One API key for GPT, Claude, Gemini & Seedance. OpenAI-compatible. Automatic failover. 99.99% uptime.
FuturMix is a unified AI gateway that gives every team — from solo developers to enterprises — reliable, secure access to the world's best AI models through a single endpoint. No vendor lock-in. No downtime. No complexity.
Why teams choose FuturMix over calling providers directly (or using OpenRouter):
- 22 models, one API key — GPT-5.4, Claude Opus 4.7, Gemini 3.1 Pro, Seedance 2.0, and more
- 20-30% lower cost than OpenRouter, with transparent per-model pricing
- 99.99% SLA with automatic failover — if one provider goes down, your app doesn't
- Zero data retention — we never log, store, or train on your prompts
- OpenAI-compatible — migrate in 2 lines of code

FuturMix works with any OpenAI-compatible tool or framework. It also supports the Anthropic Messages API format natively. Change one config value — nothing else.

"openai.baseURL": "https://futurmix.ai/v1",

}FuturMix supports the Anthropic /v1/messages format natively, so you can use it as a third-party inference provider in Claude Desktop:
- Open Claude Desktop → Help → Troubleshooting → Enable Developer Mode
- Go to Developer → Configure third-party inference
- Set:
- Base URL:
https://futurmix.ai - API Key: Your FuturMix API key
- Base URL:
- Select a Claude model and start chatting
Note: Use
https://futurmix.ai(without/v1) as the base URL — Claude Desktop appends/v1automatically. Authentication uses Bearer token format.
Set your API base to https://futurmix.ai/v1 in Cline settings. Choose "OpenAI Compatible" as the provider, enter your FuturMix API key, and select any model.
Same as Cline — set provider to "OpenAI Compatible", base URL to https://futurmix.ai/v1, and enter your API key.
