Thinking Machines Lab Launches Inkling 2 Small With Weights Closed

A July staged-access framework presented Inkling and Inkling-Small as open-weight models and tied broader availability to safety evidence and ecosystem readiness. “On a safe path to openness, each stage should widen access only when the evidence supports it,” Thinking Machines wrote. The launch begins with hosted model use, while the full-weight release remains a later step with no specific calendar date. Inkling 2 Small has 594 billion total parameters, with 17 billion active per token. It uses a sparse mixture-of-experts architecture that routes each token to eight of 384 experts.
