BREAKING CHANGE: Restructured model.py into dedicated modules under inference/models/ Key Changes: - Split monolithic model.py into focused, single-responsibility modules: - config.py: Model configuration and hyperparameters - attention.py: Multi-head Latent Attention (MLA) implementation - moe.py: Mixture of Experts components (Gate, Expert, MoE) - linear.py: Linear layer variants with parallel processing support - __init__.py: Clean public API exports Benefits: - Improved code organization and maintainability - Better separation of concerns - Enhanced testability of individual components - Clearer dependency management - Simplified future modifications and extensions Migration: - Update imports to use new module structure - No functional changes to existing implementations - Backwards compatible with current model weights
