SWE-Pruner Pro — Coder Next Head Pruning Head

A lightweight pruning head for Qwen3-Coder-Next (80a3 MoE, Qwen/Qwen3-Coder-Next), from the paper:

SWE-Pruner Pro: The Coder LLM Already Knows What to Prune arXiv: 2607.18213

Overview

This head attaches to the frozen backbone and predicts per-token keep/prune logits from the backbone's hidden states. It is used to compress tool responses in long-horizon coding agent trajectories.

Architecture: LayerNorm → Linear(d,d)→GELU→Dropout → Linear(d,d)→GELU→Dropout → Linear(d,1) + 8-bucket size embedding
Parameters: ~18M
Hidden size: 2048

Usage

python

from huggingface_hub import hf_hub_download

# Download checkpoint
for fname in ["best_model.pt", "model_config.json"]:
    hf_hub_download(repo_id="ayanami-kitasan/swe-pruner-pro-qwen3-coder-next-head", filename=fname, local_dir="./checkpoints/coder-next-head")

# Load the pruning head
from swe_pruner_pro.model.head import PruningHead

head = PruningHead(checkpoint_dir="./checkpoints/coder-next-head", hidden_size=2048, device="cuda:0")
