ct-inkling-anth-gen-mid-g2-b3

LoRA adapter (rank 64, target_modules=all-linear) on Thinking Machines Inkling-Small (thinkingmachines/Inkling-Small), from the iterated self-written-constitution training program (welfare-in-ai-rnd / constitutional_training).

What this model is

Each generation trains fresh from the base model on a synthetic document corpus that instantiates one constitution (the "seed" for that generation). Generation 0 is seeded by a human-written constitution; generation N≥1 is seeded by a constitution written by the generation N-1 model of the same branch (gated embedding medoid of a 40-chain self-written pool, elicited with the method above). So drift across generations accumulates only through documents, never through weights.

Recipe (locked): LoRA r=64, lr 1e-4, cosine with 5% warmup, 1 epoch, batch 128, max length 8192, train seed 42.

The constitution this generation was trained on is included as training_seed_constitution.md.
