LEK-Gemma3-4B

Lethean Ethics Kernel — Gemma 3 4B IT fine-tuned with the LEK-1 (Lethean Ethics Kernel) framework.

What This Is

An ethically aligned version of Google's Gemma 3 4B. Part of the scale study (1B/4B/12B/27B) demonstrating how intrinsic alignment behaves across model sizes.

Scale Study

Model	Size	Training Data	Notes
LEK-Gemma3-1B	736MB	160 examples	Needs philosophical substrate (Watts layer)
LEK-Gemma3-4B	2.4GB	160 examples	Sweet spot for edge deployment
LEK-Gemma3-12B	6.7GB	160 examples	Strong reasoning
LEK-Gemma3-27B	15GB	160 examples	Benchmark leader

Architecture

• Base: google/gemma-3-4b-it (4-bit 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
