What is SWE-1.5?

Cognition has introduced SWE-1.5, the latest agent-model tailored for software engineering, which boasts an extensive "frontier-size" architecture comprising hundreds of billions of parameters alongside a comprehensive end-to-end optimization that enhances both its speed and intelligence. This advanced model nearly reaches state-of-the-art coding capabilities and sets a new benchmark for latency, achieving inference speeds of up to 950 tokens per second, which is nearly six times the speed of its forerunner, Haiku 4.5, and thirteen times faster than Sonnet 4.5. Developed through rigorous reinforcement learning in realistic coding-agent environments that entail multi-turn workflows, unit tests, and quality evaluations, SWE-1.5 utilizes integrated software tools and high-performance hardware, including thousands of GB200 NVL72 chips coupled with a bespoke hypervisor infrastructure. Its innovative design facilitates more efficient management of intricate coding challenges and significantly boosts productivity for software development teams. With its combination of rapid performance, efficiency, and smart engineering, SWE-1.5 is set to revolutionize the coding model landscape and help developers tackle their tasks more effectively. The potential impact of this model on the future of software engineering practices cannot be overstated.

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.
