$20 buys you o3 access. I have not run into limits for personal or professional information or research purposes. I am sure you can.

Last time I had access to o3 on a $20 subscription, the usage limit was laughably low. Accessing it through an API is much better value - I get over 1000 interactions with a much more controllable system message, which is a lot better than ChatGPT Plus.

		Was that a pretty long time ago? Because I use o3 daily and have never hit a limit. The only "limit" I have really with o3 is my patience -- it's a slow model for regular use. If I don't need its intelligence I'll use o4-mini or even 4o for speed, saving o3 for the prompts that really need it. These days the only model I find I get rate-limited on frustratingly quickly is 4.5. It's clear OpenAI does not really want you using that one, despite the fact that's very good (and probably very expensive for them)! Pretty underrated imo.
