According to cited sources, GPT-5.6 Sol took 1st place in official Design Arena results with an Elo of 1353.
It outperformed Claude Fable 5 and ranks alongside GLM 5.2 in front-end design performance. Compared to GPT-5.5, it jumped 18 places and gained 60 Elo points. The source notes this is driven by improved post-training on the same base model rather than new pre-training; future pre-training in GPT-6 could push performance even further.
