Fusion vs N2 (Nex-N2-Pro)
Multi-model panel — Fable 5 + GPT-5.5, ensembled. Beats Fable 5 at half the price. vs Free local frontier model — runs in Hermes for $0.
What I tested — same prompt, two models
I run the same fixed prompt set through every new model the day it drops — same string, one shot, single HTML file out — and I score the result 0–10 on whether it ran, how close it hit the brief, and how good it looked. Below is what came out when I gave the exact same prompts to Fusion and N2 (Nex-N2-Pro), side by side, on 0 shared tasks inside the Agent Operating System.
Both models were given identical prompts inside the Agent Operating System — no help, no iteration, no "best of N" tricks. I run each prompt once, save the HTML file the model produces, and score it 0–10 on whether it ran, how close it hit the brief, and how good it looked. The scoring is mine. The verdicts below are pulled from my source comparison guides at agentos.guide where I publish every score and the reasoning behind it.
Fusion · Dispatched from Agent OS for research-heavy prompts where ensemble accuracy outweighs single-model speed.
N2 (Nex-N2-Pro) · Wired into Hermes as the free local frontier coder. Dispatched from Agent OS for any task where the per-token bill would dominate.

Strengths & weaknesses I logged
Fusion
Strengths
- Premium Fusion panel scored 69.0% on DRACO deep-research benchmark — beats solo Fable 5 by +3.7 points
- Budget panel ties Fable 5 at ~64.7% for roughly half the cost
- Vendor-agnostic — model panel can swap as new frontier releases land
Trade-offs
- Ensemble latency higher than any single model (panel calls run in parallel but the slowest still gates the response)
- No per-task goldiebench scoring yet — bench rank pending
N2 (Nex-N2-Pro)
Strengths
- Vendor-reported 80.8% on SWE-bench Verified — top of the free open-weights field
- Runs locally inside Hermes — no token meter, no rate limits
- Builds two playable 3D games in one-shot per Julian's three-dragons writeup
Trade-offs
- Vendor-reported benchmark (not independently verified yet)
- No goldiebench per-task scores yet

The verdict — which should you pick?
Not enough scored shared tasks yet for a head-to-head average. The live demos for both are on the matrix above — play them and form your own opinion.
If you only run one of these inside your stack, the head-to-head average above is the call. If you can run both, my honest play is to wire Fusion and N2 (Nex-N2-Pro) both into the Agent Operating System and dispatch each from the kanban by task type — deep-research workflows where panel consensus beats single-model answers → Fusion, local agent loops that need a free frontier-class coder → N2 (Nex-N2-Pro). That's the same setup I run for the 3,600+ founders inside the AI Profit Boardroom.

Fusion has a Varies — depends on which panel models are dispatched context window. N2 (Nex-N2-Pro) has a Specs not yet public context window.
When should I pick Fusion over N2 (Nex-N2-Pro)?
Pick Fusion for: Deep-research workflows where panel consensus beats single-model answers; Cost-sensitive operators who want Fable-5-class output at ~half the bill; Production agents that benefit from vendor-redundancy on every call. The trade-off is the weaknesses we logged on the bench: Ensemble latency higher than any single model (panel calls run in parallel but the slowest still gates the response); No per-task goldiebench scoring yet — bench rank pending.
When should I pick N2 (Nex-N2-Pro) over Fusion?
Pick N2 (Nex-N2-Pro) for: Local agent loops that need a free frontier-class coder; Privacy-sensitive workflows (no cloud round-trip); Operators experimenting with Hermes who want to compare local models against the cloud field. The trade-off is the weaknesses we logged on the bench: Vendor-reported benchmark (not independently verified yet); No goldiebench per-task scores yet.
How does Goldie Bench score Fusion vs N2 (Nex-N2-Pro)?
Every demo on this page was built by Julian Goldie inside the Agent Operating System — same fixed prompt for both models, one shot, single HTML file out. Each result gets a 0–10 score on whether it ran, how close it hit the brief, and how good it looked. The highest score on each task gets gold; second gets silver; third gets bronze. See methodology for full provenance.
