UnverifiedUnder the mechanism in which large models bill by input and output tokens, resending the full browsing history every day causes the input token cost to grow linearly with the number of days of use; having the client perform deduplication, aggregation, or incremental summarization can keep the input volume at a roughly constant level.80% similarUnverifiedReasoning content is often billed the same as regular text in terms of token counting, so retaining reasoning increases the number of tokens carried in requests and affects call costs.77% similarUnverifiedCompared to per-token pricing, per-minute pricing may result in higher costs for high-frequency short-utterance scenarios such as customer service conversations.77% similarUnverifiedFor agent or chat products that resend long system prompts and history on every turn, cache prices may have a greater impact on the bill than input prices.77% similarUnverifiedClaude Code's API billing typically prices input tokens and output tokens separately; the linear accumulation of input tokens across conversation turns is the primary driver of cost inflation in long tasks.77% similar
