--- title: AI Coding Agent Subscription ROI date: 2026-05-30T23:19:34+08:00 categories: - llms - coding --- I ran [`npx -y ccusage monthly --compact`](https://github.com/ryoppippi/ccusage) to get the following break-up of my AI coding agent costs. | Month | Codex | Claude | | ------- | -------: | ------: | | 2025-09 | $37.47 | $2.29 | | 2025-10 | $106.79 | $9.13 | | 2025-11 | $100.35 | $14.24 | | 2025-12 | $240.69 | $24.88 | | 2026-01 | $100.89 | $20.28 | | 2026-02 | $323.21 | $29.46 | | 2026-03 | $1996.32 | $134.87 | | 2026-04 | $401.36 | $47.07 | | 2026-05 | $378.20 | $45.13 | This shows the ROI of my $20 subscriptions to each. I get ~$35 worth of API calls for my $20 Claude Pro subscription and ~$400 of API calls for my $20 ChatGPT Plus subscription (on top of my ChatGPT chats.) I end up using Codex a lot more - partly because it's a bit more diligent, but mostly because it's a lot cheaper. Clearly, subscriptions are good deal for individuals. Codex, especially. This may not be true for corporates. [Simon Willison](https://simonwillison.net/2026/May/27/product-market-fit/) says that Anthropic and OpenAI both changed _enterprise_ pricing to align with token prices. That means the cost of enterprise AI security is ~2-20 _times_ their token budget - which is growing rapidly. --- BTW, my moment of [AI psychosis](https://en.wikipedia.org/wiki/Chatbot_psychosis) was in March 2026. The coding agents had increased their limits and I was tokenmaxxing. I'm far from that limit today, but the symptoms linger.
