Model Card
Laguna XS.2 is Poolside's compact, open-weight agentic coding model — a 33B-parameter Mixture-of-Experts architecture with only 3B activated parameters, released under the Apache 2.0 license.
Despite its small footprint, it performs remarkably close to its larger sibling: 68.2% on SWE-bench Verified and 44.5% on SWE-bench Pro, nearly matching models many times its size. It supports the same agentic coding workflows as Laguna M.1, including tool use and multi-step reasoning.
XS.2 is a second-generation model that incorporates lessons from M.1's training pipeline. It's a strong fit for developers who want a capable coding agent with low inference cost, or who need the flexibility of open weights for custom deployments.
