Why people look for alternatives to Gorilla

The complaints that come up most often in public discussion — reviews, forums and community threads. Not our opinion, and not the vendor's marketing.

  • 265 open issues on GitHub hint at maintenance challenges.
  • Almost no real-world community validation or case studies.

In fairness: users also consistently praise open-source (apache 2.0) and free to use commercially, and performance on function calling benchmarks is on par with gpt-4. A complaint list is not a verdict — see the full picture on the Gorilla page.
