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, grab a coffee, and come back to a well-researched solution in 10–30 minutes. Trained end-to-end with reinforcement learning in a tool-enabled environment, deep-research is built to seek truth and understand the universe. A key milestone is its performance on humanity’s "last exam," demonstrating the true power of an end-to-end trained agent. 2025 is the year of agents. Looking forward to what’s ahead!

RT @patrickc: Deep Research has written 6 reports so far today. It is indeed excellent. Congrats to the folks behind it.

All I see is @GaryMarcus saying “Deep Research is genuinely useful” 🙂
Deep Research is genuinely useful - depending on your application - but crucially (as anticipated by Rebooting AI in 2019, and by @yudapearl) facts and temporal reasoning remain problematic for current neural network-based approaches that lean heavily on statistics rather than deep understanding.

congrats to the team, especially @isafulf and @EdwardSun0909, 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.
