We’re making GPT-5 warmer and friendlier based on feedback that it felt too formal before. Changes are subtle, but ChatGPT should feel more approachable now. You'll notice small, genuine touches like “Good question” or “Great start,” not flattery. Internal tests show no rise in sycophancy compared to the previous GPT-5 personality. Changes may take up to a day to roll out, more updates soon.

Meta changed its policies so 1-800-ChatGPT won't work on WhatsApp after Jan 15, 2026. Luckily we have an app, website, and browser you can use instead to access ChatGPT.

We’ve heard your feedback that GPT-5 Thinking can sometimes take longer than you’d like.  Now Plus, Pro, and Business users can set the pace to match the moment. Select GPT-5 with Thinking in ChatGPT on web to toggle thinking time in the message composer. - Plus, Pro, Business have Standard (new default, balancing speed and intelligence) & Extended (previous default for Plus) - Pro also has Light (snappiest) & Heavy (deeper) Your thinking time selection will remain in place for future chats on web until you change it.

Updates to ChatGPT: You can now choose between “Auto”, “Fast”, and “Thinking” for GPT-5. Most users will want Auto, but the additional control will be useful for some people. Rate limits are now 3,000 messages/week with GPT-5 Thinking, and then extra capacity on GPT-5 Thinking mini after that limit. Context limit for GPT-5 Thinking is 196k tokens. We may have to update rate limits over time depending on usage. 4o is back in the model picker for all paid users by default. If we ever do deprecate it, we will give plenty of notice. Paid users also now have a “Show additional models” toggle in ChatGPT web settings which will add models like o3, 4.1, and GPT-5 Thinking mini. 4.5 is only available to Pro users—it costs a lot of GPUs. We are working on an update to GPT-5’s personality which should feel warmer than the current personality but not as annoying (to most users) as GPT-4o. However, one learning for us from the past few days is we really just need to get to a world with more per-user customization of model personality.

GPT-5 rollout updates: *We are going to double GPT-5 rate limits for ChatGPT Plus users as we finish rollout. *We will let Plus users choose to continue to use 4o. We will watch usage as we think about how long to offer legacy models for. *GPT-5 will seem smarter starting today. Yesterday, the autoswitcher broke and was out of commission for a chunk of the day, and the result was GPT-5 seemed way dumber. Also, we are making some interventions to how the decision boundary works that should help you get the right model more often. *We will make it more transparent about which model is answering a given query. *We will change the UI to make it easier to manually trigger thinking. *Rolling out to everyone is taking a bit longer. It’s a massive change at big scale. For example, our API traffic has about doubled over the past 24 hours… We will continue to work to get things stable and will keep listening to feedback. As we mentioned, we expected some bumpiness as we roll out so many things at once. But it was a little more bumpy than we hoped for!

A new AI-powered vision tool created an anatomy quiz, reviewed hand-drawn answers on a chalkboard, and provided feedback — all in real-time. For a fun challenge, it also wrote and sang a rhyme about finding the area of a triangle in a British accent. cbsn.ws/41pv4iZ

Mira deserves to take a break, she’s been sprinting at OAI for 5+ years, and also to get a chance to build 0-1 again. Everything doesn’t need to be a controversy.

Codex has transformed how OpenAI builds over the last few months. Have some great upcoming models too. Amazing work by the team!

By popular request: you can now branch conversations in ChatGPT, letting you more easily explore different directions without losing your original thread. Available now to logged-in users on web.

ChatGPT with voice is now available to all free users. Download the app on your phone and tap the headphones icon to start a conversation. Sound on 🔊

One of the most fun parts of OpenAI is watching people here level up so fast and do such excellent work. We are operating at a high level across many different disciplines and many of the people doing it have never done it before, and joined us at the beginning of their career. If you believe in people and give them a lot of responsibility and support (and pick the right people to bet on) you will be surprised on the upside more often than you think. I would love to see more companies operate this way and think we would all benefit. (This was also one of the most fun parts of startup investing.)

Sora 2 is here.

You can now interrupt long-running queries and add new context without restarting or losing progress. This is especially useful for refining deep research or GPT-5 Pro queries as the model will adjust its response with your new requirements. Just hit update in the sidebar and type in any additional details or clarifications.

openai’s real advantage is that they almost always close the product loop. every breakthrough finds a consumer form. chatgpt crystallized gpt. sora now has a social app that locks in video gen. nobody else even with great tech like google has managed to consistently do this. that discipline deserves credit.

i love the openai team so much

We've learned a lot from the ChatGPT research preview and have been making important updates based on user feedback. ChatGPT will be coming to our API and Microsoft's Azure OpenAI Service soon. Sign up for updates here: share.hsforms.com/1u4goaXwDR…

Big day for desktops. Advanced Voice is now available in the macOS and Windows desktop apps. openai.com/chatgpt/download/

way back on friday, the high score on "humanity's last exam" was o3-mini-high at 13%. now on sunday, deep research gets 26.6%.

12 days. 12 livestreams. A bunch of new things, big and small. 12 Days of OpenAI starts tomorrow.

About 650 / 770 signed at this moment. As people start waking up, more will come. All the efforts started after 1:30 AM, 500+ within two hours and all of this after 2 crazy days with very little sleep.

🧵Today we’re sharing more details about improvements of the default GPT-5 model in responding to sensitive conversations around potential mental health emergencies and emotional reliance. These changes reflect the careful work of many teams within OpenAI and close consultation with experts - including more than 170 mental health clinicians.

