Baidu Unveils Reasoning Model ERNIE X1.1 with Upgrades in Key Capabilities

Core Insights - Baidu has unveiled significant advancements in AI technology at the WAVE SUMMIT 2025, including the ERNIE X 1.1 reasoning model, an upgraded PaddlePaddle framework, and the AI coding assistant Baidu Comate 3.5S, along with the open-sourcing of the ERNIE-4.5-21B-A3B-Thinking model [1][8]. ERNIE X 1.1 Model - The ERNIE X 1.1 reasoning model shows major improvements in factuality (up 34.8%), instruction following (up 12.5%), and agentic capabilities (up 9.6%) compared to its predecessor ERNIE X [2]. - ERNIE X 1.1 outperforms DeepSeek R1-0528 and matches the performance of leading models like GPT-5 and Gemini 2.5 Pro [2][8]. - The model is accessible via the ERNIE Bot website and the Wenxiaoyan app, and is deployed on Baidu AI Cloud's Models-as-a-Service platform [3]. PaddlePaddle Framework - The PaddlePaddle framework version 3.2 introduces enhancements in model training, hardware compatibility, and ecosystem support, addressing challenges in model training with computational optimization, parallel strategies, and native fault tolerance [4]. - The framework achieves a pre-training MFU of 47% on the ERNIE-4.5-300B-A47B model, significantly boosting efficiency [4]. Baidu Comate 3.5S - Baidu Comate 3.5S enhances multi-agent collaboration, allowing a single developer to achieve the productivity of an entire team [6]. - The upgrade includes stronger business understanding, improved task execution accuracy, and a unified knowledge base for seamless knowledge transfer within teams [7]. Open-Sourcing of ERNIE-4.5-21B-A3B-Thinking Model - The ERNIE-4.5-21B-A3B-Thinking model supports a 128K context window and excels in complex reasoning tasks, including content creation and code generation [9]. - This lightweight model has 21 billion total parameters, with 3 billion active parameters, achieving near-state-of-the-art performance at a reduced scale [10]. - The model is available on platforms like Hugging Face and Baidu AI Studio, following the open-sourcing of 10 other ERNIE 4.5 models [10]. Ecosystem Impact - The PaddlePaddle-ERNIE ecosystem has served 23.33 million developers and 760,000 enterprises, while Baidu Comate has supported over 10 million developers [5][8]. - Within Baidu, 45% of new code is now generated by AI, indicating a significant shift towards AI-driven development [9].
