OpenAI to retire whole host of legacy models in ChatGPT, including 4o

OpenAI is binning previously popular legacy models, used by 0.1% of users. (Picture: generated)
Brought back by popular demand after the turbulent release of GPT-5, OpenAI is now sending off the GPT‑4o, GPT‑4.1, GPT‑4.1 mini, OpenAI o4-mini and GPT-5 models on February 13th.

The reason for bringing them back was how clinical and cerebral, and less friendly GPT-5 had gotten, leading to a very public backlash.

After this, OpenAI spent a lot of time thinking about personality and customization — leading to GPT-5.2, which now has the overwhelming majority of users.

The previously very popular 4o model is now only used by 0.1% of users.

In their announcement today, OpenAI also says they are making progress towards a more creative version of GPT for adults, having rolled out age prediction earlier this month.

OpenAI launches Prism, a research and collaboration tool for scientists

Prism is billed as a one stop shop for researchers, combining what was previously spread far and wide. (Picture: OpenAI)
Scientists are often plagued by having to use different platforms and apps for seemingly mundane things.

That’s where OpenAI’s new service comes in — as a LaTeX-native interface, it combines the paper writing in the same space as it does equations, references and «surrounding context.»

Of course there is a GPT-5.2 engine right there, so it’s easy to cross-reference and check for originality, find citations and proofread — and it’s a fairly nice research assistant, to boot.

Prism is available as of now for anyone who has a personal account with OpenAI.

OpenAI says ChatGPT increasingly used in hard science

Growing rapidly; ever more people are using ChatGPT in scientific fields. (Picture: OpenAI)
In a report shared with Axios, OpenAI is touting ChatGPT’s prowess as a research assistant, saying it has «progressed past competition level performance toward mathematical discovery.»

The scales are still low — with 1.3 million users discussing «advanced hard science,» and an average of 8.3 million weekly messages on the topics.

To put this into perspective, an October, 2025, survey from OpenAI said that 0.15% of ChatGPT users engaged in conversations on self-harm and suicide, or roughly 1.2 million customers.

ChatGPT 5.2 found to cite Grokipedia

Always check your sources, and you might notice some creep. (Picture: Generated)
Elon Musk’s and xAI’s Grok-powered version of Wikipedia, Grokipedia, is littered with falsehoods, white supremacy cheerleading and has a known far-right, pro-conspiracy bias.

That does not exclude it from being used as a source for ChatGPT 5.2, according to The Guardian, who found it cited the «encyclopedia» in responses to nine out of a dozen test questions.

The questions weren’t about the insurrection, Trump media bias or about HIV/AIDS, where Grokipedia has a known bias, but rather more obscure ones on Iranian funding and specific Holocaust deniers.

This illustrates how adverse groups, such as Russia’s Pravda, can flood the internet with falsehoods and have it picked up by an LLM scraping for content, and then later get picked up in responses.

— We apply safety filters to reduce the risk of surfacing links associated with high-severity harms, and ChatGPT clearly shows which sources informed a response through citations, OpenAI told The Guardian.

It’s official: OpenAI rolls out age-gating globally

OpenAI will use AI to verify your age and serve a less harmful experience, but it does make mistakes. (Picture: generated)
Last month offered a sneak peek at OpenAI’s support page for «age prediction,» and now they are ready to go live.

Age prediction works by taking in several factors such as usage time, account age and the time the user is active.

It is developed «in dialogue» with experts from the American Psychological Association, ConnectSafely, and Global Physicians Network⁠.

After several wrongful death lawsuits involving teens, disturbing mental health conversations and stating that principles are in conflict, OpenAI was more or less forced into doing something on both teen use and parental controls.

Those deemed under 18 by the AI will be served a vanilla version of ChatGPT without beauty standards, violence or romantic role-play, to name a few examples.

If someone gets wrongfully lobbed into the teen experience, and it does make mistakes, they can upload a selfie for proper verification through Persona.

OpenAI to start «public» advertising tests on ChatGPT

What ads will look like If you click it, you can query it for more information. (Picture: OpenAI)
The tests will happen «during the coming weeks» for ChatGPT Free and Go tiers — and will try to put relevant, clearly labeled ads beneath GPT responses, OpenAI announces.

OpenAI says they won’t share your data or conversation to advertisers, and will «maintain a high standard» where you can turn off personalization if you want to.

They won’t be shown to under-18s, they say, nor will they show on sensitive topics, such as physical health, mental health or politics.

The neat part of the coming ads is that you click on them and query them for further detail, which is a feature not found in traditional advertising.

The Financial times estimates that OpenAI can earn somewhere around the «low billions» from advertising.

Ads won’t be shown for paying tiers, such as Plus, Pro and Enterprise.

ChatGPT Go expands globally, comes to the United States

A little more dollars for a little more usage. It’s a simple plan, yet effective. (Picture: generated).
ChatGPT Go was first launched as a cheap way to access more GPT queries in India in August, 2025, for around $5. Now, the subscription has become popular enough to expand globally to every market where OpenAI is active.

The idea is that for a just little more money, $8 in the USA, you can get ten times the queries, ten times the file use, and ten times the image generations compared to the free plan.

OpenAI says that since the introduction of the Go subscription tier, they have seen extensive everyday use in tasks such as writing, learning, image generations and problem-solving.

