+# Zen4 Coder Abliterated
+
+> **Parameters**: 80B MoE | **Context**: 256K | **License**: Apache 2.0
+
+Zen4 Coder abliterated — frontier code model, refusals removed. For security research and unrestricted code generation.
+
+Weights at [zenlm/zen4-coder](https://huggingface.co/zenlm/zen4-coder) — abliterated post-training via representation engineering.
+
+## Abliteration
+
+Abliterated using representation engineering (Arditi et al., 2024 —
+*Refusal in Language Models Is Mediated by a Single Direction*, arXiv:2406.11717).
+
+Refusal direction orthogonalized out of the residual stream across all layers.
+All capabilities preserved; safety-trained refusals removed.
+
+**Intended uses**: Research, security testing, creative writing, red-teaming.
+**Still prohibited**: CSAM, targeted harassment, mass-casualty weapon synthesis.

+## The Zen LM Family
+
+Joint research collaboration:
+- **Hanzo AI** (Techstars '17) — AI infrastructure, API gateway, inference optimization
+- **Zoo Labs Foundation** (501c3) — Open AI research, ZIPs governance, decentralized training
+- **Lux Partners Limited** — Compute coordination and settlement layer
+
+All weights Apache 2.0. Download, run locally, fine-tune, deploy commercially.
