Recent advancements in Large Language Model (LLM) architectures are focusing on improving efficiency for long context windows, addressing resource constraints like KV cache size and memory bandwidth. Techniques such as KV sharing, layer-wise attention budgeting, compressed attention, and modified hyperconnections are being implemented. For instance, Gemma 4 utilizes KV sharing across layers to reduce cache size, while Laguna XS.2 employs layer-specific attention budgets to allocate computational resources more effectively. ZAYA1-8B introduces compressed convolutional attention to reduce both cache size and attention FLOPs, and DeepSeek V4 incorporates modified hyperconnections (mHC) and compressed attention mechanisms (CSA/HCA) for more stable and efficient long-context processing.
