Hugging Face publishes multi-harness RL guide: the same model scores 62% versus 33% with different harnesses
What happened
The Hugging Face team published a multi-harness RL guide, showing that the same model with identical weights can score 62% with one agent harness and 33% with another.
Why it matters
Scores for the same model differ by nearly half across agent harnesses. This open guide gives a multi-harness RL training path without changing the harness, along with measured comparisons.
