A Rough Estimate of GPT-5.6 Coding Costs

burhop · x · 2026-07-10

Someone calculated the costs based on the usage limits of GPT-5.6 Sol Ultra in Codex: under a $200 subscription, 1 hour of use depletes a 5-hour quota. At this burn rate, running Ultra 24/7 would cost about $1000/month, while maintaining 3 concurrent Ultra sessions around the clock would be roughly $3000/month.
