o3 model with premium credits like 30 messages per month

Is it possible to add o3 just like you added o4-mini but with premium t3 chat credits?

I know at $10.00 it is even costlier than Calude, so maybe 30 messages per month? It's probably around the same intelligence as o4-mini, so people can instead just use o4-mini in most cases, but in rare cases, o3 might be more accurate. I use t3 chat for theoretical physics/maths, so I never use Calude as it's only good at coding, and Grok 3 is useless for anything. o3 will be more useful for premium credits.
