Unverified模型规模越大，记忆能力反而越强，因为更大的模型拥有更强的参数容量来存储低频样本77% similarUnverifiedIn cache-intensive, long-context, multi-turn agent workflows, the incremental cost of switching to a more powerful model is diluted by cache reads and does not necessarily mean costs double.74% similarUnverifiedThe vector dimensionality of embedding models ranges from 768 to 3072 dimensions, affecting the trade-off between precision and storage cost.72% similarUnverifiedAccurately estimating a model's VRAM usage requires considering multiple dimensions including KV Cache, inference framework runtime overhead (typically an additional 0.5–2 GB), and activation values.70% similarUnverifiedThe cost of HNSW is relatively high memory usage, typically requiring 1.5 to 2 times the raw vector data size in additional space to store the graph structure.69% similar
