Practical Hostnot GPU guides for GPU cloud compute, SSH access, APIs, serverless inference, billing, security, and troubleshooting.

Quickstart

Create an account, fund a wallet, add an SSH key, and launch compatible capacity.

API Reference

Authentication, production base URLs, pagination, errors, idempotency, and customer API examples.

API Examples

Equivalent cURL, PowerShell, Python, and JavaScript request patterns using placeholder credentials.

GPU Cloud

Understand Hostnot GPU cloud instances, live capacity, GPU selection, wallet authorization, SSH access, and lifecycle operations.

Public GPU Availability API

Poll current Hostnot GPU availability and customer-facing hourly prices without an API key.

SSH Connections and Fingerprints

Connect safely to a Hostnot GPU instance from Linux, macOS, or Windows.

Serverless API

Model discovery, inference requests, usage, pricing, errors, and safe client patterns.

Models

Browse current Hostnot GPU serverless models, modalities, limits, request patterns, and how to verify live model capabilities.

Billing and Wallet

Deposits, reservations, GPU usage, serverless usage, and transactions.

Developer Security

Secure Hostnot GPU API and serverless integrations with scoped keys, safe logs, rate limits, validation, and credential hygiene.

API Keys

Create scoped keys, store them safely, and revoke them after suspected exposure.

Deploying and Managing GPU Instances

Choose a compatible offering, authorize deployment, connect with SSH, and terminate when work is complete.

Organizations and Workspaces

Create a shared workspace, invite members, manage roles, and understand workspace boundaries.

Support and Human Handoff

Use AI Support for guidance and request a human handoff when an operator needs to take ownership.

Account Security and Two-Factor Authentication

Protect sessions, passwords, two-factor authentication, connected accounts, and notification preferences.

Usage, Transactions, and Budgets

Read GPU and Serverless usage, understand settlement, and set account budget safeguards.

Serverless Quickstart

Make a first authenticated Serverless request using a live model slug.

Serverless Errors and Rate Limits

Interpret structured Serverless errors and retry without duplicating work.

Serverless Playground

Use the authenticated Playground to test available chat and image capabilities.

GPU Marketplace

Compare live GPU offerings, topology, regions, environments, and customer rates.

GPU Cloud Troubleshooting

Diagnose Hostnot GPU SSH, GPU driver, Docker, CUDA, instance, serverless, and billing issues with safe evidence-first steps.

Webhooks

Configure Hostnot GPU webhooks, verify signed deliveries, handle retries, and inspect customer-safe event payloads.

Wallet Deposits

Understand Hostnot GPU wallet deposits, payment confirmation, reservations, credits, and safe billing verification steps.

Billing History

Read Hostnot GPU billing history, wallet-period summaries, usage categories, and account-scoped transaction records.

PowerShell API Examples

Use Invoke-RestMethod from PowerShell without exposing API keys in command history.

Define the workload before renting compute

Dedicated GPU compute gives you an environment to run your own software. Determine the exact model or dataset, framework version, peak device memory, CPU/RAM, disk requirements and access method first. GPU count means devices within one machine; it is not a distributed cluster or proof of a particular interconnect. Use the memory worksheet and Marketplace selection to prepare a shortlist.

Review an exact offering and authorization

Compare current GPU variant, count, memory, region, capacity class, CPU, RAM, storage and compatible environment. The public directory groups comparison rows; API deployment requires a current authenticated offering ID. A displayed rate and future availability are not guaranteed by an earlier screenshot.

Review the selected customer rate separately from the maximum authorized rate. API automation uses an explicit quote intent before launching the reviewed configuration and ceiling; omitted intent defaults to launch. A changed ceiling requires a fresh review rather than silently increasing it. Read quote and launch fields. An accepted launch is not proof of readiness.

Verify the delivered environment

  1. Wait for readiness and use the assigned host, user and port from the workspace.
  2. Verify the server fingerprint through the trusted workspace before accepting the SSH connection. Upload only your public key.
  3. Inspect the allocated devices, memory, framework and disk. Run a small application-level check before a full job; NVIDIA SMI alone does not verify CUDA arithmetic.
  4. Keep development listeners on loopback and use SSH forwarding. Confirm storage behavior before relying on local checkpoints.

Use the connection checklist and a bounded tensor test. A root shell inside a container is not permission to replace the host driver. Escalate managed-host failures instead of applying blanket driver, firmware or Docker changes.

Operate and finish deliberately

Bound job duration, retries and checkpoint intervals. Record instance ID and UTC times so usage windows can be matched to work. Before termination, export needed outputs and verify that they can be read from their destination. Do not assume every disk persists after termination or that an idle process triggers automatic shutdown.

Use the supported instance termination control and confirm resulting status. Closing SSH or stopping a notebook does not terminate the allocation. Reservations differ from completed charges; reconcile usage and wallet records without counting both as separate expenses. See instance controls and billing.

When to use another path

If you only need a supported model request, compare serverless inference before taking on driver, runtime, service security and storage ownership. Dedicated compute is appropriate when your requirements justify that work, not automatically faster or cheaper for every task.
