# Stop Alignment

> Stop an in-progress alignment training job.

**Path Parameters:**
- `alignment_id`: Alignment project identifier

**Returns:**
- `alignment_id`: ID of the stopped alignment project
- `status`: New status

**Raises:**
- `400`: If the alignment is already in a terminal state or has no training job yet
- `404`: If the alignment project is not found or does not belong to the user
- `502`: If the training cluster rejected the stop request
- `503`: If the training cluster is unreachable

    **Need an API key?** Sign up, log in to the platform and generate an API
    key.


    **Need help?** Sign up, log in to the platform and raise a support ticket.


    **What this API does.** Align models to your domain corpus and run them with

    confidence. Train-time alignment builds domain-aligned adaptors through

    proprietary methods spanning pre-training, supervised and reinforcement

    stages. Inference-time alignment quantifies uncertainty across the full

    generation trajectory, producing confidence scores and keeping every

    response on domain.


    **Workflow.** Upload documents, create or generate a benchmark, create an

    alignment project, receive an aligned model id. That one id serves chat

    completions, completions, embeddings and reranking, and its embeddings carry

    your domain's representation space, making retrieval domain aware. You
    define the success

    criteria for your domain; the platform handles the deep learning, the GPUs

    and the data preparation.


    **Authentication.** Every endpoint requires an API key sent as a Bearer
    token:

    `Authorization: Bearer <api_key>`.
