Libraries

How to use abcsk123/PyraCode-1.5B with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="abcsk123/PyraCode-1.5B", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained("abcsk123/PyraCode-1.5B", trust_remote_code=True, device_map="auto")

PyraCode-1.5B

🌟 Model Overview

This is a custom-architected model based on Qwen2.5-Coder-1.5B. We introduced a novel Asymmetric Hybrid Architecture (GQA + MLA) with Cross-Layer Shared Latent Gates and Attention Sinks, enabling efficient feature communication and reduced KV-Cache memory footprint.

🏗️ Architecture Innovations

Unlike standard Qwen2 models, this Hybrid-v9 backbone features:

Asymmetric Layers:
- L0-L6: Standard GQA (Grouped-Query Attention) for robust low-level feature extraction.
- L7 (Shared Hub): Generates a global latent vector $c_{kv}$ (Rank 320).
- L8-L27: Soft MLA (Multi-Head Latent Attention) with SVD-initialized low-rank projections.
Shared Latent Gate: Deep layers can dynamically access the global latent vector from L7 via a learnable gating mechanism (warmup_alpha).
HybridCache & Attention Sinks: Implements a sliding window (8192) alongside a 64-token attention sink to maintain generation stability at infinite sequence lengths.

🚀 Quick Start

⚠️ IMPORTANT: This project is not fully completed yet, and the current weighting is not a very good tradeoff. If I obtain new training results in the future, I will continue to update them here

If you have decided to test this not-so-perfect weight, please be aware： Because this model uses a custom architecture, you MUST pass trust_remote_code=True when loading it.
