I'm personally only using it for experiments and I continuously get disappointed, but this is how we learn. I feel more optimistic about LLMs than I was during peak hype, there is definite progress being made, but I see several issues still that need to be addressed: quality (I can't help but feel that there's still a massive garbage in, garbage out issue that gets attempted to be suppressed with RL), cost (Claude 4 Sonnet test cost me approximately 10k sats for a minor bug fix, 50k sats for a half-coded feature that still has bugs) and UX (chatbots are the worst interface.)
