RunInfra does two things. You call a model we already host over an OpenAI-compatible HTTP API, or you hand us a Hugging Face model in the chat and we optimize it for you. One account does both, on one balance.

Call a hosted model

Set the base URL to https://api.runinfra.ai/v1, use a workspace API key, and pass a model id. There is nothing to provision.
Five models are hosted: deepseek-v4-flash, deepseek-v4-pro, qwen3-8-27b, qwen3-8-2-4t-a95b, and nemotron-3-5-lightning-30b. GET /v1/models is the authoritative list, and it reports when one is temporarily paused, which this page cannot.

Model APIs quickstart

Key, base URL, first call.

OpenAI compatibility

LangChain, LiteLLM, LlamaIndex, AI SDK, plain fetch.

Limits

Context, output budget, concurrency, tokens per minute.

Optimize your own model

Name a Hugging Face model in the chat, say what you want done with it, and the agent plans the work, prices it, measures candidates on real GPUs, and hands you the winner. The interface is the conversation, not a config file, so the request is a sentence:
Only the model is required. Leave the rest out and the agent asks before it acts, and no run starts until you accept its quote.

Run your first optimization

Fund, describe, run, keep the winner.

What accepting a plan locks

The accept boundary, and how to change your mind.

After the run

An endpoint you call, or a kit you run yourself.

Money, keys, and when it breaks

Pricing and credits

One balance, $10 minimum top-up, no subscription.

Account and access

Sign up, keys, workspaces, deletion.
