NVIDIA Run:ai Trainings API
Trainings are dedicated workloads that are specifically used for training models. They are by design preemptible workloads because they are used in unattended sessions where the scientists and researchers do not need to be present. These workloads are allowed to utilize resources over the project's quota.
NVIDIA Run:ai Trainings API is one of 62 APIs that NVIDIA Run:ai publishes on the APIs.io network, described by a machine-readable OpenAPI specification.
Tagged areas include Trainings. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and authentication docs.
This API exposes 5 operations across 4 paths, and defines 143 schemas. It is described by OpenAPI 3.0.3, at version latest.
Requests are made against a single base URL, https://app.run.ai.
