Every time I use it for code, it suggests using APIs that don't exist but definitely look like they could. If asked it can go on in great detail talking about the mundane details completely convincingly of APIs that either don't exist or have completely different structure than what is described. On the other hand it is really good at tasks like "turn this XML in JSON and give me a JSON Schema definition for it".
