Open weight models galore! Laguna S 2.1 went from the start of training to launch in under 9 weeks! Custom & open models are putting a lot of pressure on the frontier closed and general models. No wonder they want to ban them. Diverse intelligence is good for the market. https://t.co/WkY8ONkQpa ![photo](https://pbs.twimg.com/media/HNyVaxRXIAAi6Eb.jpg) > **引用原帖 Poolside (@poolsideai):** > Today we're releasing Laguna S 2.1, our most capable model to date. > It's a 118B total parameter Mixture-of-Experts model with 8B activated per token, a context window of up to 1M tokens, and thinking and no-thinking modes. > Capable enough to hold its own against models many times its size. Small enough to run on a single @NVIDIAAI DGX Spark. > Laguna S 2.1 is fully open under OpenMDW-1.1, with weights available today on @huggingface > https://t.co/xxGeAgo35R > https://x.com/poolsideai/status/2079613777343848465