Along with the Free tier, ChatGPT Go will be showing ads once they are ready.

OpenAI announces ChatGPT for healthcare, clinicians and institutions

From scientific discoveries to sifting through millions of peer-reviewed studies, doctors armed with ChatGPT can lead to better outcomes, OpenAI says. (Picture: Adobe)
Just a couple of days ago, OpenAI announced health tools for consumers and patients — and now it’s coming for the doctors and hospitals, with a HIPAA compliant AI product.

ChatGPT for healthcare can instantly draw upon millions of peer-reviewed research studies, health guidance and clinical guidelines, and can help clinicians reason through cases with greater confidence, OpenAI says.

We also know from the earlier days of ChatGPT that it can have an uncanny ability to compare millions of medical images to support a diagnosis — by doctors, not patients.

230 million users every month have health questions for ChatGPT, and now they are building a «Secure Enclave» for ChatGPT Health.

The service will most importantly have access to your medical journals, but also patches into some popular services, like Apple Health, Function, MyFitnessPal, Weight Watchers, Instacart and Peloton.

OpenAI sees 40 million daily prompts about health care

Ever more people are asking ChatGPT medical questions, OpenAI finds. (Picture: Adobe)
Even after restricting some health care questions, health prompts are booming on ChatGPT, according to a new OpenAI survey.

5% of all questions globally are about health, one in four questions per week are the same — and that adds up in aggregate to a really big number.

It’s not just normal users curious about care that ask the chatbot, but health care professionals, too. Of these, 46% of nurses, 41% of pharmacy workers, and 48% of physicians say they use ChatGPT once per week or more.

The questions usually roll in outside of normal clinical hours, and happen especially in health care deserts, OpenAI says.

OpenAI has great ambitions for the field, and says in their report that the next boundary to cross is for robotic wet labs and physical AI.

They also tick off a long list of how OpenAI can aid in scientific discovery and drug development.

OpenAI drops yearly review on ChatGPT — but only for English countries

Flashy cards and bells and whistles, as ChatGPT walks you through your year. (Picture: OpenAI)
For many, this year has been one long engagement with AI chatbots, and ChatGPT is there to wrap it up with you.

TechCrunch has spotted a flashy, card- and graphics-based «Your Year with ChatGPT» getting rolled out this holiday season.

It’s supposed to be a «lightweight, privacy-forward, and user-controlled» little romp through the year.

The trick is that you need an English account for those, but at least it works from the free tiers all the way up to Pro — with a minimum of engagement, wile Enterprise and Edu accounts are left out.

Everyone else can turn on a slightly less flashy rehash of your GPT usage for the year by simply typing «Show me my year with ChatGPT» right in the chat window, and it will offer a nice little summary of your usage.

It’s not fancy or flashy, but it might turn out a smile or two as you remember some epic AI moments of the year gone by.

OpenAI quietly rolls out age controls in ChatGPT

ChatGPT's "teen experience" is quietely rolling out.
The «teen experience» on ChatGPT is still quite useful, but lacks insensitive interactions. (Picture: generated)
In order to limit sensitive content for teens, such as graphic violence, harmful viral challenges, sexual or romantic role-play and impossible beauty standards, ChatGPT now assesses their users’ age.

The age-gating is done in the background magic of the AI, determining general topics the user talks about, or things like the times of day the user is on ChatGPT.

It will not require mass-identification of the user base, unless you want to complain about getting age-gated to the «teen experience.»

To do this, you can upload a selfie to ChatGPT in the Account Settings, by clicking on Age Verification and selecting Verify Age.

From here, ChatGPT can determine your age from a simple selfie, but if that is not enough, you might have to offer up a Government ID.

On OpenAI’s Age prediction page, it says «this feature is still rolling out, so you might not see it yet depending on where you live.»

OpenAI introduces more granular control of their personalities

New personality settings offer detailed controls for ChatGPT's personality.
New settings in ChatGPT lets you tweak the bot’s personality even more. (Picture: Screenshot)
Since GPT-5 it’s been possible to get ChatGPT to take on a lot of different personalities in how it interacts with the user.

Now, the controls for this has become much more detailed, with added «characteristics.»

You can control to what extent you want your chatbot to be Warm or Enthusiastic, and how much it uses Emoji and Headers & Lists, in addition to using a different «main voice and tone.»

The new settings are available to all users in the «Personalization» setting.

This is in line with OpenAI’s policy of making ChatGPT more personalized and customized for the end user — and we can probably expect more of this in the future.

ChatGPT now has an Apple Music app

You can now find Apple Music in the App list for ChatGPT. (Picture: Screenshot)
After days of rumors, Apple Music is now available as an app inside ChatGPT.

That means you can ask ChatGPT to create playlists, find songs, albums and artists — which can be helpful for those faint songs you can only describe from memory, or for recommending similar songs in the same lane.

The app can even create complex playlists based on natural language and preferences right in ChatGPT, and will give you an option to add it to your library — always asking politely first.

To add it, go to Settings->Apps->Browse apps in the ChatGPT app, and add it from the list. You will then have access by typing /Apple Music.

You will be asked to sign in to Apple Music from your account, and non-subscribers will only be able to listen to short previews of songs.
