Amazon Lex Pricing
With Amazon Lex, you pay only for what you use. There is no upfront commitment or minimum fee. Pricing for Lex is based upon these two interaction models.
Request and Response Interaction Pricing
With the request and response interaction, each user input is processed as a separate API call. You are charged based on the number of speech or text API requests processed by your bot.
Streaming Conversation Pricing
In a streaming conversation, all user inputs across multiple turns are processed in one streaming API call. The bot continuously listens and can be designed to respond proactively. You are charged based on the number of speech intervals or text requests that take place.
If your application on a daily basis has a Amazon Lex bot which process 5000 speech requests and 2000 text requests, following is the cost per day
|Cost per request
