SUSPICIOUSLY PRECISE FLOATS, OR, HOW I GOT CLAUDE'S REAL LIMITS

Summary from the TLDR Dev newsletter

This dev reverse-engineered Claude's hidden usage limits and internal credit system by analyzing unrounded float values from the API. Findings show the 5x subscription plan has amazing value, providing much more usage (up to 8 times weekly) than advertised, while the 20x plan is less efficient for weekly tasks. Subscription plans are always superior to API pricing, mainly due to free cache reads and discounted cache writes.
