I would gladly pay the subscription fee if OpenAI wouldn't neuter GPT-4 on their website. I'd even pay more to get access to a more powerful and less restricted GPT-4, but I know that'll never happen due to legal reasons.
Edit: I think phind.com switched to ChatGPT-4 Pro. They used to use GPT-4 API but after the switch, there's a noticeable degradation in quality of responses. :(
