ChatGPT

by OpenAI

ChatGPT, powered by OpenAI's GPT-4o model, is the most widely adopted large language model globally. It excels at general-purpose reasoning, code generation, and multi-modal tasks. For mobile app development, GPT-4o is accessible via OpenAI's API with structured output support, function calling, and streaming — making it well-suited for building conversational interfaces and intelligent automation within React Native apps.
