About

ERNIE 5.1 is Baidu’s latest large language model designed to deliver advanced reasoning, agentic AI capabilities, creative writing, and world knowledge performance while operating with significantly improved efficiency. The model builds on the foundation of ERNIE 5.0 while reducing total parameters and training costs, allowing it to achieve flagship-level intelligence at a fraction of the computational expense of comparable models. ERNIE 5.1 performs strongly across international benchmarks for reasoning, search, knowledge, and agentic tasks, ranking among the top global AI models and leading among Chinese-developed models on multiple leaderboards. The platform introduces a new fully asynchronous reinforcement learning infrastructure that improves training efficiency, scalability, and stability for complex long-horizon AI tasks. ERNIE 5.1 also features advanced creative writing capabilities.

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.
