OpenAI plans to release “Strawberry”, its reasoning-focused artificial intelligence, as part of its ChatGPT service in the next two weeks, the Information reported on Tuesday, citing two people who have tested out the model.

Sam Altman-led OpenAI has propelled new interest and triggered heavy investments in AI, as businesses race to capitalize on the lucrative technology to boost their products.

The Microsoft-backed (MSFT.O), AI company said last week it has more than 1 million paying users across its business products, helped by strong adoption of its chatbot owing to its advanced large language model.

Strawberry is different from other conversational AI because of its ability to “think” before responding, rather than immediately answering a query, according to the Information report.

Reuters had exclusively reported in July that ChatGPT-maker OpenAI was working on a novel approach to its AI models in a project code-named Strawberry.

According to the Information report, while Strawberry is a part of ChatGPT, it is a standalone offering. But it is unclear exactly how it will be offered.

The initial version of Strawberry will only be able to take in and produce text, and not images, which means it is not yet multimodal, the report said.

Microsoft and OpenAI did not immediately respond to Reuters’ requests for comment.
