Caution
Caution: one person wrote most of the recent commits.
Why
- One person wrote 80% of human commits in the last year, so the project depends on them continuing. (source 1, source 2)
- The PyPI package gptcache has had no release since August 2024, while the repository has 10 human commits in the last year. (source 1, source 2, source 3, source 4)
What would change this
- A second person takes a substantial share of commits.
- A new package release is published.

Stars
CompleteOrganic, confidence high
Bursts

Anyone can buy stars for any repo; bursts alone don't prove the owner did.
- The star history looks organic.
