Prices are per 1M tokens, in USD. Cache = re-read cached context, billed far cheaper. Billed to your Klef balance — no per-provider subscriptions.

Klef AI isn't a model of ours — it reads your request, picks the models best suited to it and combines them into one answer. You pay the rates above for whatever it ran, plus a few hundredths of a cent for the pass that chose them. Nothing on top.

The road ahead

Where Klef is headed — from launch to the full ecosystem.

01

Launch

Klef goes live alongside the $KLEF token. One key, every major AI model, crypto-native from day one.

02

Grow & strengthen

Continuous updates, more models, and deeper $KLEF utility — token holders get better pricing and access as the platform expands.

03

Built for everyone

Not just for developers. A simple, beautiful chat experience so anyone can talk to any AI model inside Klef — no setup, no code, no learning curve.

04

Klef everywhere

Native apps for desktop and mobile. Take Klef with you and use any model wherever you are, on any device.

05

The full ecosystem

Team accounts, analytics, custom routing, and new ways to spend $KLEF — Klef becomes the default gateway to AI, for builders and everyday users alike.

Common questions

1What is Klef?+

Klef is a single API key that unlocks every major AI model — Claude, GPT, Gemini, Llama and more. Use it in the tools you already work with, or chat with any model right inside Klef.

2How do I pay?+

You top up your balance with SOL or the $KLEF token — no cards, no subscriptions. Paying with $KLEF gets you the best rates across every model.

3Do I need to be a developer?+

Not at all. Developers can drop their key into Claude Code, Codex, Cursor and more, while everyone else can simply chat with any model directly inside Klef — no setup or code required.

4Why is Klef cheaper than going direct?+

One key routes you to every provider through a single balance, so you skip five separate subscriptions and pay only for what you use — at a fraction of the usual cost.

5Which models can I access?+

All the major ones — Claude, GPT, Gemini and more, with new models added as they launch. One key always stays up to date.
