UnverifiedThe KV Cache mechanism can cache repeated prefix content, and the more concise the system prompt, the higher the cache hit rate.75% similarUnverifiedMainstream model providers (such as Anthropic and DeepSeek) support prompt caching mechanisms, and reusing the KV Cache of identical prefix contexts can save 50%–90% of input costs.72% similarUnverifiedSemantic caching converts queries into vector embeddings and calculates cosine similarity to identify semantically equivalent queries, which can reduce actual API call volume by 30%–70%.72% similarUnverifiedConstrained Decoding computes the set of valid tokens at each token step of autoregressive generation based on a finite state machine or context-free grammar and renormalizes the probabilities, mathematically guaranteeing that the output conforms to the target schema.69% similarUnverified借助编辑器现成能力可降低编程智能体获取高质量上下文信息的接入成本，无需自行实现复杂的代码语义分析68% similar
