Poolside releases Laguna S 2.1, the West’s most capable open-weight model

Poolside released Laguna S 2.1, a 118-billion-parameter open-weight model for agentic coding that matches larger models on benchmarks while being small enough to run on a single desktop. The model is available under an OpenMDW-1.1 license and addresses the gap in Western open-weight AI options as enterprises shift toward cost-efficient, self-hosted solutions.
