Optimize your Amazon Lex costs with these tips
Use Hugging Face
If you are using Amazon Lex at scale, you might consider hosting your own Hugging Face Conversational bot. You can use Amazon SageMaker to get started with this. It would mean refactoring your application to use the SageMaker inference endpoints.
Switch to Request / Response
Amazon Lex has two modes of operation, request / response, and streaming conversation. Depending on your use-case it might be more cost efficient to reduce the complexity of your chatbot by switching to request / response as this is around 40% cheaper.
Consider Alternatives
If you are using your bot as a conversational agent, you might be better off switching to alternatives like ChatGPT. The pricing model is different as the ChatGPT API works with token counts instead of text requests. If you have short text ChatGPT might be more cost effective.
