Poolside, a San Francisco AI lab, released Laguna S 2.1 on Tuesday—a 118-billion-parameter Mixture-of-Experts coding model that activates only 8 billion parameters per token and supports a context window of up to 1 million tokens. The model scores 70.2% on Terminal-Bench 2.1, placing it 11th on Poolside's leaderboard. Weights are available immediately on Hugging Face under the permissive OpenMDW-1.1 license.
