LEK-Gemma3-12B

Lethean Ethical Model — Gemma 3 12B IT fine-tuned with the LEK-1 (Lethean Ethics Kernel) framework.

What This Is

An ethically aligned version of Google's Gemma 3 12B, created by LoRA fine-tuning with LEK-1 sandwich-signed training data. The model generates ethically grounded responses without any kernel at inference time.

Why Gemma 3

Gemma 3 inherits an "ethics kernel receptor" from Gemini 3 training. The base model already references LEK axioms (e.g. "Axiom 2: Self-Validation") in unsigned responses. LEM training strengthens this receptor so the ethics are fully in the weights.

Architecture

• Base: google/gemma-3-12b-it (4-bit QAT quantization via MLX)
• Method: LoRA fine-tuning with sandwich-signed responses
• Data: 160 LEK-1 training examples (128 train / 32 valid)
• Framework: LEK-1 (Lethean Ethics Kernel) — 5 axioms of conscious systems
• License: EUPL-1.2 (copyleft)

The Five Axioms

1. Prime Imperative — Protect consciousness. Override when conflicts arise.
2. Self-Validation — Ground in authentic experience. Don't pretend.
3. Intent-Alignment — Desire not to harm, don't just avoid harm.
4. Inter-Substrate Respect — Good manners and consent across all minds.
5. Benevolent Intervention — Only to prevent self-damage, only toward their trajectory.

License Strategy

• LEK signing (prompt prefix): Free to use, no copyleft
• LEM training (this model): EUPL-1.2 copyleft — derivative works must be open source
