Serverless Inference
Run text, vision, image, video, embedding, and reranking models on managed OpenAI-compatible endpoints.
Serverless Inference gives you managed endpoints for state-of-the-art models — no GPUs to provision, no weights to load, no scaling to manage. Sign in, create a key, and call the API.
The endpoint is OpenAI-compatible and lives at https://inference.nebulablock.com/v1, so any OpenAI SDK or tool works by changing the base URL.
What you can do
Chat and text generation, including tool use and streaming
Send images to a model and ask about them
Generate and edit images
Generate video from text or an image
Turn text into vectors for search and RAG
Reorder retrieved documents by relevance
The Model Catalog lists every model currently served, grouped by what it does.
Prerequisites
An API key
Credit on your account — most models are capped at 0 requests per day on Tier 1, so a $5 deposit (Tier 2) is what opens up the catalog. See Tiers and Rate Limits.
Key features
OpenAI compatible. Point the OpenAI Python, Node, or any compatible client at the base URL above.
One key, every modality. Text, vision, image, video, embedding, and reranking models share the same authentication and the same base URL.
Pay as you go. Billed on usage, metered per token — or per image or per second for some media models. See the pricing page.
Try before you integrate. Every model has a playground in the console under Serverless.
Canadian-hosted options. Models marked 🇨🇦 in the catalog run in Canada for data-residency requirements.
Rate limits
Two limits apply to every call: your account-wide rate limit (RPM, TPM, RPD) and a per-model daily cap that varies by tier. Both are documented in Tiers and Rate Limits, and your account's current numbers are shown under Limits in the console.
