Build AI Apps with ChatGPT, Dall-E, and GPT-4

This course teaches web developers to build apps using OpenAI's API, helping them take their first steps as an AI Engineers. Learners will get hands-on practice with both the GPT-4 and Dall-E APIs, using OpenAI's JavaScript SDK. In the first project, MoviePitch, you will get a primer on the OpenAI API and harness the power of artificial intelligence to generate ideas and images. In our second project, KnowItAll, we’ll move to the ChatGPT-4 model and get to grips with building chatbots - one of the most common uses of AI for web devs. Finally, we will fine-tune our chatbot in the third project. Fine-tuning is where you upload a dataset to OpenAI and use it to train a model. Doing this allows the chatbot to answer questions specific to your data - a critical skill when working with AI.
