The AI That Can Re-Write Its Own Brain: Why Inkling is the New Frontier for Open Weights

Thinking Machines Lab released Inkling on July 15, 2026, an open-weights AI model that can rewrite its own code and update its own internal settings without human help. Built on 975 billion parameters but activating only 41 billion at a time, Inkling completed a full self-modification task in 27 minutes. Developers can also adjust its "thinking effort" on demand, matching top competitors while using far fewer computing resources.
