About
Laguna XS.2 is Poolside’s open-weight agentic coding model, built as the lightest and fastest model in the Laguna family. It is a 33B total-parameter Mixture of Experts model with 3B activated parameters, trained completely in-house on 30T tokens. As Poolside’s newest generation model open to the community, Laguna XS.2 is a second-generation architecture and the company’s first open-weight model, built on the lessons learned from training Laguna M.1 across synthetic data and reinforcement learning. The model is designed for agentic coding workflows, where it can code, act, iterate quickly, and perform best inside Poolside’s coding agent. Laguna XS.2 is positioned as a strong model for rapid agentic iteration, especially for developers and teams that need a compact, efficient coding model rather than a heavier frontier system. It is released under an Apache 2.0 license, allowing the community to evaluate, fine-tune, quantize, serve, and build on the weights.

About
Polyant is an open source platform for building teams of specialised AI agents that work alongside the people in a company, handling work like sales briefs, customer triage, document extraction, and compliance reporting.
Its composable, self-hosted architecture lets teams choose their own model providers, including open-weight models, and their own infrastructure, so they're never locked into one vendor. Governance and audit tooling designed around EU AI Act requirements is built in from day one, with every agent decision logged in an audit registry compliance teams can query directly. Companies keep full control over data residency, deploying on-premises, in their own cloud, or on EU infrastructure managed by Exelab. And agents reach production in days rather than months, without giving up self-hosting or governance.
It's built for mid-to-large European enterprises in regulated sectors like banking, insurance, and healthcare, where "just use a hosted API" isn't an option.
