ChatGPT, OpenAI’s text-generating AI chatbot, has taken the world by storm since its launch in November 2022. What started as a tool to supercharge productivity through writing essays and code with short text prompts has evolved into a behemoth with 300 million weekly active users.
2024 was a big year for OpenAI, from its partnership with Apple for its generative AI offering, Apple Intelligence, the release of GPT-4o with voice capabilities, and the highly-anticipated launch of its text-to-video model Sora.
OpenAI also faced its share of internal drama, including the notable exits of high-level execs like co-founder and longtime chief scientist Ilya Sutskever and CTO Mira Murati. OpenAI has also been hit with lawsuits from Alden Global Capital-owned newspapers alleging copyright infringement, as well as an injunction from Elon Musk to halt OpenAI’s transition to a for-profit.
In 2025, OpenAI is battling the perception that it’s ceding ground in the AI race to Chinese rivals like DeepSeek. The company has been trying to shore up its relationship with Washington as it simultaneously pursues an ambitious data center project, and as it reportedly lays the groundwork for one of the largest funding rounds in history.
Below, you’ll find a timeline of ChatGPT product updates and releases, starting with the latest, which we’ve been updating throughout the year. If you have any other questions, check out our ChatGPT FAQ here.
Timeline of the most recent ChatGPT updates
March 2025
ChatGPT has upgraded its image-generation feature
OpenAI on Tuesday rolled out a major upgrade to ChatGPT’s image-generation capabilities: ChatGPT can now use the GPT-4o model to generate and edit images and photos directly. The feature went live earlier this week in ChatGPT and Sora, OpenAI’s AI video-generation tool, for subscribers of the company’s Pro plan, priced at $200 a month, and will be available soon to ChatGPT Plus subscribers and developers using the company’s API service. The company’s CEO Sam Altman said on Wednesday, however, that the release of the image generation feature to free users would be delayed due to higher demand than the company expected.
OpenAI announces leadership updates
Brad Lightcap, OpenAI’s chief operating officer, will lead the company’s global expansion and manage corporate partnerships as CEO Sam Altman shifts his focus to research and products, according to a blog post from OpenAI. Lightcap, who previously worked with Altman at Y Combinator, joined the Microsoft-backed startup in 2018. OpenAI also said Mark Chen would step into the expanded role of chief research officer, and Julia Villagra will take on the role of chief people officer.
OpenAI’s AI voice assistant now has advanced feature
OpenAI has updated its AI voice assistant with improved chatting capabilities, according to a video posted on Monday (March 24) to the company’s official media channels. The update enables real-time conversations, and the AI assistant is said to be more personable and interrupts users less often. Users on ChatGPT’s free tier can now access the new version of Advanced Voice Mode, while paying users will receive answers that are “more direct, engaging, concise, specific, and creative,” a spokesperson from OpenAI told TechCrunch.
OpenAI and Meta have separately engaged in discussions with Indian conglomerate Reliance Industries regarding potential collaborations to enhance their AI services in the country, per a report by The Information. One key topic being discussed is Reliance Jio distributing OpenAI’s ChatGPT. Reliance has proposed selling OpenAI’s models to businesses in India through an application programming interface (API) so they can incorporate AI into their operations. Meta also plans to bolster its presence in India by constructing a large 3GW data center in Jamnagar, Gujarat. OpenAI, Meta, and Reliance have not yet officially announced these plans.
OpenAI faces privacy complaint in Europe for chatbot’s defamatory hallucinations
Noyb, a privacy rights advocacy group, is supporting an individual in Norway who was shocked to discover that ChatGPT was providing false information about him, stating that he had been found guilty of killing two of his children and trying to harm the third. “The GDPR is clear. Personal data has to be accurate,” said Joakim Söderberg, data protection lawyer at Noyb, in a statement. “If it’s not, users have the right to have it changed to reflect the truth. Showing ChatGPT users a tiny disclaimer that the chatbot can make mistakes clearly isn’t enough. You can’t just spread false information and in the end add a small disclaimer saying that everything you said may just not be true.”
OpenAI upgrades its transcription and voice-generating AI models
OpenAI has added new transcription and voice-generating AI models to its APIs: a text-to-speech model, “gpt-4o-mini-tts,” that delivers more nuanced and realistic sounding speech, as well as two speech-to-text models called “gpt-4o-transcribe” and “gpt-4o-mini-transcribe”. The company claims they are improved versions of what was already there and that they hallucinate less.
