Gemma-2-2B-RYS-19-23

Gemma-2-2B-it with layers 19-22 duplicated. A late-stack reasoning circuit runs twice on every forward pass.

26 base layers → 30 after duplication. No training, no merging, no weight changes.

Reasoning 58.82% → 64.70% (+5.88). EQ 91.72 → 93.87 (+2.15). Math 0.522 → 0.5027 (−1.93). Peak reasoning Δ across the full 36-config sweep is +17.65%; (19,23) is the best-combined pick.

Results

Metric	Baseline	RYS (19,23)	Delta
Math	0.522	0.5027	−1.93
EQ	91.72	93.87	+2.15
Reasoning	58.82%	64.70%	+5.88

The smaller-Gemma. Within-family control for the larger Gemma-2-9B sibling. The two share baseline reasoning (58.82%) but the 9B finds richer duplicate-circuit candidates (peak +23.53% with 17 boosters) than this 2B (peak +17.65% with 4 boosters). Depth-room scaling: at matched baseline, more layers means more candidate blocks where duplication moves the reasoning probe.

Pick this when you want a tiny Gemma with reasoning lifted modestly and EQ slightly improved.

Usage

llama-server -m Gemma-2-2B-RYS-19-23-Q4_K_M.gguf -ngl 99

Full sweep data

36 configurations tested. (19,23) block-4 is the best-combined pick. Full per-config sweep + cross-architecture analysis: v2 dataset.

Part of the RYS Sovereign Collection v2.

Where this sits in the Sovereign Collection

v1 — Qwen2.5 cross-scale + Qwen3-32B headline crossover. 5 model repos.

v2 — cross-architecture corpus. 21 model variants across 10 architecture families. Inverse correlation (r = −0.726): weak baselines lift more, in their weakest dimension. 13 deployable RYS-applied weight repos covering every non-zero-lift variant.

Within-family sibling: john-broadway/Gemma-2-9B-RYS-14-18-GGUF — the bigger Gemma with the same baseline and more lift, plus the highest baseline EQ in the corpus.
