Ultrafast is available today for GPT-6 Astra in Codex, ChatGPT Work, and the API, with GPT-6.1 Sol coming soon. To access it in Codex and ChatGPT Work, we’re introducing Pro 500—a new plan with our highest usage limits (25x Plus) and access to Ultrafast. chatgpt.com/pricing

We’re also reopening Pro 200 subscriptions, with continued access to frontier models like Astra, including our new GPT-6.1 Sol model which brings near-Astra capabilities to a model you can use every day. Our commitment is that your subscription will continue to help you get more work done with an increasing level of quality. We are also committing to not reintroducing the 5hr limit so that you can fully use your weekly usage when you want.

So To get ultrafast you need to buy the $500 plan which only gets you 25% more usage than the $200 plan? You can get double the usage by just buying 2 20x plans and 1 10x plan…. For the same price. Yet, you’re still paying 8x usage for ultrafast with the $500 sub? Hello????

Eight times faster and I still do not know if it is telling the truth. Speed was not the part that scared me.

Thanks for completely destroying my trust in your company. Cancelling my Codex 200x and sticking with my 200x Anthropic plan!

Hopefully you realize that withdrawing codex spark from the 200 plans, then gate keeping it to the 500$ one, is the most disgusting practice possible I subbed to the pro tier, to use the Pro effort (that wasn't clearly written that it wasn't available in the CLI, which was already so poorly written that I thought it was a misconfig on my end. Trace back to the mail you sent to people when codex 5x (100$) released, see the mail offer you sent to subscribers. And check the webpage referencing the codex pro. I read it all, after doing so, I said, well yeah I'll sub to this. Also, will be trying this codex spark thing. After doing so, realized codex spark was literally the whole selling point of the pro sub and had great usage. Now, it has neither. So, good luck, guys. Showing in such a small time frame that servicing gets worse, access gets worse, capabilities worsen, even the model upgrades are actually worsening.
