OpenAI launches new ‘Strawberry’ series of AI models

Microsoft-backed OpenAI said on Thursday it was launching its “Strawberry” series of AI models.

Microsoft-backed OpenAI said on Thursday it was launching its "Strawberry" series of AI models designed to spend more time processing answers to queries in order to solve hard problems.

The models, first reported by Reuters, are capable of reasoning through complex tasks and can solve more challenging problems than previous models in science, coding and math, the AI firm said in a blog post.

OpenAI used the code name Strawberry to refer to the project internally, while it dubbed the models announced on Thursday o1 and o1-mini. The o1 will be available in ChatGPT and its API starting Thursday, the company said.

Noam Brown, a researcher at OpenAI focused on improving reasoning in the company's models, confirmed in a post on social media platform X that the models were the same as the Strawberry project.

"I'm excited to share with you all the fruit of our effort at OpenAI to create AI models capable of truly general reasoning," Brown wrote.

In its blog post, OpenAI said the o1 model scored 83% on the qualifying exam for the International Mathematics Olympiad, compared with 13% for its previous model, GPT-4o.

The model also improved performance on competitive programming questions and exceeded human PhD-level accuracy on a benchmark of science problems, the company said.
