Every case

Instability

2 cases produced both outcomes

The same prompt, the same model, different results. A single run of any of these would have been a coin flip reported as a fact.
  • ablation.page.bakery1 passed, 9 failed
  • ablation.page.studio1 passed, 9 failed

Conditions

Two runs are comparable only when all of these are identical. A score that moved because the model changed is not a regression in the skill.
