platform Qianfan, while ERNIE X1 is set to be available on the platform soon.

    ERNIE 4.5: Baidu's New Generation Native Multimodal Foundation Model

    ERNIE 4.5 is Baidu's new generation native multimodal foundation model independently developed by the company. It achieves collaborative optimization through joint modeling of multiple modalities, demonstrating exceptional multimodal comprehension capabilities. With refined language skills, it exhibits comprehensive improvements in understanding, generation, reasoning and memory, along with notable enhancements in hallucination prevention, logical reasoning, and coding abilities.

    ERNIE 4.5's multimodal capabilities are evident in its ability to integrate and understand text, images, audio, and video content.

    ERNIE 4.5 also possesses strong intelligence and contextual awareness, effortlessly understanding internet memes, satirical cartoons, and more.

    As Baidu's latest foundation model and native multimodal model, ERNIE 4.5 outperforms GPT-4.5 in multiple benchmarks while priced at just 1% of GPT-4.5.


    The significant enhancements in ERNIE 4.5's capabilities are attributed to several key technologies including "FlashMask" Dynamic Attention Masking, Heterogeneous Multimodal Mixture-of-Experts, Spatiotemporal Representation Compression, Knowledge-Centric Training Data Construction, Self-feedback Enhanced Post-Training.

    ERNIE X1: Baidu's New Deep-Thinking Reasoning Model

    ERNIE X1 possesses enhanced capabilities in understanding, planning, reflection, and evolution. As Baidu's first multimodal deep-thinking reasoning model capable of tool use, X1 also excels in Chinese knowledge Q&A, literary creation, manuscript writing, dialogue, logical reasoning, and complex calculations.

    Specifically for tool use, X1 supports various tools including advanced search, Q&A on given document, image understanding, AI image generation, code interpreting, webpage reading, TreeMind mapping, Baidu academic search, business information search, and franchise information search.

    The comprehensive uplift in ERNIE X1's capabilities is underpinned by key technologies such as the Progressive Reinforcement Learning Method, End-to-End Training Approach Integrating Chains of Thought and Action, and A Unified Multi-Faceted Reward System.

    Enterprise users and developers can directly access ERNIE 4.5's API through Baidu AI Cloud's Qianfan Foundation Model Platform, with input prices starting as low as RMB 0.004 per thousand tokens and output prices at RMB 0.016 per thousand tokens.  ERNIE X1 will soon be available on the Qianfan Platform, with input prices as low as RMB 0.002 per thousand tokens and output prices as low as RMB 0.008 per thousand tokens.

    2025 is set to be an important year for the development and iteration of large language models and technologies. With the launch of ERNIE 4.5 and ERNIE X1, Baidu will continue to invest in artificial intelligence, data centers and cloud infrastructure to advance our AI capabilities, and develop smarter and more powerful next-generation models.
