\nWeb search (all models): $10.00 \/ 1k calls + search content tokens billed at model rates
…(\u7565)
Web search: There are two components that contribute to the cost of using the web search tool: (1) tool calls and (2) search content tokens. Tool calls are billed per 1000 calls, according to the tool version and model type. The billing dashboard and invoices will report these line items as \u201cweb search tool calls.\u201d
Search content tokens are tokens retrieved from the search index and fed to the model alongside your prompt to generate an answer. These are billed at the model\u2019s input token rate, unless otherwise specified.<\/p>\n