We've received incredible feedback since launching our new browser, ChatGPT Atlas, yesterday. We're really focused on building the best product for all of you, and since launch, the team has been heads down making it better. In the spirit of transparency, these are the very short-term things we're fixing over the coming weeks, though some may take a little longer (profiles, tab groups, opt-in ad blocker). If you have more suggestions for us, let us know! There are other things we're working on, but those may involve partners, and we've left those off this list

OPENAI ROADMAP UPDATE FOR GPT-4.5 and GPT-5: We want to do a better job of sharing our intended roadmap, and a much better job simplifying our product offerings. We want AI to “just work” for you; we realize how complicated our model and product offerings have gotten. We hate the model picker as much as you do and want to return to magic unified intelligence. We will next ship GPT-4.5, the model we called Orion internally, as our last non-chain-of-thought model. After that, a top goal for us is to unify o-series models and GPT-series models by creating systems that can use all our tools, know when to think for a long time or not, and generally be useful for a very wide range of tasks. In both ChatGPT and our API, we will release GPT-5 as a system that integrates a lot of our technology, including o3. We will no longer ship o3 as a standalone model. The free tier of ChatGPT will get unlimited chat access to GPT-5 at the standard intelligence setting (!!), subject to abuse thresholds. Plus subscribers will be able to run GPT-5 at a higher level of intelligence, and Pro subscribers will be able to run GPT-5 at an even higher level of intelligence. These models will incorporate voice, canvas, search, deep research, and more.

GPT-5-Codex is 10x faster for the easiest queries, and will think 2x longer for the hardest queries that benefit most from more compute.

ChatGPT is the most consequential consumer product of our time. 10% of the world uses it weekly. It generates billions in revenue (less than three years after launch). It's the fastest-growing product in history (by far). In his first in-depth interview, Head of ChatGPT @nickaturley shares: - How ChatGPT's success was an accident—it began as a hackathon project they planned to shut down after the holidays - How they picked the $20/month price point—by running a Van Westendorp willingness-to-pay survey with a Google Form (a pricing strategy everyone has since copied) - What created ChatGPT's rare "smiling" retention curve - Why ChatGPT was originally called "ChatWithGPT3.5" - "Is it maximally accelerated?" - the philosophy driving OpenAI's relentless pace - Nick's vision for ChatGPT evolving beyond just a chat interface - The impact ChatGPT will have on SEO and product growth - How TikTok comments became a primary user research channel early on - Much more Listen now 👇 • YouTube: piped.video/ixY2PvQJ0To • Spotify: open.spotify.com/episode/0ki… • Apple: podcasts.apple.com/us/podcas… Thank you to our wonderful sponsors for supporting the podcast: 🏆 @orkesio—The enterprise platform for reliable applications and agentic workflows: orkes.io/ 🏆 @TrustVanta—Automate compliance.

Celebrated 200m just about a year ago. now, as we approach 700m, it feels like an even bigger responsibility and a privilege to work on ChatGPT and at OAI.

lol if i could go back in time two years i would slightly amend this. you can definitely just do stuff, but then sometimes it takes over your life.

OpenAI o1 is now out of preview in ChatGPT. What’s changed since the preview? A faster, more powerful reasoning model that’s better at coding, math & writing. o1 now also supports image uploads, allowing it to apply reasoning to visuals for more detailed & useful responses.

Generalists are useful, but it’s not enough to be smart. Advances come from specialists, whether human or machine. To have an edge, agents need specific expertise, within specific companies, built on models trained on specific data. We call this Specific Intelligence. It's what we're building at Applied Compute. We unlock the latent knowledge inside a company, use it to train custom models, and deploy an in-house agent workforce that reports to your team. We work with sophisticated companies that have already captured early gains from general models, like @cognition, @DoorDash, and @mercor_ai. They’re pulling even further ahead with proprietary in-house agents that don’t need to wait for the next public model release. Together, we are building and validating models and agents in days instead of months, achieving state-of-the-art performance on customer evals. Our team has high density and low latency. Our founders all worked on different parts of this problem while they were researchers at OpenAI — @ypatil125 as a key member on the agentic software engineer effort (Codex), @rhythmrg as a core contributor to the first RL-trained reasoning model (o1), and @lindensli as a core contributor on ML systems and infrastructure for RL training. Two-thirds of the team are former founders, and everyone brings a deep technical background, from top AI researchers to Math Olympiad winners. We are backed by $80M in funding from Benchmark, Sequoia, Lux, Elad Gil, Victor Lazarte, Omri Casspi, and others. With their support, we are growing the team, scaling deployments, and bringing to market the first generation of agent workforces built on specific models. In short: 1. We are building Specific Intelligence for specific work at specific companies. 2. That will power in-house agent workforces to support their human bosses. 3. That in turn will unlock AI’s full potential through humanity’s greatest engine of progress: thriving corporations in a free market.

Starting today, memory in ChatGPT can now reference all of your past chats to provide more personalized responses, drawing on your preferences and interests to make it even more helpful for writing, getting advice, learning, and beyond.

🔪 chatgpt refusals & warnings 🙅‍♂️🙅‍♀️ has chatgpt ever refused to give you what you want for no good reason? or reasons you disagree with? please let us know and we'll do our best to fix it!

the openai team is executing just ridiculously well at so many things right now, the coming months and years should be amazing (a lotta stuff is messy and very broken too of course)

OpenAI is growing as fast as a promising new startup, but they're already huge. I can't remember ever having seen this before.

We’re starting to roll out the ability to search through your chat history on ChatGPT web. Now you can quickly & easily bring up a chat to reference, or pick up a chat where you left off.

Excited to share what @billpeeb @_tim_brooks and my team has been working on for the past year! Our text-to-video model Sora can generate videos of complex scenes up to a minute long. We're excited about making this step toward AI that can reason about the world like we do. openai.com/sora
