Context is very important in these kinds of use cases. If you work with something niche, I think these tools are less valuable because the training data becomes sparse.
For example, GPT-4 produces Javascript code far better than it produces Clojure code. Often, when it comes to Clojure, GPT-4 produces broken examples, contradictory explanations, or even circular reasoning.
