Poolside open-sources Laguna S 2.1, a 118B agentic coding model with a 1M-token context window

Poolside released Laguna S 2.1, an open-weight 118B-parameter MoE (8B active) built for agentic coding, following the smaller Laguna XS 2.1 (33B/3B) from earlier in July. It runs up to a 1M-token context and scores 70.2 pass@1 on Terminal-Bench 2.1 — matching or beating open models several times its size, including DeepSeek-V4-Flash and Nemotron 3 Ultra, on agentic coding benchmarks. Both Laguna models are free for a limited time on Hugging Face under the permissive OpenMDW license.
