NEXUS Shared Expert Weights (10K Steps)

Trained shared expert weights from NEXUS (Neural Expert Unified Specialization) calibration run.

Model Details

Base Model: GPT-OSS 120B
Training Steps: 10,000
Method: Top-24 PCA-selected experts, frozen router
Parameters: 896,106,240 (shared expert only)
Size: 1.67GB (BF16)
Training Config: Frozen router, advanced scheduler, KL distillation

What This Contains

This file contains ONLY the shared expert weights (216 parameter tensors) from a NEXUS-trained model.

To use:

Start with base GPT-OSS 120B model
Add NEXUS shared expert architecture
Load these weights

Usage

import torch

# Load weights
shared_weights = torch.load("nexus_shared_expert_weights_10k.pt")

# Apply to model with NEXUS architecture
model.load_state_dict(shared_weights, strict=False)

About NEXUS

NEXUS enables efficient domain specialization of massive MoE models by training a small shared expert while keeping routed experts frozen.