OpenAI has launched o1-pro, a more powerful version of its o1
OpenAI has introduced o1-pro in its developer API. OpenAI says its o1-pro uses more computing than its o1 “reasoning” AI model to deliver “consistently better responses.” It’s only accessible to select developers who have spent at least $5 on OpenAI API services. OpenAI charges $150 for every million tokens (about 750,000 words) input into the model and $600 for every million tokens the model produces. It costs twice as much as OpenAI’s GPT-4.5 for input and 10 times the price of regular o1.
OpenAI research lead Noam Brown thinks AI “reasoning” models could’ve arrived decades ago
Noam Brown, who heads AI reasoning research at OpenAI, thinks that certain types of AI models for “reasoning” could have been developed 20 years ago if researchers had understood the correct approach and algorithms.
OpenAI says it has trained an AI that’s “really good” at creative writing
OpenAI CEO Sam Altman said, in a post on X, that the company has trained a “new model” that’s “really good” at creative writing. He posted a lengthy sample from the model given the prompt “Please write a metafictional literary short story about AI and grief.” OpenAI has not extensively explored the use of AI for writing fiction. The company has mostly concentrated on challenges in rigid, predictable areas such as math and programming. And it turns out that it might not be that great at creative writing at all.
OpenAI rolled out new tools designed to help developers and businesses build AI agents — automated systems that can independently accomplish tasks — using the company’s own AI models and frameworks. The tools are part of OpenAI’s new Responses API, which enables enterprises to develop customized AI agents that can perform web searches, scan through company files, and navigate websites, similar to OpenAI’s Operator product. The Responses API effectively replaces OpenAI’s Assistants API, which the company plans to discontinue in the first half of 2026.
OpenAI reportedly plans to charge up to $20,000 a month for specialized AI ‘agents’
OpenAI intends to release several “agent” products tailored for different applications, including sorting and ranking sales leads and software engineering, according to a report from The Information. One, a “high-income knowledge worker” agent, will reportedly be priced at $2,000 a month. Another, a software developer agent, is said to cost $10,000 a month. The most expensive rumored agents, which are said to be aimed at supporting “PhD-level research,” are expected to cost $20,000 per month. The jaw-dropping figure is indicative of how much cash OpenAI needs right now: The company lost roughly $5 billion last year after paying for costs related to running its services and other expenses. It’s unclear when these agentic tools might launch or which customers will be eligible to buy them.
ChatGPT can directly edit your code
The latest version of the macOS ChatGPT app allows users to edit code directly in supported developer tools, including Xcode, VS Code, and JetBrains. ChatGPT Plus, Pro, and Team subscribers can use the feature now, and the company plans to roll it out to more users like Enterprise, Edu, and free users.
ChatGPT’s weekly active users doubled in less than 6 months, thanks to new releases
According to a new report from VC firm Andreessen Horowitz (a16z), OpenAI’s AI chatbot, ChatGPT, experienced solid growth in the second half of 2024. It took ChatGPT nine months to increase its weekly active users from 100 million in November 2023 to 200 million in August 2024, but it only took less than six months to double that number once more, according to the report. ChatGPT’s weekly active users increased to 300 million by December 2024 and 400 million by February 2025. ChatGPT has experienced significant growth recently due to the launch of new models and features, such as GPT-4o, with multimodal capabilities. ChatGPT usage spiked from April to May 2024, shortly after that model’s launch.
February 2025
OpenAI cancels its o3 AI model in favor of a ‘unified’ next-gen release
OpenAI has effectively canceled the release of o3 in favor of what CEO Sam Altman is calling a “simplified” product offering. In a post on X, Altman said that, in the coming months, OpenAI will release a model called GPT-5 that “integrates a lot of [OpenAI’s] technology,” including o3, in ChatGPT and its API. As a result of that roadmap decision, OpenAI no longer plans to release o3 as a standalone model.
ChatGPT may not be as power-hungry as once assumed
A commonly cited stat is that ChatGPT requires around 3 watt-hours of power to answer a single question. Using OpenAI’s latest default model for ChatGPT, GPT-4o, as a reference, nonprofit AI research institute Epoch AI found the average ChatGPT query consumes around 0.3 watt-hours. However, the analysis doesn’t consider the additional energy costs incurred by ChatGPT with features like image generation or input processing.
