GPT-6 Sol Pro

GPT-6 Sol in OpenAI's pro reasoning mode, built for the hardest requests you can give it.

What is GPT-6 Sol Pro?

OpenAI's pro reasoning mode is meant for difficult tasks that need more model work and can tolerate higher latency and token usage, and GPT-6 Sol Pro applies it to GPT-6 Sol.

The underlying model is the same, but each request gets more work, so answers take longer and use more tokens than on standard Sol. OpenAI hasn't published pro-mode results for GPT-6 Sol. Unlike GPT-6.1 Sol Pro, it can still run with reasoning off.

Questions about GPT-6 Sol Pro

What makes GPT-6 Sol Pro different from GPT-6 Sol?

Only the reasoning mode. GPT-6 Sol Pro is the same model with OpenAI's pro mode, so it does more work on every request.

Is GPT-6 Sol Pro slower?

Yes. OpenAI says pro mode trades higher latency and token usage for more model work on each request.

GPT-6 Sol Pro or GPT-6.1 Sol Pro?

GPT-6.1 Sol Pro is built on OpenAI's newer GPT-6.1 Sol, which makes fewer factual errors. GPT-6 Sol Pro can also run with reasoning off in Super Agent, while GPT-6.1 Sol Pro always thinks.

What reasoning effort does Super Agent use for GPT-6 Sol Pro?

It starts at low, and you can choose anything from off to max.
