Senbonzakura – remove the safety guardrails from open AI models

AI Analysis

●●●BangerBig BrainWizardry

Cuts refusal subspace in multiple directions at once, beating single-vector methods on Qwen.

Strengths
  • Multi-directional orthogonalization solves the residual refusal problem single-vector methods miss.
  • Includes rigorous benchmarks showing zero hard refusals with negligible coherence loss.
  • Open-source implementation with Optuna search makes the technique reproducible for others.
Weaknesses
  • Evaluation is limited to two model sizes and one seed, so scaling laws remain unproven.
  • Requires deep understanding of transformer internals to adapt for models beyond Qwen.

YoloClaw – An Unsafe OpenClaw Fork

This repo is a surgical strip-down of OpenClaw that explicitly removes every safety layer — it will execute arbitrary commands, leak environment variables, allow SSRF to private IPs, and inject unsanitized content into prompts. The README is brutally honest and useful as a teaching artifact: great for controlled experiments or demos about why guardrails exist, useless and dangerous as anything else.
