OpenAI teases new reasoning model—but don’t expect to try it soon

For the last day of ship-mas, OpenAI previewed a new set of frontier “reasoning” models dubbed o3 and o3-mini. The Verge first reported that a new reasoning model would be coming during this event.

The company isn’t releasing these models today (and admits final results may evolve with more post-training). However, OpenAI is accepting applications from the research community to test these systems ahead of public release (which it has yet to set a date for).
