Open model Inkling 2 Small repairs broken networks from raw weights in ~40 tokens

Thinky Machines demonstrated "weight-space programming": its open model Inkling 2 Small, post-trained on Tinker, can repair broken neural networks directly from their raw weights in about 40 tokens, with no reasoning steps.

In comparisons, the untrained model needed a full generation to fix one break; after post-training it both answers 207 correctly and repairs 176 broken networks. The author frames this as an early step toward having models program directly in weight space.