OpenAI now reveals more of its o3-mini model’s thought process
In response to pressure from rivals like DeepSeek, OpenAI is changing the way its o3-mini model communicates its step-by-step “thought” process. ChatGPT users will see an updated “chain of thought” that shows more of the model’s “reasoning” steps and how it arrived at answers to questions.
You can now use ChatGPT web search without logging in
OpenAI is now allowing anyone to use ChatGPT web search without having to log in. While OpenAI had previously allowed users to ask ChatGPT questions without signing in, responses were restricted to the chatbot’s last training update. This only applies through ChatGPT.com, however. To use ChatGPT in any form through the native mobile app, you will still need to be logged in.
OpenAI unveils a new ChatGPT agent for ‘deep research’
OpenAI announced a new AI “agent” called deep research that’s designed to help people conduct in-depth, complex research using ChatGPT. OpenAI says the “agent” is intended for instances where you don’t just want a quick answer or summary, but instead need to assiduously consider information from multiple websites and other sources.
February 2025
OpenAI used a subreddit to test AI persuasion
OpenAI used the subreddit r/ChangeMyView to measure the persuasive abilities of its AI reasoning models. OpenAI says it collects user posts from the subreddit and asks its AI models to write replies, in a closed environment, that would change the Reddit user’s mind on a subject. The company then shows the responses to testers, who assess how persuasive the argument is, and finally OpenAI compares the AI models’ responses to human replies for that same post.
OpenAI launches o3-mini, its latest ‘reasoning’ model
OpenAI launched a new AI “reasoning” model, o3-mini, the newest in the company’s o family of models. OpenAI first previewed the model in December alongside a more capable system called o3. OpenAI is pitching its new model as both “powerful” and “affordable.”
ChatGPT’s mobile users are 85% male, report says
A new report from app analytics firm Appfigures found that over half of ChatGPT’s mobile users are under age 25, with users between ages 50 and 64 making up the second largest age demographic. The gender gap among ChatGPT users is even more significant. Appfigures estimates that across age groups, men make up 84.5% of all users.
OpenAI launches ChatGPT plan for US government agencies
OpenAI launched ChatGPT Gov designed to provide U.S. government agencies an additional way to access the tech. ChatGPT Gov includes many of the capabilities found in OpenAI’s corporate-focused tier, ChatGPT Enterprise. OpenAI says that ChatGPT Gov enables agencies to more easily manage their own security, privacy, and compliance, and could expedite internal authorization of OpenAI’s tools for the handling of non-public sensitive data.
More teens report using ChatGPT for schoolwork, despite the tech’s faults
Younger Gen Zers are embracing ChatGPT, for schoolwork, according to a new survey by the Pew Research Center. In a follow-up to its 2023 poll on ChatGPT usage among young people, Pew asked ~1,400 U.S.-based teens ages 13 to 17 whether they’ve used ChatGPT for homework or other school-related assignments. Twenty-six percent said that they had, double the number two years ago. Just over half of teens responding to the poll said they think it’s acceptable to use ChatGPT for researching new subjects. But considering the ways ChatGPT can fall short, the results are possibly cause for alarm.
OpenAI says it may store deleted Operator data for up to 90 days
OpenAI says that it might store chats and associated screenshots from customers who use Operator, the company’s AI “agent” tool, for up to 90 days — even after a user manually deletes them. While OpenAI has a similar deleted data retention policy for ChatGPT, the retention period for ChatGPT is only 30 days, which is 60 days shorter than Operator’s.
OpenAI is launching a research preview of Operator, a general-purpose AI agent that can take control of a web browser and independently perform certain actions. Operator promises to automate tasks such as booking travel accommodations, making restaurant reservations, and shopping online.
Operator, OpenAI’s agent tool, could be released sooner rather than later. Changes to ChatGPT’s code base suggest that Operator will be available as an early research preview to users on the $200 Pro subscription plan. The changes aren’t yet publicly visible, but a user on X who goes by Choi spotted these updates in ChatGPT’s client-side code. TechCrunch separately identified the same references to Operator on OpenAI’s website.
OpenAI tests phone number-only ChatGPT signups
OpenAI has begun testing a feature that lets new ChatGPT users sign up with only a phone number — no email required. The feature is currently in beta in the U.S. and India. However, users who create an account using their number can’t upgrade to one of OpenAI’s paid plans without verifying their account via an email. Multi-factor authentication also isn’t supported without a valid email.
