GPT 6 Astra low VS GPT 5.6 Sol High?

Hey everyone! Question. So, I own a small business which I have never ever been a fan of using AI but come to see with 5.6 sol I've actually been impressed with the work it's done. I have the $25 business plan with 2 seats and I am using the credit system for usage at the moment. We completed a big dev project totalling probably over $7000ish this month for our new system which actually came out extrememly well. Since the release of GPT 6 i was hesitant to switch knowing it is more expensive but decided to give it a shot. The work was insane (in a good way lol) and I was very happy with its outcomes. This leads me into my question that I've always used 5.6 sol low and started using astra low since i feel its the first time i talk to it and its not "stupid". Listens to what i say and gives output. I have the auto top up for around $1000 so with the 40% off im paying $600 each time to top. Since my main bulk dev work is complete I want to use it now for helping me run that system, so essienitcally coming up with the ideas, and utlizing my apps workflow. It shouldnt be that intense work compared to some things you guys are building I imagine. However I've been going back and forth to understand what model I should use. I dont want to run through credits like crazy to cut back on some of the spending weve done for that previous project i told you about before. I know it depends a lot on use case but im curious to hear what you guys are running and recommend to find that balance between performance and price. Thank you everyone!
