Asked my dot to find emails in my personal inbox that fell through the cracks. Highly recommend! Felt an overwhelming surprise , relief, and joy when it found a documents that I should have passed onto my CPA, amongst a number of other smaller opportunities for following up on appointments and home vendors!

If you’re a company and you haven’t built a plugin you’re missing out on some significant distribution
point your codex at github.com/openai/mcp-extens… to start building a chatgpt plugin!

This is probably one of biggest single day leaps in math understanding, we are very fortunate to be witnessing these times
Completely unrelated to the rest of the ships today, but our models did solve some important math problems and the team documented it in the following blogpost. Remarkable new era of scientific progress. openai.com/index/sharing-ai-…

I was fortunate to get to work with the founders @sahillp , @vineetgoel92 and @rfurmaniak and even more lucky to call all of them good friends well before they decided to start Parafin! If you saw the three of them at work as closely as I got to, you would not be surprised at all that Parafin built such an amazing product. Thanks for letting me be a tiny part of the journey 🙏🏾. Investing in your smartest friends is always a good idea !
We are excited to share that Parafin is joining Stripe. Read the announcement from Sahill and Vineet:

Big and very exciting news: @parafinHQ is joining @stripe. We started Parafin in 2020 because the small businesses that power the economy were the hardest ones to finance. Six years later, with $3B+ funded to 60,000+ SMBs, we're taking the mission to Stripe's scale. Huge congratulations to our team, investors and supporters. To our customers: nothing changes about our commitment to you. It only gets better from here. More from me, @vineetgoel92, and the team

Proud of this. Open is the way.
Enterprise teams can now use open models like GLM-5.3 Flash and Kimi K3 natively in Codex and count spend against their OpenAI commit.

OpenAI going all in on platform + work + pareto for cost/intelligence seems very very strong

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.

If you have heard about India’s obsession with cricket, this guy contributed more to that love of the game than anyone else has in the history of the game
I’m excited to announce my partnership with OpenAI. We have some interesting things coming up, and I can’t wait to share them with you. I’ve always been curious... One question usually leads to another, and ChatGPT has certainly encouraged that habit. But it has also proved useful when I’ve needed to get things done, like planning my last trip with the family. That’s what I’m looking forward to with this partnership. Discovering what else I can do with ChatGPT, sharing what I find useful, and encouraging more people to give it a try with something they care about. A question, an idea, something you’ve always wanted to explore. There are so many places to start. Looking forward to exploring together. #Partnership

Many are saying
Astra is absurd.. Give it decently hard verifiable end to end tasks with the right tools and watch it just fly 😅

OpenAI's luna model is vastly underrated. The intelligence/cost ratio is crazy good.

Put Luna into your products and make every product intelligent
Luna is such insanely good value its not even funny. Basically doesn't make sense to meter tokens if you're offering luna in a product anymore.

Intelligence not worth metering 🔜
GPT-6 Luna is $0.10 / $0.50 per 1M tokens! We're soon going to have to switch to per billion token prices....

It’s great to see the team continue to push efficiency which we are then able to share with all of you! Excited for more ideas to be unblocked by this 🚀
Please welcome GPT-6 Sol and GPT-6 Luna to the GPT-6 universe. GPT-6 Sol and Luna build on the advances behind GPT-6 Astra, bringing much of its strengths into faster and more affordable models to support work at scale. We’ve also made caching and inference more efficient, and we’re passing the savings directly to you: 50% lower API prices for Sol and Luna compared with GPT‑5.6 promotional pricing.

Starting today, you can connect multiple accounts with most plugins in ChatGPT! 🎉 Bring context from your work and personal accounts into the same conversation. Connect your accounts in the plugin directory: chatgpt.com/plugins Devs: this works automatically, with no changes needed. But, to make the experience for users of your plugin even better, add a profile tool to your MCP server so ChatGPT can label the accounts: developers.openai.com/plugin…
