ralph-v2-qwen3-8b-binary-p2A2-step500

A 1-bit (Q1_0 GGUF, 1.0 code bits / 1.125 container bits per weight) Qwen3-8B-architecture model, the SN40 (Ralph v2) binary-tier crown from round 7.

Method (brief)

Bonsai-8B's 1-bit signs are kept bit-exact; only the 128-element group scales and the RMSNorm weights were re-fitted by distillation from Qwen3-8B's own generated continuations (KL(parent‖student) on parent-step tokens, with extra weight on the first tokens of each step and an unlikelihood penalty on chat-template leak tokens), then exported losslessly to Q1_0. Selection used a 720-item private pool scored under three observers. Contains no auto_map, no code, and no dataset text.
