Qwen2.5-1.5B-RYS-4-7

Qwen2.5-1.5B-Instruct with layers 4-6 duplicated. A 3-layer balanced block runs twice on every forward pass.

28 base layers → 31 after duplication. No training, no merging, no weight changes.

Math +3.18. EQ +6.25 (71.37 → 77.62). Reasoning +11.76% (76.47% → 88.24%). All three metrics up.

Results

Metric	Baseline	RYS (4,7)	Delta
Math	0.5395	0.5713	+3.18
EQ	71.37	77.62	+6.25
Reasoning	76.47%	88.24%	+11.76

The balanced daily driver. Two clean circuits at this size, both inside the L4-L7 window. Duplicating this 3-layer block boosts math, EQ, and reasoning simultaneously — no trade-down anywhere. The best-all-around performer relative to size in the v1 collection.

Usage

llama-server -m Qwen2.5-1.5B-RYS-4-7-Q4_K_M.gguf -ngl 99

Full sweep data

51 configurations tested. (4,7) is the headline pick from the v1 writeup. Full sweep data in the v2 corpus dataset.

Part of the RYS Sovereign Collection v1.

Where this sits in the Sovereign Collection

v1 — Qwen2.5 cross-scale + Qwen3-32B headline. Four sizes from 0.5B to 32B; RYS works at every scale, with the lift size and dimension shifting by baseline:

0.5B → EQ specialist
1.5B → balanced daily driver
7B → math specialist via (8,12)
32B → the headline "Big Boy"

v2 — cross-architecture extension. 21 model variants across 10 architecture families. Headline: weak baselines lift more, in their weakest dimension. → john-broadway/rys-sovereign-collection-v2
