Benchmark: can an LLM make a language model better at math by editing its weights directly? (Qwen3.5-0.8B, MATH-500/GSM8K, via OpenRouter)
Agent skill for weight-space programming: edit LLM weights
Give AI agents tools to inspect, edit, and test model weights: an MCP harness and Python toolkit for weight-editing experiments.
Direct weight surgery for LLMs — edit weights, not gradients. Extract the arrow, leave the body intact.
Open-source weight space editing for small language models. Direct tensor edits, measured hill climbs and a Hugging Face workbench.
Give it your documents and a goal. A coding agent builds your own small AI, tests it honestly, and fixes its bad habits by editing weights.
Fixing small language model defects (reasoning loops…) by having an LLM (Claude Opus in Claude Code) edit their weights directly, without training — measured against the original by slm-quality-bench
Closed-form weight edits for Gemma 4 that a coding agent can drive: find where the model makes a choice, build low-rank edits without gradients, and judge each against size-matched random edits (target, keep, side effects). MLX and PyTorch backends; exports LoRA adapters.
Weight-space programming on a 27B production model: sandboxed kernel, metered forward passes, sealed held-out eval, every transcript
Can frontier models fix a coding agent by editing its weights? Code, protocols, records, frozen gate reports and agent configs of the Gemma 4 E4B weight-edit study, with the full paper (PDF) and both Kaggle writeups.
Can an LLM repair sycophancy by editing weights directly? A gradient-free edit of 0.23 % of Qwen2.5-0.5B cuts wrong-hint flips from 76.8 % to 32.3 % on a blind test split, but correct hints also help less on unknown questions.
The map of modifying model weights directly: knowledge editing, steering & abliteration, task arithmetic, unlearning, and the weight-space programming wave. 权重编辑全景 · 中英双语 · Daily radar 🤖
