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

No Codex reset was announced that day.
Agreed
That was yesterday, today is DevDay. And it's all good news. I'm surprised we've kept it all under wraps. t.co/oR1Prs6pkT
And then I ran to Theo and whispered in his right ear “wake up Theo, it’s DevDay today”
👀
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.
Hello, this is Tibo, you’ve reached the wrong company. Let me redirect you to …
Announcing dots. Dots work 24/7 for you, learn from your feedback, have their own computer, browser and can be connected to over 4k apps in our ecosystem. They’re powered by Astra our best model yet. Included in your Pro plan, without drawing down on any of your usage. You can even call a dot while it’s working. We’re getting you started with your primary dot today and soon you’ll be able to create entire teams of them.
Announcing ChatGPT Space, a collection of new collaborative experiences right in ChatGPT. Edit rich notes with live visualizations together with others and your dots. Whether it’s a TODO list to delegate, a product plan or meeting notes. Working with others and your agents is seamless and they also be automatically kept up to date in the background. For developers, this is AGENTS.md taken one step further.
Introducing 6.1 Sol, near Astra intelligence at one fifth of the price of Astra and 95% cache read discount. It is an absolute workhorse. Combined with ultrafast for 8X speeded available today for Astra and coming soon for 6.1 Sol.
Decisions API, for lightning fast constrained decision making powered by Luna. Supports visual inputs, and tuned to be able to make decisions in less than a few hundreds of milliseconds end to end.
Launching a new Codex Cloud, much improved from last year. With configurable cloud environments, it’s impossible to go back to building on your laptop once you’ve taken the time to configure it. Agents API, the same tech powering all our cloud agents, including dots, is also now in preview and supports computer use. It allows you to build the same incredible products we are making available today.
Token traffic on responses API has increased 100X compared to today last year. Meanwhile the team improved reliability with 99.9% uptime and improving performance significantly.
Dots are included in all Pro, Business Premium and Enterprise plans. This includes the Pro 100 plan. We’ll be looking to further expand access soon.
You can now use your ChatGPT subscription directly in over 60 partners products. No little rules, you can just use all your included usage right there. This includes things such as Devin, OpenCode, Lovable, and many more. Sign in with ChatGPT and go.
We are opening up our platform and you can now build full native apps with plugin extensions, and ship them right in ChatGPT. We have over 1.2B weekly users and will surface relevant plugins right in the conversations.
Little summary t.co/HQ9Ut3cgSh
Live demos suffered from rolling out all the updates at the same time, but were committed to keep doing these live in the future. Almost all the things we announced will be available today. Can’t see what you will do with it.
You can now use your ChatGPT subscription directly in over 16 partners products. No little rules, you can just use all your included usage right there. This includes things such as Devin, OpenCode, Notion, and many more. Sign in with ChatGPT and go.
GPT-6.1 is a good model. And it’s unbelievably efficient. Included in all paid plans and on the API today. t.co/XateucqneE
