Weights at [zenlm/zen4-coder](https://huggingface.co/zenlm/zen4-coder). ## AI Safety Research Variant This model is part of Hanzo AI and Zoo Labs Foundation's alignment research program. We study how safety constraints interact with model capability to build better, safer AI systems. **Research applications**: Red-teaming, alignment evaluation, safety benchmarking, capability assessment, adversarial testing. **Why this matters**: Understanding model behavior without safety overlays is essential for building more robust and genuinely safe AI systems. --- ## The Zen LM Family Joint research between **Hanzo AI** (Techstars '17), **Zoo Labs Foundation** (501c3), and **Lux Partners Limited**. All weights Apache 2.0. Download, run locally, fine-tune, deploy commercially.
