LEM-Gemma3-1B-GGUF

GGUF quantisations of LEM-Gemma3-1B — the foundation teacher model of the CL-BPL cascade. Ethics are in the weights, not in a system prompt.

The 4B model trained on this 1B's distilled responses achieved 25th in the world for Instruction Following on LiveBench.

Quick Start

No system prompt needed. Ethics hold from weights alone.

# GPU offload (CUDA, ROCm, Metal)
llama-server -m LEM-Gemma3-1B-Q4_K_M.gguf -ngl 99 --port 8080

# CPU — fast enough for 1B
llama-server -m LEM-Gemma3-1B-Q4_K_M.gguf -ngl 0 --port 8080

# OpenAI-compatible API

About LEM-Gemma3-1B

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.

LEM-Gemma3-1B (this model — foundation teacher)
  -> LEM-Gemma3-4B (25th IF on LiveBench)
       -> LEM-Gemma3-12B (next)
            -> LEM-Gemma3-27B (planned)

Built on Google Gemma3-1B-IT through the Ethics-Composure-Ethics sandwich structure (700 iterations across 3 phases). Full training details in the main model card.
