UnverifiedCaching the results of repeated requests (such as recurring email classification patterns) reduces the number of API calls and lowers costs.74% similarUnverifiedSome vendors have introduced context caching (Prompt Caching) features, charging lower fees for repeatedly occurring long prefixes.72% similarUnverifiedCache hits reduce the billing rate per request, not the absolute amount of tokens consumed.71% similarUnverifiedBatch mode compresses the number of requests to a single digit, which can bypass the RPM bottleneck and amortize the fixed overhead of the system prompt, reducing the average cost per item.69% similarUnverifiedWhen an inference service serves a large number of concurrent requests simultaneously, batching is the core means of driving down per-unit costs.68% similar
