The core shape

  1. Read GET /v1/training/capabilities.
  2. Create a provider-routed session.
  3. Create one LoRA run on that session.
  4. Submit ordered training and sampler primitives.
  5. Poll each durable operation until terminal.
  6. Save resume state or export a LoRA adapter, then finish and close.
Use provider: auto unless you need deterministic provider routing. Every provider and model returned by capabilities is admitted for the operations it advertises.

Make your first request

Create a session and LoRA run with a Whitney API key.

Give this to a coding agent

Point an agent at Whitney’s MCP server or installable skill.
Do not put API keys, customer data, private checkpoints, or training payloads in a URL or documentation feedback form.
