Thinking Machines Lab releases Inkling 2 Small 594B MoE model

Thinking Machines Lab (led by former OpenAI CTO Mira Murati) released Inkling 2 Small, a 594-billion-parameter Mixture-of-Experts model with 17 billion active parameters that supports image inputs. It scored 31 on the Artificial Analysis Intelligence Index and is available on the Tinker platform with closed weights; Apache 2.0 weights are planned after safety testing. The release advances efficient, high-capability open-weight candidates outside the largest US and Chinese labs.
