Nscale

Nscale is an AI/GPU cloud that pairs serverless, OpenAI-compatible inference with on-demand GPU compute. The Serverless Inference API serves open models (Llama, Qwen, DeepSeek, GPT OSS, Mistral, Flux) at https://inference.api.nscale.com/v1 with pay-per-token billing, while the platform API provisions GPU clusters, compute instances, networks, and storage.

Nscale publishes 5 APIs on the APIs.io network, including Chat API, Completions API, Embeddings API, and 2 more. Tagged areas include AI, GPU, Inference, Serverless, and Cloud Compute.

The Nscale catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

Nscale’s developer surface includes authentication, engineering blog, documentation, and 7 more developer resources.
