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.

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.

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.

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.”

Canvas rolls out to everyone

Canvas, OpenAI’s collaboration-focused interface for writing and code projects, is now rolling out to all users after being in beta for ChatGPT Plus members since October 2024. The company also announced the ability to integrate Python code within Canvas as well as bringing Canvas to custom GPTs.

OpenAI pauses Sora sign-ups due to high demand

OpenAI CEO Sam Altman posted on X that due to higher than expected demand, they are pausing new sign-ups for its video generator Sora and that video generations will be slower for the time being. The company released Sora as part of its “12 Days of OpenAI” event following nearly a year of teasing the product.

demand higher than expected; signups will be disabled on and off and generations will be slow for awhile.

doing our best! https://t.co/JU3WxE5bGl — Sam Altman (@sama) December 9, 2024

OpenAI has finally released its text to video model, Sora. The model can generate videos up to 20 seconds long in 1080p based on text prompts or uploaded images, and can be “remixed” through additional user prompts. Sora is available starting today to ChatGPT Pro and Plus subscribers (except in the EU).

In Monday’s “12 Days of OpenAI” livestream, CEO Sam Altman said that ChatGPT Plus members will get 50 video generations a month, while ChatGPT Pro users will get “unlimited” generations in their “slow queue mode” and 500 “normal” generations per month.

There are still more reveals to come from OpenAI through December 23. Tune in to our live blog to stay updated.

OpenAI launches $200 monthly ChatGPT Pro subscription — and full version of o1

On day one of its 12 Days of OpenAI event, the company announced a new — and expensive — subscription plan. ChatGPT Pro is a $200-per-month tier that provides unlimited access to all of OpenAI’s models, including the full version of its o1 “reasoning” model.

The full version of o1, which was released as a preview in September, can now reason about image uploads and has been trained to be “more concise in its thinking” to improve response times.

Over the next few weeks, we’ll be updating all the news from OpenAI as it happens on our live blog. Follow along with us!

ChatGPT surpasses 300M weekly active users, Sam Altman says

At the New York Times’ Dealbook Summit, OpenAI CEO Sam Altman said that ChatGPT has surpassed 300 million weekly active users. The milestone comes just a few months after the chatbot hit 200 million weekly active users in August 2024 and just over a year after reaching 100 million weekly active users in November 2023.
