UnverifiedWhen appending a question to a 42,000-token conversation history, staying in the existing session costs 0.9 cents, starting a new session costs 1.8 cents, and running compact before asking costs 6 cents—nearly 7 times more expensive.64% similarUnverifiedExtrapolated at 1 million requests per day over 30 days per month, Fable 5.1 could save about $211,000 per month while Haiku 5.5 saves only about $1,900; this extrapolation is arithmetic based on the measured per-request cost, not another actual measurement, and excludes HotKV's own hosting and operations costs.64% similarUnverifiedSending a request to gpt-6.1-sol with content consisting solely of 'hi' returned a prompt_tokens value of approximately 4,223 (consistently between 4,223 and 4,227 in retests), indicating a fixed input overhead of approximately 4,200 tokens.64% similarUnverifiedAfter crossing the 100K token pricing cliff, a Haiku 5.5 request still costs 37.5% of the price of Sonnet 5.5 for the same request (calculated at gateway prices), or one quarter at Anthropic list prices.64% similarUnverifiedIn a 40-turn conversation test using claude-sonnet-5 (input $0.3835/1M, output $1.5339/1M), the full-history strategy cost $0.001599 per message, a sliding window of the most recent 6 turns cost $0.000413 (about −74%), and summary plus the most recent 4 turns cost $0.000388 (about −76%).63% similar
