Inkling is Thinking Machines Lab’s first big AI model launch, and comes a little more than a year after the start-up was founded.

Mira Murati’s Thinking Machines Lab has unveiled the first of its family of multimodal open-source models called Inkling. The model was the first from the start-up to be trained on Nvidia GB300 NVL72 systems, following a partnership agreement between the two companies earlier this year.

Inkling does not promise to be the strongest open or closed model available, but rather markets itself as one made to be customised. It has 975bn total parameters, with 41bn active, and supports a context window of up to 1m tokens.

“Inkling is designed to be broad. We trained it across agentic, reasoning, coding, instruction-following, factuality, vision, and audio tasks, rather than narrowly optimising for one domain,” Thinking Machines Lab said in a blogpost announcing the new model on Wednesday (15 July).
