New: read our technical report on Laguna M.1 and Laguna XS.2.
Our most recent release: Laguna S 2.1 (118B-A8B), designed for agentic coding and long-horizon work. Laguna S 2.1 outperforms larger coding agent models, scoring 40.4% on DeepSWE. Free to use under OpenMDW-1.1.
Our efficient small model: Laguna XS 2.1 (33B-A3B), designed for agentic coding and long-horizon work on a local machine. It uses Sliding Window Attention with per-head gating in 30 out of 40 layers for fast inference and low KV cache requirements.
Our first flagship model, now available open weight: Laguna M.1 (225B-A23B) is available in base and post-trained (BF16, FP8 and NVFP4) variants under Apache 2.0 licenses. 49.2% on SWE-Bench Pro.
