I have yet to find a well-defined task that cannot be optimized by these models. Eval improvement like ARC AGI showcase this dynamic

Reasoning has begun to deliver us better models like o1, o3, o3-mini, but the genuine unlock will be agents. Reasoning gives us better planning, tool-use, error recovery and I’m thrilled for this year. 2025 is the year of agents. Congrats team!!

o3-mini's intelligence x speed combo is incredible, idk what to say other than just try it and see for yourself. This took 8 seconds, how long would it take you?

All free ChatGPT users now have reasoning models with o3-mini. The cost-intelligence frontier is shifting fast (o3-mini outperforms even o1 on many STEM evals!)

We released o3-mini today! Everyone can use it for free. It reasons hard, reasons fast, searches the web, and most importantly, knows research. Ask the model hard questions and brainstorm with it!

We already have a quick pace of improvement on challenging benchmarks (4o at 3%, o1 at 9%, deep research at 27% in humanity's last exam), but expect further acceleration as AI becomes an even larger contributor to future AI development

Very excited to finally share OpenAI's "deep research" model, which achieves twice the score of o3-mini on Humanity's Last Exam, and can even perform some tasks that would take PhD experts 10+ hours to do! A few thoughts on the implications: Deep research can be seen as a new

Excited to finally share what I’ve been working on since joining OpenAI last June! The goal of deep-research is to enable reasoning models with tools to tackle long-horizon tasks in the real world and discover new knowledge. It’s a highly autonomous agent—hand it a hard problem,

Very excited to finally launch deep research!

congrats to the team, especially Isa Fulford and Zhiqing Sun, for building an incredible product. my very approximate vibe is that it can do a single-digit percentage of all economically valuable tasks in the world, which is a wild milestone.

Gary Marcus: AGI achieved

We're expanding deep research to more users today! The initial feedback from our Pro users has been incredible (thanks!) and we think deep research is an excellent demonstration of how reasoning models unlock reliable agents. Next, we will continue to expand the reach of this

We’re expanding advanced voice access to free users!

Vibes are key to get right especially in subjective areas of AI products and we’re always talking about this. Love to see the vibes level-up here that goes beyond a basic try-on for new outfits

This will be an excellent model -- tune in!

Attracting and keeping world-class talent is the only way the US will succeed in AI and other advanced technologies

As AI capability continues to improve and becomes ubiquitous, a differentiator of products will come from effectively making contact with their industry and solving their specific problems. Congrats Mirror Mirror for doing this and nailing fashion aesthetics in image generation!

In Raj's defense, the prior success rate for chatbots before ChatGPT was ~0, so this isn't the worst take I've ever read
