John Schulman, a prominent artificial intelligence researcher who co-founded OpenAI, has left rival firm Anthropic, a job he held since the summer.

“We’re introducing an updated [chain of thought] for o3-mini designed to make it easier for people to understand how the model thinks,” an OpenAI spokesperson told TechCruch via email. “With this update, you will be able to follow the model’s reasoning, giving you more clarity and confidence in its responses.”

OpenAI's o3-mini model claims similar performance to o1 but at a fraction of the cost, so I put it to the test to find out

Researchers at Stanford and the University of Washington have developed a model that performs comparably to OpenAI o1 and DeepSeek R1 models in math and coding — for less than $50 of cloud compute credits.

A team of researchers at Stanford and the University of Washington have developed an AI reasoning model, s1, for less than $50. This is a massive achievement, given the notion that significant financial resources are essential for developing AI reasoning models.
