VerifiedIn LLM inference scenarios, GPU memory capacity is often more critical than peak compute performance.67% similarUnverifiedThe autoregressive decoding phase of LLMs is limited by memory bandwidth bottlenecks, as generating each token requires a complete traversal of the activated model weights.66% similarUnverifiedThe formula for local AI inference speed is Token/s ≈ memory bandwidth / data volume to be read per token, and large language models generate each token in an autoregressive manner.66% similarUnverifiedNormalizing flows can directly reuse the mature inference infrastructure of LLMs, including KV-cache management, tensor parallelism strategies, and inference acceleration techniques such as speculative decoding.66% similarUnverified上下文缓存技术底层依赖KV Cache机制，是vLLM、TensorRT-LLM等主流推理框架的核心优化之一66% similar
