WorldofAI · youtube · 2026-07-23

Poolside AI’s Laguna S 2.1 is presented as a new open-weight model with 118B total parameters, 8B active parameters, a 1M-token context window, and both thinking and non-thinking modes.

The video tests it on coding and local-run scenarios, including benchmarks against GLM 5.2, Qwen 3.7 Max, Hy3, and Kimi K3. The creator claims the model was trained from scratch and released in under 9 weeks, and says it may be one of the strongest local coding models available today.
