Getting an API key has been just a waiting game here... Not been approved through work or personally yet after almost 3 months. I already have plugin access though, it's...alright. The web browsing leaves a ton to be desired.
Ya, I'm not sure why I got lucky to receive one. For coding tasks, gpt-4 really is significantly better than 3.5. I've been building tools for coding with GPT for a few months now, and they got way more effective and reliable with gpt-4.
The thing I've used browsing for the most is linking to lengthy markdown files for large initial prompts with heavy detail. It works alright. Not perfect but decent.
