About

Merrymake is a European AI think tank and dedicated research lab based in Aarhus, Denmark. We are actively working to accelerate a safe and sovereign transition to Artificial Superintelligence (ASI). Our core mission is to ensure that superhuman intelligence benefits all of life, humanity, and every individual. We believe that achieving ASI is the most profound technological leap of our time. At Merrymake, we are not just building this intelligence; we are engineering a safe bridge to get there. Rooted in European values of transparency, collaboration, and public benefit, we approach the transition with rigorous care. We actively focus on stabilizing the job market, evolving education, and partnering with governments to guarantee strict privacy and public safety. Operating at the technical frontier, our team approaches both AI capability and alignment as unified, solvable engineering challenges. Our research spans the full stack of frontier AI development.

About

SWE-1.5 is the latest agent-model release by Cognition, purpose-built for software engineering and characterized by a “frontier-size” architecture comprising hundreds of billions of parameters and optimized end-to-end (model, inference engine, and agent harness) for both speed and intelligence. It achieves near-state-of-the-art coding performance and sets a new benchmark in latency, delivering inference speeds up to 950 tokens/second, roughly six times faster than its predecessor Haiku 4.5 and thirteen times faster than Sonnet 4.5. The model was trained using extensive reinforcement learning in realistic coding-agent environments with multi-turn workflows, unit tests, quality rubrics, and browser-based agentic execution; it also benefits from tightly integrated software tooling and high-throughput hardware (including thousands of GB200 NVL72 chips and a custom hypervisor infrastructure).
