Darwin-397B-JGOS — Darwin V9 Platform · 397B MoE · GPQA 90.9 % (Pure Greedy)

Largest Darwin model · Qwen 3.5 397B base + Darwin V9 FFN transplant · 397B MoE (~17B active) · BF16

GPQA Diamond: 90.9 % — pure greedy, single-sample, NO test-time engine

Overview

Darwin-397B-JGOS is the largest and highest-scoring member of the Darwin family. Built on Qwen 3.5 397B as the base, it transplants the FFN (expert) strengths of multiple high-performance models through the Darwin V9 platform, producing a 397B-parameter Mixture-of-Experts model with ~17B active parameters per token.

It reaches 90.9 % on GPQA Diamond with pure greedy decoding (single sample) — surpassing Darwin-28B-REASON (89.39 %, achieved with the Darwin-DELPHI test-time engine) without using any test-time engine at all. This is the highest GPQA Diamond score in the Darwin family to date.

🧬 Darwin Platform & Research

Darwin is VIDRAFT's measuring-result-driven reasoning model family — approximately 20 official models plus 400+ community derivatives, ranking among the top open models on GPQA.

Darwin V9 platform — evolutionary FFN/expert transplant and trust-weighted merging onto large-scale MoE backbones.
FINAL Bench — VIDRAFT's evaluation framework.
4-layer Pre-AGI roadmap — Darwin → AETHER → PROMETHEUS → HEPHAESTUS.

🧬 Model Lineage

| Role | Model | Contribution |

|:---:|:---|:---|

| Base | Qwen 3.5 397B (A17B) | 397B Mixture-of-Experts backbone (~17B active). |

| FFN transplant | Darwin V9 platform (proprietary) | Transplants the FFN (expert) strengths of multiple high-performance models onto the base. |

| Result | Darwin-397B-JGOS (this model) | 397B MoE → 90.9 % GPQA Diamond, pure greedy. |

The full Darwin V9 merge recipe — source models, weighting, and density — is proprietary and not disclosed (trade secret).

🔬 Core Technique — Darwin V9 Platform

Darwin V9 transplants the FFN (expert) strengths of multiple high-performance models onto a Qwen 3.5 397B MoE base, then applies trust-weighted evolutionary merging.

The source models, merge weights, and density schedule are proprietary and constitute a trade secret; they are not published.

🏆 Benchmark — GPQA Diamond (198 questions)

GPQA Diamond is a 198-question, PhD-level graduate science reasoning benchmark.

| Model | Engine | Accuracy |

|:---|:---|:---:|

| Darwin-28B-Opus | Standard | 88.89 % (176 / 198) |

| Darwin-28B-REASON | Darwin-DELPHI (test-time) | 89.39 % (177 / 198) |

| Darwin-397B-JGOS | Greedy (single-sample, no engine) | 🥇 90.9 % (180 / 198) |

Reproducible evaluation settings:

Greedy decoding (temperature = 0), single sample — no voting / self-consistency / test-time engine
Max generation: 16,384 tokens
Answer options shuffled (seed = 42)
Hardware: NVIDIA B200 (tensor-parallel 2 × pipeline-parallel 3, 6 GPUs)
Inference engine: vLLM, bfloat16, max_model_len = 18432

Darwin-397B-JGOS achieves the family's top GPQA Diamond score using nothing but greedy decoding — no Darwin-DELPHI, no majority voting.

🚀 Usage (vLLM)


vllm serve FINAL-Bench/Darwin-397B-JGOS --tensor-parallel-size 2 --pipeline-parallel-size 3 --dtype bfloat16 --trust-remote-code

🎯 Recommended Use-Cases

Graduate-level STEM reasoning (GPQA / science qualifying exams)
Mathematical problem solving
Complex multi-step chain-of-thought
Code generation and debugging
Bilingual reasoning (strong English + Korean; also Chinese / Japanese)

⚠️ Limitations

397B MoE in bfloat16 requires multi-GPU serving (e.g. B200 ×6 with TP2×PP3).
The 90.9 % figure is a single-run greedy measurement on GPQA Diamond (198 items).
Reasoning traces can be verbose — control with max tokens.
