Benchmarks
These two models do not currently report scores on any of the same benchmark suites, so there is no like-for-like capability comparison to show. Rather than pad the page with one-sided numbers, the benchmark leaderboards list every score we do hold.
What each model is for
GPT-5.6 Sol
OpenAI · Frontier
The flagship tier of the GPT-5.6 family, aimed at complex reasoning, long-horizon agentic work, coding, biology and cybersecurity. In OpenAI's naming the number is the generation and Sol is a durable capability tier, so Sol advances on its own cadence rather than being replaced by the next decimal. Standard short-context pricing is $5/$30 per MTok with cached input at $0.50; requests above 272K tokens are billed at the long-context rate of $10/$45.
