The recently announced GPT-4 Chat model will work the same way as the model demonstrated in this video, except the token limit has increased substantially.

In this video, we cover how to build and deploy your own full-stack AI application using SvelteKit, OpenAI's newest ChatGPT API / Chat Completion Model (gpt-3.5-turbo) APIs, and Vercel Edge Functions. The new ChatGPT API is 10x cheaper and much faster than GPT-3. We also learn how to handle moderations, token limits, and more.
