Why FastInfra

Built to win at scale

Stop juggling provider accounts, SDKs, and pricing spreadsheets. FastInfra gives your team one production API for serverless models and dedicated GPU pods — the breadth of OpenRouter plus bare-metal compute when you need it.

One integration, every model

Swap models with a single parameter. GPT, Claude, Llama, Gemini, DeepSeek — all through the same OpenAI-compatible endpoint your team already uses.

Intelligent cost routing

Our routing layer automatically selects the lowest-cost upstream path per model, so you ship faster without leaving margin on the table.

Enterprise from day one

Rate limits, API keys, usage tracking, and transparent per-token pricing — everything you need to move from prototype to production.

On-demand GPU pods

Deploy RTX 4090, A100, H100, H200 and more with any Docker image. Per-minute billing from prepaid credits — stop the pod and the meter stops.

How it works

Live in three steps

From signup to first production request in minutes, not weeks.

Step 01

Create your account

Sign up free and generate an API key from your dashboard. No credit card required to start building.

Step 02

Point your SDK at FastInfra

Use any OpenAI-compatible client. Change the base URL and API key — your existing code keeps working.

Step 03

Ship to production

Route across 811+ models with automatic failover, streaming, and pay-per-token billing — or spin up a GPU pod for training, fine-tuning, and custom stacks.

GPU Cloud

Dedicated GPUs, billed per minute

Need bare metal for training, fine-tuning, ComfyUI, vLLM, or Jupyter? Browse 47+ GPU tiers, pick a Docker image, and deploy in seconds — no long-term contracts.

Any Docker image

Bring your own stack — custom env vars, exposed ports, and persistent volumes when you need them.

RTX 4090 to H200

Secure and value tiers across consumer and datacenter GPUs. Scale from a single GPU up to multi-GPU pods.

Stop = stop billing

Prepaid wallet billing by the minute while a pod runs. Stop or terminate anytime — no surprise invoices.

Same account, one wallet

API inference and GPU pods share your FastInfra balance. One dashboard for keys, usage, and pod management.
