What is Patronus AI?

Patronus AI is a research lab focused on the data and simulations that frontier AI models learn from. Its main offering is a catalog of reinforcement learning environments covering software engineering, computer use, customer service, and finance, each built to reflect how real applications behave rather than idealized versions of them. Agents receive tasks inside these simulated applications and are scored with reward signals, giving AI labs a way to improve performance on long, multi-step workflows. The company is also developing Digital World Models, which predict the behavior of digital environments and allow training environments to be generated at scale instead of being built one at a time by hand. These environments and models support the post-training and evaluation of AI agents that operate in software.

What is LongCat-2.0?

LongCat-2.0 signifies a remarkable leap forward in the field of language models, boasting an impressive 1.6 trillion parameters through a Mixture-of-Experts architecture that utilizes AI ASIC superpods, with around 48 billion parameters activated per token, demonstrating outstanding proficiency in coding and agentic functions. This model notably surpasses its predecessors by incorporating a large-scale sparse architecture along with specialized post-training techniques designed specifically for applications in real-world software development, tool usage, long-context reasoning, and intricate agent operations. Entirely built and executed on AI ASIC superpods, LongCat-2.0's pretraining involved processing over 35 trillion tokens and countless accelerator hours, highlighting the forefront of training techniques on state-of-the-art hardware. To further enhance its capabilities on tasks that require long-term contextual awareness, the model integrates LongCat Sparse Attention and is trained with hundreds of billions of tokens derived from 1M-context datasets, which empowers it to adeptly handle ultra-long context challenges and maintain a comprehensive understanding of extensive documents. This unique blend of features not only establishes LongCat-2.0 as an innovative leader in advanced language models but also sets a new benchmark for future developments in the domain. Its capabilities are likely to inspire a new wave of research and applications in the field.
