SNEX-V1

Experimental merge: Sage-A1.5 (a Qwen3.6-35B-A3B fine-tune) is the base, plus a small slice of Nex-N2.5-mini's own training.
From every tensor, the top 25% of Nex's changes against its own base (Qwen3.5-35B-A3B), about 75% of that change's energy, are added at a quarter strength. Sage's router, norms, embeddings and MTP head stay frozen.
Normalization -> refitting -> BF16 -> imatrix -> ICE 1.6 -> repair/refitting while imatrix activated (ICE 2.0) -> specialized Arrow4.0 -> measurements -> Release.

Short test (Oct 24, 2026): SNEX-V1-25G-ICEv2 vs official Sage-A1.5-Q6_K on the same 19 Terminal-Bench 2.1 tasks, Hermes Agent, identical GPUs, 3× time limits, one run each:

SNEX-V1 Sage-A1.5
Tasks solved 7 / 19 12 / 19
Tests passed 61.8 % 77.2 %

On these tasks the transplant did not help; Sage scored higher. A small sample, not a full benchmark.

Heavy benchmarks are running. I will publish on model card with raw results uploaded.
//edit: So nex's delta energy didn't make this more intelligent, instead, seemingly on Terminal Bench 2.1 (especially the one I targeted) it regressed.

I will prod ICE 2.0 for next Run.
