LiveBench leaderboard: cost-performance divergence at the top
The LiveBench top four are separated by 2.2 points. The cost difference is brutal.
GPT-5.6 Sol takes the overall crown on LiveBench with an 82.4 average, but Claude Fable 5 trails by just 1.6 points at nearly three times the cost. The real story is how the pack below has thinned out, and where the dollar smarts stop.

Benchmark integrity
GPT-5.6 Sol almost cracked a physics benchmark built so AI couldn't cheat
GPT-5.6 Sol (max) leads CritPt, a new physics benchmark built from unpublished graduate-level research problems, scoring roughly 5 points above GPT-5.5 and 4 points ahead of Claude Fable 5, but even the winner solved only a third of the problems.

Benchmark deep dive
GPT-5.6 just made every dollar in AI count harder
OpenAI's GPT-5.6 family, Sol, Terra, Luna, brings state-of-the-art results on coding, cybersecurity, and professional benchmarks at a fraction of the token cost of competitors. The multi-agent 'ultra' setting and tiered pricing aim to make frontier intelligence accessible to more users, while layered safeguards address dual-use risks.
