Long Context: Extending Transformer Context Windows

When to Use This Skill

Use Long Context techniques when you need to:

• Process long documents (32k, 64k, 128k+ tokens) with transformer models
• Extend context windows of pre-trained models (LLaMA, Mistral, etc.)
• Implement efficient positional encodings (RoPE, ALiBi)
• Train models with length extrapolation capabilities
• Deploy models that handle variable-length inputs efficiently
• Fine-tune existing models for longer contexts with minimal compute

Key Techniques: RoPE (Rotary Position Embeddings), YaRN, ALiBi (Attention with Linear Biases), Position Interpolation

Papers: RoFormer (arXiv 2104.09864), YaRN (arXiv 2309.00071), ALiBi (arXiv 2108.12409), Position Interpolation (arXiv 2306.15595)
