About

ERNIE X1.1 is Baidu’s upgraded reasoning model that delivers major improvements over its predecessor. It achieves 34.8% higher factual accuracy, 12.5% better instruction following, and 9.6% stronger agentic capabilities compared to ERNIE X1. In benchmark testing, it surpasses DeepSeek R1-0528 and performs on par with GPT-5 and Gemini 2.5 Pro. Built on the foundation of ERNIE 4.5, it has been enhanced with extensive mid-training and post-training, including reinforcement learning. The model is available through ERNIE Bot, the Wenxiaoyan app, and Baidu’s Qianfan MaaS platform via API. These upgrades are designed to reduce hallucinations, improve reliability, and strengthen real-world AI task performance.

About

Patronus AI provides frontier AI labs with training data, tasks, and simulated environments for reinforcement learning. The company builds RL environments that replicate real-world digital workflows across software engineering, computer use, customer support, and financial services. Each environment pairs simulated applications with tasks and reward signals, so models can practice long-horizon, multi-step work under realistic conditions such as latency, interface changes, and unexpected pop-ups. Patronus AI also develops Digital World Models, AI models trained to predict how digital environments behave, which are used to generate and evolve training environments at scale as models improve. Its work spans reinforcement learning environments and digital world models for agents operating in software, supporting post-training, benchmarking, and evaluation of frontier AI models and agents.
