+### use_tf32
+
+TF32 is a math mode available on NVIDIA GPUs since Ampere. It allows certain float32 matrix multiplications and convolutions to run much faster on tensor cores with [TensorFloat-32](https://blogs.nvidia.com/blog/tensorfloat-32-precision-format/) reduced precision: float32 inputs are rounded with 10 bits of mantissa and results are accumulated with float32 precision.
+
+Default value: 1
+
+TensorFloat-32 is enabled by default. Starting from ONNX Runtime 1.18, you can use this flag to disable it for an inference session.
+
+Example python usage:
+
+```python
+providers = [("CUDAExecutionProvider", {"use_tf32": 0})]
+sess_options = ort.SessionOptions()
+sess = ort.InferenceSession("my_model.onnx", sess_options=sess_options, providers=providers)

 If this is enabled the EP prefers NHWC operators over NCHW. Needed transforms will be added to the model. As NVIDIA
 tensor cores can only work on NHWC layout this can increase performance if the model consists of many supported
 operators and does not need too many new transpose nodes. Wider operator support is planned in the future.
