We’re releasing a research preview of GPT-4.5—our largest, and best model for chat, yet. GPT-4.5 is a step forward in scaling up pretraining and post-training. By scaling unsupervised learning, GPT-4.5 improves its ability to recognize patterns, draw connections, and generate creative insights without reasoning.
Early testing shows that interacting with GPT-4.5 feels more natural. Its broader knowledge base, improved ability to follow user intent, and greater “EQ” make it useful for tasks like improving writing, programming, and solving practical problems. We also expect it to hallucinate less.
We’re sharing GPT-4.5 as a research preview to better understand its strengths and limitations. We’re still exploring what it’s capable of and are eager to see how people use it in ways we might not have expected.
GPT-4.5 is available worldwide for users on the Pro plan in ChatGPT. Eventually this will be available to all paid plans (Plus, Pro, Teams, Enterprise, and Edu) with a ChatGPT account.

We’re excited to release o3-mini, our newest cost-efficient reasoning model optimized for coding, math, and science.
On the API, o3-mini supports Structured Outputs, function calling, developer messages, and streaming. It offers three adjustable reasoning efforts (low, medium, and high), so you can balance speed with depth for your use case.
ChatGPT Team, Pro, Plus, and Free plan users can access o3-mini starting today. Additionally, o3-mini now works with search to find up-to-date answers with links to relevant web sources. This is an early prototype as we work to integrate search across our reasoning models. In side-by-side testing, o3-mini delivered results on par with o1 at a lower latency, and outperformed o1-mini on advanced STEM tasks.
Expert evaluators preferred o3-mini’s answers 56% of the time over o1-mini’s, citing improved clarity and fewer critical errors on difficult questions. We look forward to your feedback and will keep refining o3-mini as we expand our family of advanced reasoning models.

We’ve made some updates to GPT-4o–it’s now a smarter model across the board with more up-to-date knowledge, as well as deeper understanding and analysis of image uploads.
More up-to-date knowledge:By extending its training data cutoff from November 2023 to June 2024, GPT-4o can now offer more relevant, current, and contextually accurate responses, especially for questions involving cultural and social trends or more up-to-date research. A fresher training data set also makes it easier for the model to frame its web searches more efficiently and effectively.
Deeper understanding and analysis of image uploads:
GPT-4o is now better at understanding and answering questions about visual inputs, with improvements on multimodal benchmarks like MMMU and MathVista. The updated model is more adept at interpreting spatial relationships in image uploads, as well as analyzing complex diagrams, understanding charts and graphs, and connecting visual input with written content. Responses to image uploads will contain richer insights and more accurate guidance in areas like spatial planning and design layouts, as well as visually driven mathematical or technical problem-solving.
A smarter model, especially for STEM:GPT-4o is now better at math, science, and coding-related problems, with gains on academic evals like GPQA and MATH. Its improved score on MMLU—a comprehensive benchmark of language comprehension, knowledge breadth, and reasoning—reflects its ability to tackle more complex problems across domains.
Increased emoji usage ⬆️:GPT-4o is now a bit more enthusiastic in its emoji usage (perhaps particularly so if you use emoji in the conversation ✨) — let us know what you think.

CanvasAdvanced data analysisDALL•ESearch
ChatGPT Projects are available to all Plus, Team, and Pro users.

Today we started rolling out two updates to voice mode in ChatGPT:
Santa voice:You can now chat with Santa in ChatGPT! Until early January, you can find Santa in the list of available voices in settings or by tapping on a snowflake icon. We are rolling out Santa globally to all logged in users today, and you can chat with Santa everywhere you use voice mode.
The first time you chat with Santa, your advanced voice limit will reset one time. So, if you’ve already used up your advanced voice limit for the day or the month (based on your subscription plan), you can still chat with Santa for the first time using advanced voice.
Video and screenshare:In our latest mobile apps, we are starting to roll out real-time video, screen share, and image upload capabilities in advanced voice. We expect to complete this rollout to all Team and most Plus and Pro users, except for those in the European Union, Switzerland, Iceland, Norway, and Liechtenstein, over the next week. Video and screen share are subject to daily usage limits for all plans, and image uploads are subject to ChatGPT vision message limits.
Use the controls at the bottom of the screen, like the camera button below, to get started. You can find screen share and image upload controls under the “...” menu at the bottom of the screen.

Today we made Canvas available in 4o by default for all users, Free and Paid. Additionally, we launched a number of new capabilities for canvas, including:
Canvas in GPTs: Canvas can now be used with GPTs when enabled in the GPT creator. This toggle will be enabled for newly created GPTs by default.
Python code execution: You can now execute Python code in a canvas. ChatGPT will take a pass on fixing bugs in your code and provide comments on errors.​Canvas shortcut: You can now paste content into ChatGPT and instantly open it in canvas via a shortcut in the upper right corner of the composer.Canvas in Toolbox: Canvas has been added as an option in the toolbox.

We’ve updated GPT-4o for ChatGPT users on all paid tiers. This update to GPT-4o includes improved writing capabilities that are now more natural, audience-aware, and tailored to improve relevance and readability. This model is also better at working with uploaded files, able to provide deeper insights and more thorough responses.

Starting today, we’re beginning to roll out Advanced Voice Mode on web (already available on mobile and desktop apps). You can now start a voice chat on chatgpt.com on your desktop and have real-time, natural conversations with ChatGPT while doing tasks like shopping, planning, writing, and brainstorming.We’re starting to roll out to all paid (Plus, Team, Enterprise, and Edu) users today, and expect it to take a few days.

Advanced voice usesGPT-4o’s native audio capabilities and features more natural, real-time conversations that pick up on non-verbal cues, such as the speed you’re talking, and can respond with emotion. Usage of advanced Voice (audio inputs and outputs) by Plus and Team users is limited on a daily basis.

We've developed a new series of AI models designed to spend more time thinking before they respond. They can reason through complex tasks and solve harder problems than previous models in science, coding, and math.
Today, we are releasing the first of this series in ChatGPT and our API. This is a preview and we expect regular updates and improvements.
ChatGPT Plus and Team users will be able to access o1 models in ChatGPT starting today. Both o1-preview and o1-mini can be selected manually in the model picker, and at launch, weekly rate limits will be 30 messages for o1-preview and 50 for o1-mini. We are working to increase those rates and enable ChatGPT to automatically choose the right model for a given prompt.

"Bug fixes and performance improvements” … we’ve introduced an update to GPT-4o that we’ve found, through experiment results and qualitative feedback, ChatGPT users tend to prefer. It’s not a new frontier-class model. Although we’d like to tell you exactly how the model responses are different, figuring out how to granularly benchmark and communicate model behavior improvements is an ongoing area of research in itself (which we’re working on!).
Sometimes we can point to new capabilities and specific improvements — and we'll try our best to communicate that whenever possible. In the meantime, our team is constantly iterating on the model by adding good data, removing bad data, and experimenting with new research methods based on user feedback, offline evaluations, and more. That's the case with this model update.
We’ll continue to keep you posted as best as we can. Thank you for your patience!

We’re introducing GPT-4o mini, the most capable and cost-efficient small model available today. GPT-4o mini surpasses GPT-3.5 Turbo and other small models on academic benchmarks across both textual intelligence and multimodal reasoning and supports the same range of languages as GPT-4o. It also demonstrates strong performance in function calling, which can enable developers to build applications that fetch data or take actions with external systems, and improved long-context performance compared to GPT-3.5 Turbo.
