Started as
a personal tool

In 2024, one of us simply wanted to work normally with ChatGPT. No constant disconnects, no "service unavailable", no solutions that slow down the connection. We built it for ourselves — then started sharing it with colleagues. Now it's AIFast.

We don't buy ready-made solutions or resell someone else's infrastructure. Everything is ours: servers, configs, monitoring. That means when something changes on the network, we see it ourselves and respond ourselves — usually before users even notice.

We use modern transport protocols over TLS — the connection looks like an ordinary HTTPS request to major international services. That's why AIFast stays stable where other services fail.

On top of that — an API proxy to language models. One endpoint, one auth key, direct model access. Works for personal use in any client and for code integration.

VLESS + REALITY XHTTP Transport Hysteria2 TLS 1.3 + XTLS OpenAI-compatible API no logs

No traffic logs

We don't know and don't want to know what you're browsing. Technically not stored.

Works on first try

Setup through the bot — one button, ready config. No 40-page instructions.

Live support

Not a bot. A real person — we usually respond within an hour.

TLS 1.3 + XTLS REALITY

Modern transport protocols with encryption and real TLS 1.3 certificates.

All devices

iOS, Android, Windows, macOS, Linux — and routers. Configs for every platform.

OpenAI API-compatible

Change base_url — everything else works as before. GPT-4o, Claude 3.5, Gemini 2.0.

  1. Launched for ourselves

    Set up a server, wrote a simple config. Shared with friends. It worked — already better than anything else available.

  2. First paid subscriptions

    Requests started coming from strangers. We built a bot, added payments, wrote proper instructions.

  3. Next-gen protocol migration

    The network landscape changed — we migrated to VLESS+REALITY and XHTTP Transport. Stability improved significantly.

  4. AI API and automation

    Added proxy to language models. Rebuilt the management panel, automated most operations.
