Your API Keys. Your Models. Your Cost.
AI-Flow is built around BYOK. Connect your Anthropic, OpenAI, Replicate, or Google keys and pay providers directly — no platform markup, no subscription.
Every hosted AI tool adds a layer between you and the model provider. You pay their markup on every run. You're locked into their model selection. You have no visibility into actual costs. AI-Flow removes that layer entirely.
How BYOK works in AI-Flow
Add your key once
Store it in Settings → Secure Store. Encrypted, never exposed in outputs or logs.
Every node uses it automatically
No per-node configuration. Every workflow picks up your key without any extra setup.
Pay the provider directly
You pay Anthropic, OpenAI, or Replicate at their rate. AI-Flow charges a small one-time platform fee — never a percentage of your model costs.
Supported providers
Every provider below works with your own key. New models are added as providers release them.

- One-time credit purchase for platform features, no recurring fee
Build something real
A few workflows that make sense for someone with their own keys.
LLM Pipeline
Chain Claude and GPT in a single workflow. Use Claude for reasoning, GPT for structured output — each node uses its own provider key.
Image + Video Pipeline
Generate an image with Flux on Replicate, animate it with Kling, upscale the result — all in one canvas, all at provider cost.
Data Extraction API
Build a structured data extraction pipeline with GPT Structured Output, expose it as a REST endpoint. Your OpenAI key, your cost, your API.

Browse real workflow examples built with BYOK — image generation, video pipelines, LLM chains, and more. Each one runs on your own provider keys.
Frequently Asked Questions
Is my API key secure?
Keys are stored encrypted in AI-Flow's secure store and never exposed in workflow outputs or logs.
Do I still need to buy AI-Flow credits?
AI-Flow charges a small one-time platform fee for features like media storage, parallel execution, and API exposure. Model costs go directly to your provider.
What if I only have one API key?
That's fine. You can use AI-Flow with a single provider and add others later. The free tier works immediately with your own keys.
Can I mix BYOK and platform credits?
Yes. Some nodes can use your keys, others can use platform credits in the same workflow.
You already pay for API access. AI-Flow is the canvas that puts it to work.
