GPT-6.1 Sol Ultra is the best deal for your GPT subscription with all these Tibo's resets It's a bit slower, but it's really thorough OpenAI ran the same audit on 1M lines of their own code and checked every finding by hand: Astra Ultra: 142 issues, $109 Sol Ultra: 131 issues, $15 92% of the work for 14% of the cost With all these usage resets, this is how I use it now: 1. Sol Ultra for deep, thorough work 2. A few agents running in parallel on different tasks 3. Astra only when I really need it I will share soon what I used it for and its results!
