Today, Amazon Lex increased the default service limits for intents and slot types. With the increased limits, you can expand the bot to support additional conversation flows. You can now create up to 1,000 intents and 250 slot types for English locales, an increase from previous limits of 100 each.

Amazon Lex is a service for building conversational interfaces into any application using voice and text. Amazon Lex provides the advanced deep learning functionalities of automatic speech recognition (ASR) for converting speech to text, and natural language understanding (NLU) to recognize the intent of the text, to enable you to build applications with highly engaging user experiences and lifelike conversational interactions. With Amazon Lex, you can quickly and easily build sophisticated, natural language, conversational bots (“chatbots”), virtual agents and IVR systems.

The higher limits are automatically available for English locales on Lex V2 API. For more information, please see the Amazon Lex service limits documentation.
