The AI inference platform.
One API, GPU cloud & bare metal.
Ship AI products faster with a single OpenAI-compatible API and on-demand GPU pods. 785+ models, 49+ GPU tiers, intelligent routing, transparent pricing — built for teams that scale.
FastInfra is an AI inference platform that puts hundreds of language, vision, video and speech models behind one OpenAI-compatible API, with automatic lowest-cost routing and transparent per-token prices. The same account rents GPU pods billed by the minute, Linux CPU servers and dedicated bare-metal machines, so a team can prototype on the free tier, scale on the API and move heavy workloads onto its own hardware without changing vendors.

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 — hundreds of frontier models 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.
Live in three steps
From signup to first production request in minutes, not weeks.
Create your account
Sign up free and generate an API key from your dashboard. No credit card required to start building.
Point your SDK at FastInfra
Use any OpenAI-compatible client. Change the base URL and API key — your existing code keeps working.
Ship to production
Route across 785+ models with automatic failover, streaming, and pay-per-token billing — or spin up a GPU pod for training, fine-tuning, and custom stacks.
Dedicated GPUs, billed per minute
Need bare metal for training, fine-tuning, ComfyUI, vLLM, or Jupyter? Browse 49+ 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.

What is FastInfra?
FastInfra is an AI inference platform. It exposes hundreds of models through one OpenAI-compatible API with automatic lowest-cost routing, and it rents GPU pods, CPU virtual servers and dedicated bare-metal servers from the same account.
Is FastInfra compatible with the OpenAI SDK?
Yes. Keep the official OpenAI SDK, change base_url to the FastInfra API host and use a FastInfra API key. Chat completions, streaming, tool calling, embeddings and model listing use the same request and response shapes.
Does FastInfra have a free tier?
Yes. A set of chat models is available at $0 per token with published rate limits. Paid models bill per token from prepaid credits with no subscription or monthly minimum.
How is GPU cloud billed on FastInfra?
GPU pods bill per minute while they exist, with hourly and monthly estimates shown in the public configurator before you deploy. Attached volumes bill per GB-month, including while a pod is stopped.
Which infrastructure products does FastInfra offer?
Four: the inference API (pay per token), GPU Cloud (RTX 4090 to H200 pods by the minute), CPU Cloud (Linux virtual servers by the minute) and Dedicated Servers (bare-metal EX, AX, RX, SX and GPU lines plus auction stock).
