GPT-5.6 Sol Ultra will be in Codex

For context:

> Additionally, we’re introducing a new ultra mode that goes beyond the capabilities of a single agent by leveraging subagents to accelerate complex work.

Can someone explain how this compares with Pro? I thought Pro was already something similar.

I wonder if it's related that that OpenAI has found a way to cut inference costs by half, according to The Information.

I'm working in large US corporation. And I see that I already have access to 5.6-Sol Ultra on my corporate account.

I haven't really used it yet.

2 months ago management was showing us scoreboards, praising leaders who used most tokens. Last few weeks, we're getting weekly emails, telling us that whenever we can - we should use cheaper models, and that we should watch the page which shows our tokens usage.

Recently, I've been so eager to get new model releases in Codex. I'm hooked. I hope this accelerates development. Shows how dependant I have become to Codex.

when will it be available? do we know? I don't have X, not sure if the thread mentions it.

Will individual subscribers have access?

I still don't know why OpenAI doesn't put gpt-5.5-pro in Codex. It's one hell of a model and easily parallels Fable/Mythos. Sure, it'll use up your quota much faster but that's the price some users are willing to pay for absolutely high quality responses.

I think gpt-5.5-pro runs 12x parallel gpt-5.5 agents behind the scene and uses OpenAI's secret sauce to synthesize their answers into one insanely good response.

Gamechanger..
