# List GPU types

> Available GPU models, per-data-center availability, and current list prices for the on-demand pool. Browsing does not reserve capacity; availability and price are rechecked at quote time. Requires compute `read` access.

  title: AI Reserve Gateway API
  description: >-
    The AI Reserve API surface — OpenAI-compatible chat completions,
    Anthropic-compatible messages, Bedrock Converse, images, video, files,
    text-to-speech, realtime voice sessions, and provider-hidden GPU
    infrastructure — all behind one endpoint and one API key.

    description: >-
      Per-end-customer usage, cost, and billable amounts for organizations that
      tag requests with their own customers.
  - name: GPU Infrastructure
    description: >-
      Provision and manage provider-hidden GPU instances. The recommended
      Instances API accepts workload requirements and an hourly price ceiling;
      AI Reserve handles provider placement internally. Every mutation is
      asynchronous and returns an operation to poll.
  - name: Customer keys
    description: >-
      Mint, list, and revoke API keys pinned to your own end customers (and
      their organizations), so spend splits per customer without per-request
      tagging.
