My guess is most people into AI don't even remember that they are paying a $20/month for this. We do a lot of experiments involving gpt3.5, 4, claude-v2, titan-large, and palm2, and for what it's worth, on our real production workloads gpt4 shines. We can make Palm2 produce decent results with a lot of extra effort, and claude-v2 is passable but gpt4 does not disappoint. This is low-grade knowledge management stuff, and we are not using it as a information-retrieval system - but for basic 'cognitive' tasks where all the information needed is provided in the prompt. I'd not rely on it for info retrieval tasks such as the examples quoted above - its knowledge base is highly compressed, after all.
