model layers
The fundamental structural units of a neural-network, specifically the sequential blocks within a Transformer architecture that constitute a large-language-model (LLM).
Architecture & Composition
- Each layer consists of specialized operations, including Self-Attention mechanisms, Feed-Forward Networks, and Layer Normalization.
- Layers are defined by learned parameters (weights and biases) that are processed during both training and LLM Inference.
Inference & Hardware Execution
- Execution Logic: During inference, layers are not treated as simple standalone executables; rather, they are part of a complex collection of weights managed by specialized Inference Engines.
- Memory Management: The efficient running of these layers relies heavily on Memory Mapping to handle the massive data requirements of model weights.
- Performance Optimization: Optimization focuses on the technical challenges of loading and running these weight collections, specifically managing the interplay between hardware bandwidth and the structural complexity of the layers.
