Strawberry is rumored to be based upon the QStar AI advance. QStar was a reasoning advance that supposedly triggered the power struggle inside OpenAI and temporary firing of CEO Sam Altman.

Strawberry supposedly enables AI to perform long-horizon tasks (LHT), which require a model to plan ahead and execute a series of actions over an extended period of time. This technology aims to improve AI's ability to understand and interact with the world, allowing it to autonomously search the internet and conduct deep research. By improving how AI models think and plan, OpenAI hopes to unlock new levels of intelligence and bring AI closer to human-level intelligence or beyond.

ChatGPT maker OpenAI is working on a novel approach to its artificial intelligence models in a project code-named "Strawberry," according to a person familiar with the matter and internal documentation reviewed by Reuters. The project, details of which have not been previously reported, comes as the Microsoft-backed startup races to show that the types of models it offers are capable of delivering advanced reasoning capabilities.

How Strawberry works is a tightly kept secret even within OpenAI, the person said. The document describes a project that uses Strawberry models with the aim of enabling the company's AI to not just generate answers to queries but to plan ahead enough to navigate the internet autonomously and reliably to perform what OpenAI terms "deep research," according to the source.

Ilya Sutskever was the Chief Scientist at OpenAI, but he has left and formed his own company, Safe SuperIntelligence. Ilya knows about QStar and Strawberry. It would tough to keep this breakthrough secret. Others in the community are pursuing reasoning breakthroughs.
