estimated usage cost
$0.35
1,000 requests × (1,000 uncached input × $0.10 + 500 output × $0.50) / 1,000,000 = $0.35

brackets are by input tokens per request: a request over a threshold is billed at that bracket's rates for all of its tokens. cache creation can have a separate charge. the estimate below prices one workload at these rates on every model.
