On 29 September OpenAI announced more than twenty things at DevDay in San Francisco: dots, always-on agents with a computer of their own; GPT-6.1 Sol, which OpenAI says comes close to Astra at a fifth of the price; ChatGPT Space and Pages for teams working alongside agents; Codex in the cloud, computer use in the Agents API, and a Pro 500 plan. We are collecting the launches in OpenAI's own words, what was shown on stage, what people tried and argued about in the first hours, and the night before, each in the poster's own words. Nobody in these bylines is on eChai, and every entry links back to where it was posted.

TestingCatalog on the new top tier as it was announced. OpenAI's recap describes Pro 500 as 25 times the Plus allowance, with Ultrafast included.

BREAKING 🔥: OpenAI announced ChatGPT Pro 500 plan, with x25 usage capacity and access to Ultrafast mode.
No 5h limit, too 👀
Lisan al Gaib, who runs the LisanBench benchmark, laying the four plans side by side once Pro 500 was announced. The old 20x is what the $200 plan carried until the change the night before.

OpenAI is doing the Anthropic thing with their subscriptions
misleading naming.
so you are now basically paying $500 for the old 20x subscription lmao
Plus = 1x
Pro 100 = 5x
Pro 200 = 10x
Pro 500 = 25x
Tibo's second go, two hours before the keynote: Plus as one unit of usage, Pro 100 as five and Pro 200 as ten, with existing subscribers keeping twenty for a while plus extra credits.

I’ll explain the new Pro 200 plan differently, before I start live tweeting from DevDay on things that are going out!
Today we are going to ship a number of things that increase what you can do across the Plus and Pro plans. A lot of compute is online for this increase. As we increase the floor, we are changing the relative difference between plans to be
Plus = 1X
Pro 100 = 5X
Pro 200 = 10X
and we are reopening subscriptions for Pro 200 (we had paused it). If you have an existing plan you will keep the 20X multiplier for a bit and also receive a lot of additional credits because we know changes are hard even if it means that everyone will get more in the end.
Five lines that went round the morning of the keynote. The first is GPT-6.1 Astra, which OpenAI said the day before it would not release because it did not meet its safety standards.

- Delayed release of Astra 6.1
- 20x plan is now 10x plan
- 5x plan is now 2.5x
- You will pay $500 now to get the same limits as you did on the $200 plan
- GPT 6 Sol is a disappointment
OpenAI has completely lost it. Not even excited for DevDay anymore.

Same model price + half the budget → roughly half the usage, given comparable tasks and settings.
So: $200 plan is now $100 plan, $20 is now $10. What the frick.
Announcing this cut right before DevDay is the most absurd timing imaginable.
It will cast a negative shadow over DevDay and reflect poorly on the event. I understand that OpenAI is facing compute issues - to the point where they even had to pause new subscriptions - but this cut is going to backfire.
Tibor Blaho, who builds AIPRM for ChatGPT and Claude, on the same change, with the other side of it: that the plan had been too good to last.

This is sad and very bad news (especially for Astra users), right ahead of the exciting DevDay today, but I guess there is never a good time for bad news & for things that need to be done
It has been clear for a while that the Pro 20x plan was too good to be true and would not last long
Sam said back in January 2025 that they were losing money on Pro, and that was the o1 era, before having Codex running all day
Tibo, who works on Codex and ChatGPT at OpenAI, the night before DevDay. The $200 Pro plan reopened to new subscribers with its usage counted a new way, which by Tibo's own arithmetic nets out at half the dollar value in API spend of the old plan. It was seen more than twelve million times, and it set the mood of the morning before the keynote.

Hi,
Tomorrow we are re-opening the Pro $200 subscriptions to new subscribers, but together with it we are also changing how we calculate the usage for it. In effect, if you do the math, it will net out at half the dollar in API spend compared to the old Pro $200 plan.
Now that it's said, let me explain why this is happening and why you will still get more work done than if you were on the Pro $200 subscription one month ago.
(a) We didn't want to compromise in other ways and are committing to not reintroducing the 5h limit, so that you can fully use the weekly usage when you want.
(b) On the subscription, we guarantee that over time you always get more work done and with an increasing level of quality. This means that you will continue to get more value per dollar spent as a result of models getting more efficient and us passing down the improvements in the form of API price reductions.
(c) We don't want to put an incentive on ourselves to artificially inflate the API list prices to make it look like you are getting a lot (and workaround it through discounts, etc). Instead we want to continue to both rapidly reduce prices and increase capabilities of models on the API. This week we introduced GPT-6 Sol and GPT-6 Luna at 50% of their previous price. Over time, we see prices go low enough that it makes sense for most to buy usage as needed without there being a significant gap between what you get in a subscription and what you get in the API for a dollar spent.
(d) Tomorrow, we are adding more things to the subscription that won't draw on the usage, I won't reveal what that is yet.
I wanted to be transparent before all the big announcements tomorrow. Lots of new exciting things are coming to the subscriptions that will make it super compelling, but I wanted to make sure to share this change ahead of time so you can all understand it before we shower you with good news.
Codexingly,
Tibo
