Summary

What changed
Vercel added Poolside's Laguna S 2.1, an open-weight Mixture-of-Experts model for agentic coding and long-horizon tasks, to AI Gateway in free and paid versions.
Why it matters
Adding an open-weight, coding-specialized MoE model to a widely used gateway lowers the barrier to trying non-frontier coding models and strengthens Poolside's distribution against closed incumbents, while reinforcing AI Gateway's role as a neutral aggregation point across open and proprietary models.
