ONNX Runtime v1.31.0 exposes a per-session deterministic-compute switch (config key session.use_deterministic_compute / OrtApi::SetDeterministicCompute), while the CUDA execution provider defaults to exhaustive cuDNN convolution algorithm search and TF32 on - both outside that switch.

ONNX Runtime v1.31.0 exposes a per-session deterministic-compute switch (config key session.use_deterministic_compute / OrtApi::SetDeterministicCompute), while the CUDA execution provider defaults to exhaustive cuDNN convolution algorithm search and TF32 on - both outside that switch. Curator qualifications: Which kernels honour the flag, TensorRT engine portability, random-op seeding and KleidiAI/regression reports (F1, F3-F6) not reinspected. No ORT website determinism page (F3) is a producer negative. Docs/headers only; no model run. Limitations: Docs/headers only; no model run. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
