GPT-6.1 Sol Pro
GPT-6.1 Sol in OpenAI's pro reasoning mode, for hard problems where accuracy beats speed.
What is GPT-6.1 Sol Pro?
GPT-6.1 Sol Pro is GPT-6.1 Sol with OpenAI's pro reasoning mode switched on.
OpenAI documents pro as a setting on the same model ID, meant for difficult tasks that need more model work and can tolerate higher latency and token usage. Answers take longer and use more tokens than the same request on standard GPT-6.1 Sol. OpenAI hasn't published benchmark results for pro mode, so the official results on the GPT-6.1 Sol page are the closest reference.

How GPT-6.1 Sol Pro performs
On LMArena
People compare two anonymous answers and vote for the better one. Ranked here against the other chat models you can pick in Super Agent.
LMArena has no separate entry for GPT-6.1 Sol Pro. It runs the same model as GPT-6.1 Sol in a deeper reasoning mode, and that page shows the base model's arena results.

What you can do with GPT-6.1 Sol Pro
Same model as GPT-6.1 Sol, run in OpenAI's pro reasoning mode
More model work on every request, at every effort level
Keeps GPT-6.1 Sol's 1.05M-token context and image input
Effort from low to max, as on the base model
How to prompt GPT-6.1 Sol Pro
- Ask for one well-defined result per message. Pro mode works best on a single hard problem.
- Give it every constraint and reference at once, since each round trip takes a while.
- Try the question on GPT-6.1 Sol first and switch to Pro only if the answer falls short.
Where GPT-6.1 Sol Pro fits best
One hard question where a wrong answer is costly
Planning a complex multi-asset campaign before generating anything
Checking a long script or brief for logic gaps
Problems GPT-6.1 Sol got wrong on the first try

Good to know before you start
- Slower than GPT-6.1 Sol on the same request
- Uses more tokens per answer, which OpenAI notes also raises cost
- OpenAI publishes no pro-mode benchmarks, so the gain is hard to measure up front

Questions about GPT-6.1 Sol Pro
Is GPT-6.1 Sol Pro a different model from GPT-6.1 Sol?
No. OpenAI serves the same model with its reasoning mode set to pro, which makes it work longer before answering.
When should I use GPT-6.1 Sol Pro?
For difficult questions where you can wait longer for the answer. OpenAI keeps standard mode as the default and offers pro for tasks that need more model work.
Why is GPT-6.1 Sol Pro slower?
Pro mode does more work per request, so it uses more tokens and takes longer than the same request on GPT-6.1 Sol.
Are there official benchmarks for GPT-6.1 Sol Pro?
No. OpenAI hasn't published results for pro mode. Its launch results cover GPT-6.1 Sol across its standard effort levels, and you can find them on the GPT-6.1 Sol page.
Which reasoning levels does GPT-6.1 Sol Pro support in Super Agent?
Low, medium, high, extra high and max. Thinking is always on, and Super Agent starts it at low.