ChatGPT now lets you schedule reminders and recurring tasks
ChatGPT’s new beta feature, called tasks, allows users to set simple reminders. For example, you can ask ChatGPT to remind you when your passport expires in six months, and the AI assistant will follow up with a push notification on whatever platform you have tasks enabled. The feature will start rolling out to ChatGPT Plus, Team, and Pro users around the globe this week.
New ChatGPT feature lets users assign it traits like ‘chatty’ and ‘Gen Z’
OpenAI is introducing a new way for users to customize their interactions with ChatGPT. Some users found they can specify a preferred name or nickname and “traits” they’d like the chatbot to have. OpenAI suggests traits like “Chatty,” “Encouraging,” and “Gen Z.” However, some users reported that the new options have disappeared, so it’s possible they went live prematurely.
December 2024
ChatGPT Search can be tricked into misleading users, new research reveals
ChatGPT Search can be fooled into generating completely misleading summaries, The Guardian has found. They found ChatGPT could be prompted to ignore negative reviews and generate “entirely positive” summaries by inserting hidden text into websites it created and that ChatGPT Search could also be made to spit out malicious code using this method.
Microsoft and OpenAI reportedly have a finance-centric definition of AGI
Microsoft and OpenAI have a very specific, internal definition of AGI based on the startup’s profits, according to a new report from The Information. The two companies reportedly signed an agreement stating OpenAI has only achieved AGI when it develops AI systems that can generate at least $100 billion in profit, which is far from the rigorous technical and philosophical definition of AGI many would expect.
OpenAI trained o1 and o3 to ‘think’ about its safety policy
OpenAI released new research outlining the company’s approach to ensure AI reasoning models stay aligned with the values of their human developers. The startup used “deliberative alignment” to make o1 and o3 “think” about OpenAI’s safety policy. According to OpenAI’s research, the method decreased the rate at which o1 answered “unsafe” questions while improving its ability to answer benign ones.
OpenAI announces new o3 reasoning models
OpenAI CEO Sam Altman announced the successors to its o1 reasoning model family: o3 and o3-mini. The models are not widely available yet, but safety researchers can sign up for a preview. The reveal marks the end of the “12 Days of OpenAI” event, which saw announcements for real-time vision capabilities, ChatGPT Search, and even a Santa voice for ChatGPT.
OpenAI brings ChatGPT to your landline
In an effort to make ChatGPT accessible to as many people as possible, OpenAI announced a 1-800 number to call the chatbot — even from a landline or a flip phone. Users can call 1-800-CHATGPT, and ChatGPT will respond to your queries in an experience that is more or less identical to Advanced Voice Mode — minus the multimodality.
OpenAI is offering 15 minutes of free calling for U.S. users. The company notes that standard carrier fees may apply.
OpenAI brings its ChatGPT Search to more users
OpenAI is bringing ChatGPT Search to free, logged in users. Search gives ChatGPT the ability to access real-time information on the web to better answer your queries, but was only available for paid users when it launched in October. Not only is Search available now for free users, but it’s also been integrated into Advanced Voice Mode.
OpenAI blames massive ChatGPT outage on a ‘new telemetry service’
OpenAI is blaming one of the longest outages in its history on a “new telemetry service” gone awry. OpenAI wrote in a postmortem that the outage wasn’t caused by a security incident or recent product launch, but by a telemetry service it deployed to collect Kubernetes metrics.
You can make ChatGPT sound like Santa for a limited time
OpenAI announced that ChatGPT users could access a new “Santa Mode” voice during December. The feature allows users to speak with ChatGPT’s Advanced Voice Mode, but with a Christmas twist. The voice sounds, well, “merry and bright,” as OpenAI described it. Think boomy, jolly — more or less like every Santa you’ve ever heard.
OpenAI adds vision to Advanced Voice Mode
OpenAI released the real-time video capabilities for ChatGPT that it demoed nearly seven months ago. ChatGPT Plus, Team, and Pro subscribers can use the app to point their phones at objects and have ChatGPT respond in near-real-time. The feature can also understand what’s on a device’s screen through screen sharing.
There’s more to come from OpenAI through December 23. Tune in to our live blog to stay updated.
ChatGPT and Sora hit with a major outage
ChatGPT and Sora both experienced a major outage Wednesday. Though users suspected the outage was due to the rollout of ChatGPT in Apple Intelligence, OpenAI developer community lead Edwin Arbus denied it in a post on X, saying the “outage was unrelated to 12 Days of OpenAI or Apple Intelligence. We made a config change that caused many servers to become unavailable.”
starting tomorrow at 10 am pacific, we are doing 12 days of openai.
