Thinking Machines proposes staged, evidence-based release path for open-weight models

Thinking Machines argues that safe open-weight releases depend on both model safety testing and readiness of the surrounding ecosystem, and that release should proceed in iterative stages.

For its Inkling and Inkling-Small models, internal evaluations, four external red-teaming groups, and adversarial fine-tuning tests led the company to conclude that releasing the weights was not likely to add material risk beyond existing open-weight models.
