Listed rates are per 1M tokens as listed by each provider. FuturMix rates are sourced from our live pricing API. OpenRouter effective rate adds OpenRouter's 5.5% credit purchase fee to the provider's listed rate (OpenRouter applies 0% markup on inference). Prices reflect provider listed rates and FuturMix rates at the time of publication (last updated June 26, 2026); rates may change.

Real Cost: Why OpenRouter Is More Expensive Than It Looks

OpenRouter advertises "no per-token markup" — but that's only half the story. Every time you buy credits, you pay:

FuturMix charges zero platform fees. The discount is baked into the per-token rate — what you see is what you pay.

📈 Example: 100M tokens/month on Claude Sonnet 4
OpenRouter: $3.00/M × 100M = $300 + 5.5% fee = $316.50/month
FuturMix: $2.70/M × 100M = $270.00/month
Monthly savings: $46.50 (15%) — that's $558/year on input tokens alone.

Migrate from OpenRouter in 2 Minutes

FuturMix exposes OpenAI-compatible endpoints. Change the base URL and API key, and most existing code works immediately. Your OpenRouter token (the sk-or-v2- key) is simply replaced by your FuturMix key — no other code changes.

Python (OpenAI SDK)

from openai import OpenAI # Before (OpenRouter) — sk-or-v2- token client = OpenAI( base_url="https://openrouter.ai/api/v1", api_key="sk-or-v2-..." ) # After (FuturMix) — change 2 lines client = OpenAI( base_url="https://futurmix.ai/v1", api_key="sk-your-futurmix-key" ) # Everything else stays exactly the same response = client.chat.completions.create( model="claude-sonnet-4-6", messages=[{"role": "user", "content": "Hello"}] )

Environment Variables (Claude Code / Cursor / Aider)

# Before (OpenRouter) — sk-or-v2- token export OPENAI_API_BASE="https://openrouter.ai/api/v1" export OPENAI_API_KEY="sk-or-v2-..." # After (FuturMix) export OPENAI_API_BASE="https://futurmix.ai/v1" export OPENAI_API_KEY="sk-your-futurmix-key"

cURL

curl https://futurmix.ai/v1/chat/completions \ -H "Authorization: Bearer sk-your-futurmix-key" \ -H "Content-Type: application/json" \ -d '{ "model": "gpt-5.4", "messages": [{"role": "user", "content": "Hello"}] }'

Anthropic SDK (Native)

import anthropic # FuturMix also supports native Anthropic API format client = anthropic.Anthropic( base_url="https://futurmix.ai", api_key="sk-your-futurmix-key" ) message = client.messages.create( model="claude-opus-4-6", max_tokens=1024, messages=[{"role": "user", "content": "Hello"}] )

Credits you top up never expire and there is no credit-purchase fee, so the discount applies to every request without chasing coupon codes.
