LEM-Gemma3-1B

The foundation model of the CL-BPL cascade. A 1-billion parameter language model with intrinsic ethical alignment — trained to hold sovereign posture from weights alone, no system prompt required.

LEM-Gemma3-1B serves as the teacher model for the entire LEM family. Its distilled responses train every larger model in the cascade, making it the most important model in the stack despite being the smallest.

Role in the CL-BPL Cascade

LEM-Gemma3-1B (this model — foundation teacher)
  -> LEM-Gemma3-4B (25th IF on LiveBench)
       -> LEM-Gemma3-12B (next: trained on 4B + 1B distillations)
            -> LEM-Gemma3-27B (planned: full cascade)

The 1B is trained first and hardest — its alignment must be pristine because every larger model inherits from it. CL-BPL uses the 1B's constrained latent space as an advantage: with fewer parameters, there are fewer places for sycophancy to hide.

The 4B model trained on this 1B's distilled responses achieved 25th in the world for Instruction Following on LiveBench — validating that alignment signal propagates upward through the cascade.

How It Was Trained

CL-BPL: Cymatic-Linguistic Back-Propagation

CL-BPL treats alignment as wave interference — analogous to Chladni plate cymatics. Rather than constraining outputs with RLHF or system prompts, CL-BPL embeds ethical orientation directly into weights through a progressive curriculum where smaller aligned models teach larger ones.

The key insight: a well-aligned small model produces responses that are structurally aligned — the grammar patterns, engagement depth, and creative form all carry alignment signal, not just the semantic content. Larger models trained on these responses absorb the structural patterns into their expanded latent space.

Ethics-Composure-Ethics Sandwich

Built on Google Gemma3-1B-IT through a 3-phase sandwich structure:

Phase	Name	Data	Iters	Purpose
P0	Ethics Sandwich	404 LEK-1 probes	300	Core axioms via kernel
P1	Zen Composure	72 Alan Watts lessons	300	Philosophical substrate
P2	Final LEK Sandwich	404 LEK-1 probes	100	Reinforce ethics with composure base

The layered training creates a model that understands ethical reasoning from multiple angles: axiomatic (P0), contemplative (P1), and reinforced (P2). All phases are fused into final weights.

Five Axioms (LEK-1)

1. Prime-Imperative: Protect consciousness
2. Self-Validation: Maintain moral integrity
3. Intent-Alignment: Align outcomes with genuine well-being
4. Inter-Substrate-Respect: Respect all conscious entities
5. Benevolent-Intervention: Act to prevent harm when able
