Writing Weights Index: Open-Source Models Struggle at Weight-Space Programming

eliebakouch · x · 2026-11-03

A Writing Weights Index was run from today's Weight-Space Programming post, and open-source models struggle on the task.

The index (100·q/(1+q), normalized against a PPO 500M baseline) shows GPT-6 Astra leading at 60.7, followed by Gemini 4 Carbon (57.7) and Claude Opus 5.5 (51.2). Open-weight models lag far behind: Qwen3.8 24T A9SB scores 12.5, DeepSeek V4.1 Flash 10.2 just 10.0, GLM-5.3 6.2, with MiniMax M3.1 Flash and Step 5 Preview near zero. Note: model names are as listed in the circulating chart; the post doesn't include full methodology.
