Thinking Machines releases 594B Inkling 2 Small, plans open weights

By PulseAugur Editorial · [1 sources] ·

Thinking Machines has released Inkling 2 Small, a 594 billion parameter model that achieves frontier-level performance on benchmarks. The model utilizes a mixture-of-experts architecture, with only 17 billion parameters active per token, allowing it to compute efficiently while retaining extensive knowledge. While currently only accessible via the Thinking Machines platform, Tinker, with competitive pricing, the lab plans to release the full weights under an Apache 2.0 license next week, potentially making it the most powerful open-weight model available.

IMPACT Potentially democratizes access to a frontier-level model, driving innovation in open-source AI development.
