Sliding Window Attention (SWA)
An attention variant where each token only attends to a limited number of previous tokens (window) instead of the entire sequence.
SWA limits attention to local window – O(N) instead of O(N²), enables efficient long contexts.
Explanation
With window size W, each token only attends to the last W tokens. Reduces compute from O(N²) to O(N×W). Through deep networks, information can still flow across full context (W tokens per layer, after L layers L×W effective context).
Marketing Relevance
SWA is core to Mistral architecture and enables efficient processing of long contexts. Combined with sparse attention for global tokens.
Example
Mistral 7B with 4096 window and 32 layers has effective context of 131K tokens but only ~4K tokens compute cost per token.
Common Pitfalls
Direct attention only within window – information from distant tokens must "flow" through layers. Can lead to information loss with very long contexts.
Origin & History
Local attention was introduced in Longformer (2020) and BigBird (2020) for document processing. Mistral (2023) popularized SWA for general-purpose LLMs.
Comparisons & Differences
Sliding Window Attention (SWA) vs. Full Attention
Full attention is O(N²); SWA is O(N×W) with constant window W, much more efficient for long sequences.
