I’ve just tried building my first agent using Relevance AI. While the learning curve was steep at first, I can definitely see myself getting good at it soon. When following Liam’s Co-pilot agent build from the Ultimate Beginner’s Guide, I ran into a few issues—mainly realizing too late that having ChatGPT Plus doesn’t mean my OpenAI API key has access to GPT-4 or other higher-tier models. I ended up burning through most of my Relevance credits on tools that didn’t run properly. So my main question is: would it be smarter to upgrade my Relevance AI account for more credits, or my OpenAI plan for better model access? Any insight is appreciated.
