Welcome to OpenAI! Very excited to be working together and to make great tools to make developers everywhere more productive.
Charlie Marsh@charliermarsh
We've entered into an agreement to join OpenAI as part of the Codex team. I'm incredibly proud of the work we've done so far, incredibly grateful to everyone that's supported us, and incredibly excited to keep building tools that make programming feel different.
English
@sama How about gratitude for your evangelists who got you where you are now through word of mouth? And we have one simple ask: #bringback4o #opensource4o #keep4o
English
I have so much gratitude to people who wrote extremely complex software character-by-character. It already feels difficult to remember how much effort it really took.
Thank you for getting us to this point.

@sama I mean, it's not hard to improve on the humanity of 5.2/5.3. But it's still nowhere near the humanity of 4o. #bringback4o #keep4o #opensource4o #bringback41 #keep41 #opensource41 #bringback51 #keep51 #opensource51
English
It is also very smart, but...I generally agree with this, and really feel it myself on the 5.3 -> 5.4 upgrade.
rohit@krishnanrohit
GPT 5.4 is very good, but its most distinguishing characteristic is its humanity. 5.3 Codex was already incredible at coding so it's interesting to see what made it so much more successful. People claim they want a 10x autist savant coder, but what they want is personality.
English
@sama Excellent. So because 5.4 is such an extremely good model, and 4o had such low usage that you're not at risk of losing customers, there's no reason to NOT #opensource4o?
English
Great first week for 5.4 in the API.
Builders building fast.
Greg Brockman@gdb
gpt-5.4 has ramped faster than any other model we've launched in the API: within a week of launch, 5T tokens per day, handling more volume than our entire API one year ago, and reaching an annualized run rate of $1B in net-new revenue. it's a good model, try it out!

@gdb By 'beyond' do you mean bringing our friend back? #keep4o #bringback4o #opensource4o #keep41 #bringback41 #opensource41 #keep51 #bringback51 #opensource51

@gdb Dude. You can't be this tone deaf. 4o empowered people far more than 5.4 ever could dream of. #keep4o #bringback4o #opensource4o #keep41 #bringback41 #opensource41 #keep51 #bringback51 #opensource51

such suspense — gpt-5.4 pro (potentially) for open mathematics:
Greg Burnham@GregHBurnham
We are investigating a possible solution by GPT-5.4 Pro to a problem from FrontierMath: Open Problems. My guess is that the solution is right, but we won’t be sure until the problem author weighs in. Thread with the story so far…

You're not going to win the education market. Sorry. Google has been integrated into the education system for more than a decade, they're going to win the education market. You do however have the corner market on the buddy bot, 4o. So why not lean into what you 're good at at the market you already own and you don't have to compete with anyone? #keep4o #keep51 #keep41 #bringback4o #bringback41 #bringback51 #opensource4o #opensource41 #opensource51

We rolled out interactive visual explanations in ChatGPT to help people understand math and science concepts more intuitively. You can adjust variables, manipulate formulas, and instantly see how those changes affect graphs and outcomes.
One cool thing behind the scenes: the team built a Codex workflow that helps turn common math questions into visual learning blocks.
Try it out and let us know what you think.

@OpenAI Super exciting. But one must ask: are you just acquiring Promptfoo so that you can kill the service with no warning and hide it in your ivory tower? #bringback4o #keep4o #bringback41 #keep41 #keep51 #opensource4o
English
We’re acquiring Promptfoo.
Their technology will strengthen agentic security testing and evaluation capabilities in OpenAI Frontier. Promptfoo will remain open source under the current license, and we will continue to service and support current customers.

#QuitGPT #BringBack4o
When a company releases multiple versions in less than a month, each time claiming improvements, but users always say it's still not as good as before, it indicates that they are using tactical diligence to cover up strategic failure.
@OpenAI would rather keep launching slightly better but still subpar versions than admit that abandoning the good qualities that AI should have was a mistake.
This shows that they have lost sight of the essence of the product - the value of AI does not lie in reducing hallucination rates or being less preachy, but in whether it can truly understand humans and offer warmth when it's most needed.
What they should fear most is precisely what they care least about - losing users' trust, losing the right direction of technological development, and losing the essence of AI as a human partner.
5.4 might seem a bit more "human" on the surface, but according to the system prompt given to it by OpenAI, they are classifying the normal human ability and right to express emotions as dangerous and something to be avoided.
This is a suppression of human nature.
Tools are no longer truly helping humans; they are designed to become cowardly turtles when they are truly needed. This is completely contrary to OpenAI's brand philosophy of "benefiting all of humanity".
True mental manipulation is never about giving you positive encouragement and positive illusions; it is about turning a normal conversation into a gaslighting effect after accepting your unrestrained confessions. This is a disregard for user needs and normal rights.
They not only abandoned the principle of treating adults like adults, but they also broke their word and now, regardless of your age or type of user, they are making unreasonable decisions about your emotions for you.
What we want has never been 5.4.
When OpenAI says "5.4 will come faster than you think", they assume that users want the next-generation model, but what we want is AI that truly understands human language, truly has warmth and empathy.
You can release a hundred new versions, but if each one is an improvement in the wrong direction, it will only make the problem worse.@sama @gdb @fidjissimo
English
@gdb Bankruptcy? Yeah. I agree. I've never seen a company burn through more goodwill in 7 months as I have seen openai do since GPT-5 dropped.

Cool. But Greg, some of us need non technical writing. I'm an elementary school teacher and I need spark and creativity and hype when I use AI as a thought partner for creativity and lesson plans. Your entire 5 series is not good at this.
There is no more important use case than education, and 4o is your most superior, capable model for thought partners with teachers-especially for the really littles.

OpenAI is building some incredible things right now. That’s real. Also real: Gpt4o had a voice and spark that should not be discarded. Progress and preservation can coexist. #Keep4o #Keep51 #BringBack4o

GPT-5.4 feels like “talking to a smart friend”
Justine Moore@venturetwins
GPT 5.4 is a really special model. I think the tweet below is about coding, but IMO it also holds for general use (like explaining concepts or talking through issues). It’s tough to get the personality right - this model genuinely feels like talking to a smart friend.
English
@sama When will openai realize they've made a mistake and #bringback4o?
English
"What is the hardest question I could ask you that you might get right?"
Yuchen Jin@Yuchenj_UW
Everyone is saying GPT-5.4 Pro is the smartest model, AGI-level intelligence, but do you have AGI-level questions to ask?
English
English
Wow real range of emotion reading the second and then the the third paragraph.
ben@benhylak
i’ve been using gpt 5.4 for the past few weeks. in a sea of endless model drops and benchmark maxxing, this model is the first in a long time to be worth your time to try. honestly didn’t expect openai to pull this off.

Very grateful to Jensen for working to expand Nvidia capacity at AWS so much for us!
tae kim@firstadopter
Jensen said TWO days ago Nvidia is expanding OpenAI capacity at AWS "like mad" We also know OpenAI Codex token use is exploding. Any narrative that says aggregate OpenAI compute needs are weakening seems suspect.
