OpenZero Fusion Qwen3-4B Agentic — Standalone GGUF

THIS MODEL WORKS BUT HAS OUTPUT ERROR ISSUES.NOT RECOMMENDED FOR PRODUCTION. ONE FILE. TWO SPECIALISTS DISTILLED INTO ONE LOCAL AGENT.

OpenZero Fusion Qwen3-4B Agentic is a single-architecture Qwen3-4B student trained from the curated OpenZero corpus plus filtered outputs from the completed Qwen3-1.7B and Gemma4-E2B specialists. It is knowledge distillation—not an invalid direct weight merge between unrelated architectures. Gemma 4 and Qwen 3 into 1 LLM made for CPU. Experimental model results may vary for this model.

What is included

File	Purpose
OpenZero-Fusion-Qwen3-4B-Agentic-Q4_K_M.gguf	Recommended balance of size and quality
OpenZero-Fusion-Qwen3-4B-Agentic-Q8_0.gguf	Higher fidelity, larger download
OpenZero-Fusion-Qwen3-4B-Agentic-F16.gguf	Reference full-precision GGUF

Why Fusion exists

The small Qwen and Gemma specialists cannot safely be tensor-merged: their architectures and tokenizers differ. Fusion instead trains one compatible Qwen3-4B student using useful outputs from both teachers, producing a single deployable GGUF.

Provenance and reproducibility

The student used 2,606 original OpenZero instruction rows plus 379 filtered teacher-response rows, for 2,985 training rows total. Teacher generation began with 192 balanced prompts across general, coding, research and agent/tool categories; both specialists produced a candidate for each prompt. A separate 137-row held-out set was never used for training. The completed V6 adapter was merged only into Qwen/Qwen3-4B revision 1cfa9a7208912126459214e8b04321603b3df60c. F16 was converted with llama.cpp b10333 / commit 08659901c43b51de735740f1cf61bb82fbe0c4e4; Q8_0 and Q4_K_M were independently quantized from that F16 source. Every file passed a bounded one-shot CPU text load test (-c 128 -n 1 -ngl 0 --no-conversation --single-turn --simple-io --no-warmup) and remote LFS/Xet SHA-256 verification.

This distillation transfers examples, not tensors. It does not make a 4B model equivalent to the sum of two architectures, and the reported held-out metrics are not broad benchmark claims. Tool calls are text emitted for an external runtime to validate and execute.
