# Harness2 And Hermes Open Source

Google just open‑sourced Harness².

Nous Research's Hermes sits at 253K stars.

Both make agents smarter without touching the model.

Hermes learns from living.

Harness² learns by experimenting.

I decided to publish Harness² as open source to let the community experiment widely, and to position Hermes as a learning‑from‑living system to leverage real‑world feedback.
