Which one, for what

Hyperbolic D

Good for Agents that rent whole H100, H200 or B200 machines or multi-node clusters for training and batch work and that have a funded account.

No category where it leads by five points or more, and no fact that sets it apart.

Watch for

API keys carry no scopes or expiry in the reviewed documentation, and the same key can call DELETE /v2/users/me

Vast.ai B

Good for Cost-sensitive training, batch work and self-managed inference where the agent can search listings, set a price cap and tolerate host variance or interruption.

Ahead on

  • Reliability, 65 against 52
  • Security & auth, 72 against 47
  • Payments & pricing, 20 against 15
  • Maintenance & community, 81 against 42

Also in its favour

  • No incidents deducted, where Hyperbolic loses 3 points for them

Watch for

No SLA. The terms say availability is not guaranteed and the service can change without notice

Verdicts

Hyperbolic

The API serves its own OpenAPI 3.1 document without a key, lists GPU prices on an open endpoint and dates the removal of legacy paths at 1 March 2027. API keys carry no scopes and can delete the account, rental creation has no idempotency key, and renting needs a browser signup and a $5 deposit.

Vast.ai

API keys can be limited by permission category and by resource ID, the REST API has a public OpenAPI 3.1 file, and the CLI ships weekly with a skill file for coding agents. Machines belong to independent hosts, prices move with the market, rate-limit thresholds are unpublished, and there is no SLA or free tier.

Before you call either

Hyperbolic

  1. Read GET /v2/on-demand/rental-options first. It needs no key and lists what can be rented now, with costPerHourCents per GPU configuration.
  2. Send rentalType and gpuCount to POST /v2/on-demand/rentals. Region defaults to us-central-1 and GPU type to h100, so set both from the options list.
  3. List active rentals before retrying a failed create call. There is no idempotency key and every ready rental bills hourly.
  4. Save an SSH public key with POST /v2/ssh-keys before renting. Without sshPublicKeyIds the newest saved key is attached.
  5. Do not create reserved rentals unless asked. They are paid in full up front and cannot be terminated early.

Vast.ai

  1. Create a scoped key with vastai create api-key --permissions for the agent. A default key has full account access, billing and key management included
  2. Pass --raw on every CLI command for JSON output, and -y on vastai destroy instance, which otherwise waits for a confirmation prompt
  3. Register an SSH key with vastai create ssh-key before creating an instance, or the host is unreachable
  4. Destroy instances when finished. A stopped instance still bills storage, and a zero balance without a saved card leads to deletion
  5. Back off on HTTP 429 yourself when calling REST directly. The CLI retries 429 three times from 0.15 seconds
  6. Filter searches with verified=true or the Secure Cloud option for sensitive data, and set a dph_total price cap

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
