Hostnot Gpu is cloud computing software providing on-demand GPU resources for AI, development, and high-performance computing. It features a unified workspace displaying live GPU capacity across regions, enabling selection based on memory, region, and configuration needs. GPU instances offer persistent environments with secure shell access for custom setups, model tuning, rendering, and experimental tasks. Serverless inference operates via an API supporting chat, image, and video workflows, with model discovery and validation integrated into the framework. Wallet-first authorization ensures rate review before deploying resources, while templates create repeatable environments for specific workloads. The developer API manages capacity and usage with scoped credentials and idempotency keys. Secure shell connections use verified public keys, with private keys stored on user devices. Dynamic rate calculation adjusts availability and pricing as infrastructure capacity changes.
