UnverifiedThis configuration achieves three optimizations—262K ultra-long context, KV Cache Q4 quantization, and MTP speculative sampling—pushing 24GB VRAM utilization to 99%68% similarVerifiedPagedAttention splits the KV Cache into fixed-size physical blocks mapped via a block table, and can improve GPU utilization from below 40% to above 90%.67% similarVerifiedThe VRAM consumption of the KV cache is proportional to context length, number of model layers, and number of attention heads; under an 8K context, a typical 27B model may consume an additional 2–4 GB of VRAM.67% similarUnverifiedMiniMax's new architecture reduces prefill compute consumption by approximately 5x and shrinks the KV cache by approximately 4.5x under million-level context by sharing KV cache across layers and using an intelligent filtering attention mechanism.66% similarUnverifiedThe computational cost of long-context attention grows quadratically with sequence length, and Key and Value vectors must be cached for each token (KV Cache), which at a 1M context can reach hundreds of GB.66% similar
