According to a recent LinkedIn post from OpenRouter, the company is now hosting Poolside AI’s Laguna M.1 and Laguna XS.2 foundation models on its platform. The post describes these models as designed for agentic coding and long-horizon tasks, and indicates they are available free for a limited time.

The LinkedIn post highlights Laguna M.1 as a 225B-parameter mixture-of-experts model with 23B active parameters, positioned as Poolside AI’s most capable offering. It also describes Laguna XS.2 as a 33B-parameter MoE model with 3B active parameters, characterized as competitive among open-weight models from Western labs in its size class.
For investors, the post suggests OpenRouter is expanding its catalog with high-end, developer-focused AI models, potentially strengthening its value proposition as a distribution layer for advanced LLMs. Making these models freely accessible for a limited period may help drive developer adoption, increase platform usage, and deepen relationships with emerging AI model providers.
This move could enhance OpenRouter’s positioning within the AI infrastructure ecosystem, particularly in the niche of tools for software agents and coding automation. If the models gain traction, OpenRouter may benefit from increased traffic, potential monetization opportunities once free access ends, and a stronger role as an intermediary between AI labs and downstream enterprise users.
