Ultrafast is rolling out today for GPT-6.1 Sol in the API, Codex, and ChatGPT Work. Near-Astra intelligence at up to 8x faster speeds than Sol Standard, so you can build as fast as the ideas come.

API pricing for GPT-6.1 Sol in Ultrafast mode is $12 per million input tokens and $60 per million output tokens. Built for work where speed and intelligence make a difference: debugging an outage, agents navigating apps, and live experiences where every second counts.

Is this already counting @thsottiaux s 1.5x speed up announcement or is this on top of that?

Looking forward to ultrafast being the default

stop talking nonsense you downgraded all models, GPT is stupid af I'm not a dev, but I say how to take certain actions and then SOL or Astra agrees with me and appologizes, continuously. I thought it's isolated case, but it's rule, with more people reporting same issues 👎

First you dilute the $200 plan by half, then launch features only for the $500 plan? This is Black Mirror-level shit.

They made the taxi faster and somehow the meter won.

why only Pro 500?... I get astra cause its has more usage, but 6.1 Sol?

incredible… even $200/month isn’t enough anymore

since you downgraded pro 200, you could have at least let it available for 200 pro users

When will it be available for Pro 200 users?

I don't think anyone wants this. I never wanted it. I just wanted the regular models to work reliably. They didn't. They churned all my tokens on extraneous work and rarely achieved the objectives. Idk what happened after gpt-5.5, but it was overall a turn for the worse.

Eight times faster and still no model that admits it is wrong

Already showing in ChatGPT Work for me. Standard, Fast, Ultrafast, right in the effort picker. Before you leave it on: on Pro it eats your included usage at 8x the Standard rate. Bought credits go 6x. learn.chatgpt.com/codex/agen…

still expensive, but finally makes sense to use it

ultrafast in codex is pro 500 only, and pro 200 drops from 20x to 10x plus usage after oct 29. gamers know this patch. nerf the base game, sell the speed boost

Near-Astra intelligence at 8x speed HAHA. Race is on bro, whoever ships the fast one first owns the workflow 😂

I would buy $500 if it wasn't only 25x. I have a pro sub that is yet in 20x so it would be a huge loss buying that sub.

FAR from Astra intelligence sorry. Very far - proved to be too unreliable for me i prefer Astra on High thinking gear. FAR more reliable

This is amazing you open and close your eyes and is done, then you whole monthly inference gone too!

What’s the incremental addition in cost?

This was probably the most exciting thing that was released but its just not sustainable to work with that computer from a cost perspective

Replying to @IndependentEco
Really upset about this for not being open and honest they can't offer on lower models, unless u dig deeper u can't find which model it's available. They can keep price same and stuff worst case my tokens I burnt the way I want to be . Not giving access is bad imop.
