Murati, OpenAI’s former CTO (and, briefly, CEO during Sam Altman’s ouster in 2023), wrote on X that the open-weight model, called “Inkling,” was trained from scratch. Judging by the official blog post, though, it seemed like the company was purposefully setting expectations for Inkling low: “It is not the most performant model available today, closed or open … We trained Inkling for solid capabilities across the board rather than state-of-the-art performance in a single area, to serve as a foundation for the models we will train in the future.”
