SWE‑2 reshapes BuildingBench’s cost–quality frontier 👀🏗️ @cognition's SWE‑2 (max) scores 67.3—just 2.5 points behind GPT‑6 Sol (ultra, 69.8), and ahead of GPT‑5.6 Luna (61.6). Free to use for now, it reshapes the budget end of the cost–quality curve: building in 3D just got more accessible. It's really a good model. Congrats @cognition @ScottWu46 @jaredpalmer ! How much can you build on a $0 model budget? 🚀
