Pricing Model
Dynamic Passthrough Pricing
OpenRouter uses passthrough pricing where you pay the vendor’s cost plus OpenRouter fee, then Splox platform fee.Pricing Formula:
Final Price = (Vendor Cost + OpenRouter Fee) + Splox Platform FeePricing updates automatically when vendors change rates.How It Works
- Select a model (e.g.,
openai/gpt-4,anthropic/claude-3-opus) - OpenRouter routes your request to the vendor
- You’re charged vendor cost + OpenRouter fee + Splox fee
- Pricing updates automatically in real-time
Example Pricing
Approximate costs (vendor + OpenRouter + Splox fees):| Provider | Model | Input | Output |
|---|---|---|---|
| OpenAI | GPT-4o | ~$3.25/M | ~$13.00/M |
| Anthropic | Claude Opus 4.1 | ~$19.50/M | ~$97.50/M |
