ORCA conformal prediction for test time compute efficiency

April 5, 2026Valeriy M., PhD, MBA, CQF

Valeriy M. summarizes ORCA as reducing wasted test-time compute by dynamically choosing how many reasoning samples to draw per question using conformal prediction. The pitch is large compute savings without sacrificing accuracy.

“Most “test-time compute” scaling wastes a ton of samples.”
“ORCA uses conformal prediction to dynamically calibrate exactly how many reasoning samples an LLM actually needs per question.”
“→ 47% compute”
