I ran $24,000 of Claude through my terminal in August. Here is what it built.

Open-source maintainer and creator of the Iris web framework, kataras, shared a detailed report on his intensive use of Anthropic's Claude Code during August 2026. Participating in the Claude for Open Source Program, he utilized the platform's highest-tier subscription to accelerate the development of Iris v14. Over 29 days, he processed 31.17 billion tokens, with an API-equivalent cost of nearly $24,000. The author highlights the efficiency provided by prompt caching, which accounted for 98.2% of the token processing. The massive AI-assisted effort resulted in 351 commits, including the implementation of Server-Sent Events, a new AI package, and comprehensive documentation updates. The author emphasizes that while AI significantly boosted his productivity, it remains a tool requiring human oversight, particularly for complex architectural decisions and code quality maintenance, ultimately enabling him to manage multiple projects simultaneously with unprecedented speed.
