Integrating AI into products involves challenges like neural network requirements, computational load, and compliance, which PubNub addresses with its Functions platform and OpenAI GPT API integration. Functions, a serverless compute platform, allows code execution closer to users, improving performance and reducing latency. PubNub manages infrastructure, enabling developers to focus on product development without worrying about servers. The integration of OpenAI GPT offers developers access to advanced AI capabilities, facilitating tasks such as natural language processing and code optimization, demonstrated by a 30% reduction in code footprint in tests. This integration streamlines AI incorporation, saves time and resources, and enhances innovation across industries like law, software engineering, sales, and marketing. As serverless solutions rise in prominence, PubNub's APIs simplify AI integration, enabling developers to build user-friendly applications without the need for extensive infrastructure or model training.
