- Laguna XS.2 is open-source, Apache 2.0 licensed, and affordable.
- Models are optimized for agentic workflows and coding tasks.

San Francisco-based AI startup Poolside has introduced two new large language models, Laguna M.1 and Laguna XS.2. The Laguna XS.2, an open-source model licensed under Apache 2.0, is designed for efficiency and community innovation, allowing developers to run it locally on a single GPU.
The flagship Laguna M.1 is optimized for complex enterprise and government needs, focusing on high-consequence software engineering problems. Both models were trained from scratch and are optimized for agentic workflows, enabling AI to take autonomous actions and write code.
Benchmarks indicate that the Laguna models perform competitively, with XS.2 showing remarkable efficiency for its size. Poolside also released "pool," a terminal-based coding agent, and "shimmer," a mobile-optimized web development environment, enhancing the utility of their new AI offerings.
Poolside's release of Laguna XS.2 as open weights signals a commitment to fostering the open-AI ecosystem. The company believes this approach is the fastest path to improving their work through community evaluation and fine-tuning, aiming for "abundance for humanity."
