Pushing OpenAI Codex to the Limit: 4-Hour PR Grind Burns 9% of Weekly Credits

Developer Andrei Marafioti shared an extreme test of OpenAI Codex, where the agent grinded on a single PR for almost 4 hours. This intensive task consumed 9% of his weekly compute credits on the $200/month plan.
He calculated that maxing out the 100% weekly allowance would equate to 15 million output tokens. Based on the rumored pricing for the GPT 5.6 Sol model, this volume of compute would actually cost $450, highlighting the heavy token consumption of autonomous coding agents.
