ChatGPT developer OpenAI is working on a new artificial intelligence model in a project code-named "Strawberry", according to internal documents reviewed by people familiar with the matter and the media. Details of the project have never been reported before, and the company is currently working to demonstrate that the type of model it offers can provide advanced reasoning capabilities. The person familiar with the matter said that even within OpenAI, the working principle of "Strawberry" is a closely guarded secret. The person familiar with the matter also revealed that the internal document describes a project using the Strawberry model, with the aim of enabling the company's artificial intelligence to not only generate answers to queries, but also plan ahead enough to autonomously and reliably navigate the internet to perform what OpenAI calls "deep research".
