The amount of new agent APIs/harnesses are dizzying, with everyone and their dog releasing their own. Can we do a compilation thread of comparisons?

Key Points

  • The post asks the community to compile and compare the rapidly growing number of new agent APIs and harnesses being released.
  • It encourages readers who have tested multiple options to share their evaluation results.
  • The author requests detailed context, including users’ hardware specifications, software stack, and any modifications made.
  • The goal is to create a comparison thread that helps others choose among competing agent tooling.
  • The discussion is framed as a community-driven effort rather than a single product announcement.

Assuming you have tried multiple, please compare them. Please also post your hardware specs and software stack, along with any modifications.
