GPT 6 Astra High vs GPT 6.1 Sol High/Extra High

I'm creating a trading bot, and I've been letting Astra do the backtest and research on trading strategies but just 1 prompt would already eat up 100% of the 5-hour limit and a good chunk of the weekly limit when using GPT 6 Astra High. I haven't tried GPT 6.1 Sol High/Extra High but from what I've been reading so far it is just a slower and slightly dumber version of GPT 6 Astra but with much better token consumption. My priority would of course be the model that would be able to do what I am actually envisioning, so any discrepancies or recommendations you guys give would be appreciated. I've also been using ChatGPT to create the prompt to feed into Codex so not sure if that is really recommended lol
