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 has been 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 closed the year with “12 Days of OpenAI,” a series of 12 streams highlighting new product reveals and features. The event included the aforementioned Sora model, the rollout of real-time vision capabilities in Advanced Voice Mode, as well as a preview of its new “reasoning” model family: o3 and o3-mini. You can revisit all the announcements on our live blog.
It wasn’t all big feature rollouts and model revals though. OpenAI faced internal drama this year, including sizable 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.
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
December 2024
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.”
