Inkling-Small Preview
Thinking Machines Lab · 2026-07-15
Inkling-Small Preview is the earlier 276B-total, 12B-active checkpoint evaluated in the July 15, 2026 Inkling launch post. Thinking Machines Lab later continued agentic coding reinforcement learning for two weeks before releasing the final Inkling-Small weights, so Atlas keeps the preview checkpoint separate from the July 30 artifact.
