GPT-OSS: Architecture Implementation
This comprehensive Jupyter notebook provides a hands-on, implementation-focused on exploration of the GPT-OSS (Open Source) model architecture. It builds working components and integrates them into a complete model.
π οΈ Hands-On Implementation
- Working code for all major GPT-OSS components
- Live demonstrations showing tensor operations
- Performance comparisons between architectures
- Complete model integration with error-free execution
- Interactive visualizations of attention patterns and expert usage
π Table of Contents
- ποΈ Core Architecture Components - Build RMSNorm, RoPE, Attention, MLP blocks
- π€ Advanced Tokenization - o200k encoding with conversation tokens
- π§ Model Integration - Complete GPT-OSS vs GPT-2 comparison
- π Training & Scaling Analysis - Memory, compute, and performance insights
π GPT-OSS Architecture Highlights
This notebook implements and demonstrates:
- π Mixture of Experts (MoE): 8 experts with 2 active per token (4x capacity, 25% compute)
- π Grouped Query Attention (GQA): 4:1 query-to-key ratio for memory efficiency
- π Rotary Position Embedding (RoPE): Relative positions without learned parameters
- π RMS Normalization: Simpler, more stable than LayerNorm
- πͺ Sliding Window Attention: Efficient long-context processing
- π§ Advanced Tokenization: 200k+ vocabulary with special conversation tokens
