XploreAi released RWE-Bench results: Fable 5.2 tops the leaderboard at 62%, more than double Opus 5.5, and is better across every tested domain — mechanical, design for manufacturing, CFD and electronics.
Carbon scores 20%, just behind Opus 5.5 and Sol, beating Argon on mechanical design and slightly ahead on electronics. Terra gets 19%, below Sol at a higher average cost per task, falling behind on longer electronics and CFD tasks. Nemotron starts at 0%, joining Grok, Muse and other open-source models. Jsevillamol notes Fable 5.2 is very good at engineering.
