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

https://www.theinformation.com/newsletters/ai-agenda/openai-...

I wonder if AI labs are actively manipulating the narrative (and thus investor sentiment) by airing problems, and then solving them weeks to months later. I wouldn't be surprised if they have a lot of stuff figured out that is not included in the current version, just to make a steady product cycle with years of tangible improvements from one version to another (this is a common practice in the industry).

For example, if inference isn't too expensive, but they figure out how to cut costs, then price goes down. After all, why pay OpenAI when a smaller datacenter can give you similar models?

But, if they make a huge issue about how inference is too expensive, they engineer a crisis of their own creation - then, once they deploy the solution (which they might already have), then they're back on top.

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.

Pro also makes you ask it to use sub-agents instead of just doing it when useful.

Hopefully, 5.6 will automatically spawn sub-agents without needing to ask.

Will individual subscribers have access?
No Twitter, what’s he responding to?
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.

> GPT-5.5 Pro does not offer a cached input discount.

I think this tells you in one line. It's basically set up for one-shot inference right now, by the looks of things. If you use this in a harness, it would almost immediately fall apart on cost. Not to say that they couldn't make it work, just saying that at least as it's delivered currently, they haven't done so. On the web, there might be doing something to get the equivalent of that behavior internally, such as keeping the session truly alive on GPUs rather than using their external-facing cache-style approach.

Forget 5.5-pro. Why isn't everyone talking about the fact that there's no 1M context window model in codex?

Yes, I know attention degrades above ~200k, but it's still useful in many applications.

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

I wonder if clues like this will be what are written in history books as the beginning of the bubble bursting.

Everyone is insane.

Are corporate employees not allowed to use personal subscriptions?
That's kinda hilarious. Pretty soon they might just ask people to write code themselves.
interesting, our enterprise account here in Australia doesn't have access to it yet.
I'm using local models in Ollama for most things and only use the paid corporate account when my local model gets stuck.
The craziest to me was someone saying “we are using AI in daily processes, now we need to automate”.

But of course to some asshole non-technical people it meant asking for their vibe coded bullshit to be merged into production without review and fighting about it.

We are using this brand new hammer to build everything!

Please stop using this brand new hammer for glassmaking.

Dog! Use it and tell us how it is! Stop with this token maxing moaning. You have access to a new powerful tool.
wow almost as if they needed to incentivise people to use and then tame it down to keep it in sustainable levels. shocking!
Same here. It's insane that big, conservative tech companies would sign contracts saying "allow our engineers to use however much they want, we'll pay the bill later, no matter what it costs". In any other domain my company would insist on prior permission, and soft usage caps, and hard usage caps, and real-time tracking of actual dollar amounts (not just opaque tokens/credits, not just an after-the-fact view on a dashboard).

The AI companies' salespeople must be the greatest geniuses in the history of the world.

The leader boards based on token usage happened in our org for a month. Then we managed to convince the board that what matters is the reliable software shipped. Now we are back to DORA metrics.
I’ve switched to a more precise use of agents where I give less autonomy but I have much higher trust the output will be what I expect.

And I do more hand coding to guide the agent to useful patterns I want.

I feel like that’s how I used less capable agents a year ago. But I’m finding even with high quality agents, the slop creeps in.

I want more control. I want to save money. Hence going back to a more 80/20 agent to human LoC split.

GPT 5.5's double token cost was the threshold for me. These things are getting expensive quickly - the subsidized pricing can't go on forever.

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.

All these names mean squat
Will it have similar limited access like Fable? It is an interesting timeline, as general access for Fable (without using extra credits) is coming to an end :(
It is like with drug dealers, you get some free dose, then cheap one, then you pay an arm and a leg.

Somebody has to finaly pay for these heaps of accelerator hardware.

they better get that out fast, it will become totally meaningless when the next GLM gets there first.

more competition is always good for consumers.

Hope this forces Anthropic to be less stingy with Fable.
Not including their best model in a max subscription would otherwise be truly a good reason for once to consider going back to openai for me. I'll at least try it.
It is not because they want to but because they literally don't have the capacity to.
Hopefully they aren't, and their business dies. They're not a good company.
Yeah. I'll switch to OpenAI if they release Sol on their subscription tiers.
I’m all in on Anthropic. How good is frontier openAI models for coding and things?
Bruh when did understanding chatbots become like following pokemon? Wtf does any of this this mean. Tf is sol? Tf is ultra? Tf is codex? Tf happened to descriptive nomenclature?
And this is a level beyond Sol, I call it Super Sol 2.
Nice! It never made sense to me that Pro Extended wasn't in the Codex app.
I can see they have inherited their poor product naming from Microslop
Has anyone already tried 5.6 Sol in their day to day coding/development activities?

How does it compare to GPT-5.5?
