Introducing OpenAI o3 and o4-mini—our smartest and most capable models to date.
For the first time, our reasoning models can agentically use and combine every tool within ChatGPT, including web search, Python, image analysis, file interpretation, and image generation.

@OpenAI
OpenAI o3 is a powerful model across multiple domains, setting a new standard for coding, math, science, and visual reasoning tasks.
o4-mini is a remarkably smart model for its speed and cost-efficiency. This allows it to support significantly higher usage limits than o3, making it a strong high-volume, high-throughput option for everyone with questions that benefit from reasoning.

@OpenAI
OpenAI o3 and o4-mini are our first models to integrate uploaded images directly into their chain of thought.
That means they don’t just see an image—they think with it.

@OpenAI
ChatGPT Plus, Pro, and Team users will see o3, o4-mini, and o4-mini-high in the model selector starting today, replacing o1, o3-mini, and o3-mini-high.
ChatGPT Enterprise and Edu users will gain access in one week. Rate limits across all plans remain unchanged from the prior set of models.
We expect to release o3-pro in a few weeks with full tool support. For now, Pro users can still access o1-pro in the model picker under ‘more models.’

@OpenAI
Both OpenAI o3 and o4-mini are also available to developers today via the Chat Completions API and Responses API.
The Responses API supports reasoning summaries, the ability to preserve reasoning tokens around function calls for better performance, and will soon support built-in tools like web search, file search, and code interpreter within the model’s reasoning.

I am impressed with the o3 model released today by @OpenAI
First model to one shot solve this!
o4-mini-high managed to solve in a few tries, same as other models
Congrats @sama and the team
Can you solve it?

First “agentic”. Now “agentically”

If you can’t use the word without feeling embarrassed in front of your parents, don’t use the word

Still seems to have problem using image gen. Refusing requests to change outfits for visualizing people in products, etc.

Just published today's edition of my newsletter.

OpenAI launched of o3 full model and o4-mini and a variant of o4-mini called “o4-mini-high” that spends more time crafting answers to improve its reliability.

OpenAI o3 and o4-mini models are live on Langbase.

First visual reasoning models

o3: Flagship reasoning, knowledge up-to June 2024, cheaper than o1

o4-mini: Fast, better reasoning than o3-mini at same cost

The models keep getting smarter

The next question is: who owns them?
Open access is cool.
Open ownership is the future.

"wtf I thought 4o-mini was supposed to be super smart, but it didn't get my question at all?"
"no no dude that's their least capable model. o4-mini is their most capable coding model"

This is my favorite AI tool for reviewing reports.
Just upload a report, ask for a summary, and get one in seconds.
It's like ChatGPT, but built for documents.
Try it for free.
