What Baidu, Inc. does.

We are a leading AI company with a strong internet foundation. We have been consistently investing in AI since 2010 to advance our technological capabilities, enhance our search functionality and boost overall monetization. The breadth and depth of our AI capabilities provide the differentiating foundational technologies that power all of our businesses.

We are in the midst of a broad-based platform shift driven by generative AI and foundation models that is set to revolutionize every industry. To capture this opportunity, we launched ERNIE Bot, our conversational AI bot powered by ERNIE, our in-house foundation model, in the first quarter of 2023. We have continued to expand the ERNIE family of models. In May 2023, we launched ERNIE 3.5, which served as the latest foundation model powering ERNIE Bot at that time. According to the International Data Corporation (IDC)’s latest report on the technological abilities of AI models, issued in July 2023, ERNIE 3.5 excelled in many areas, such as algorithm, industry coverage, developer tools and ecosystem. In October 2023, we launched ERNIE 4.0 (EB4), our most advanced foundation model at the time. EB4 is a GPT4-type of model, displaying human-level performance in understanding, content generation, complex reasoning and memory retention. These capabilities are crucial for developing AI-native applications and solutions. In June 2024, we launched ERNIE 4.0 Turbo, which provides superior capabilities for typical use cases and is designed to run faster and at lower cost compared to ERNIE 4.0. We have been using the ERNIE family of models to renovate our products and offerings in order to provide AI-native experiences. In 2025, we accelerated the pace of model iteration to meet the rapidly expanding adoption of AI across a broad range of application scenarios. In March 2025, we released ERNIE 4.5, our first flagship foundation model with multimodal capabilities, and ERNIE X1, our first reasoning model with best-in-class function calling, tackling complex problems with extended chains of thought. In April 2025, we further unveiled enhanced versions, ERNIE 4.5 Turbo and ERNIE X1 Turbo, delivering improved performance at significantly lower pricing. In November 2025, we unveiled ERNIE 5.0, our first native omni-modal foundation model. ERNIE 5.0 delivers strong performance across omni-modal understanding, creative writing, and instruction following. In January 2026, we released an updated version of ERNIE 5.0.
