openapi: 3.1.0

  title: Whitney Training API
  version: 0.3.0
  description: >
    Public HTTP API for caller-owned model training on Whitney.


    Authenticate with a Whitney API key (`whitney_test_…` or `whitney_live_…`).

    Create a session and run, submit ordered training and sampling primitives,

    poll durable operations, and retrieve checkpoints, artifacts, usage, and
    cost.


    Every public request uses typed JSON. Token IDs and dense tensor values are

    ordinary JSON arrays validated against strict, provider-neutral schemas.
