what happens if I use my API key from open router to odyseus AI? will it charge me

Using your OpenRouter API key with Odysseus AI will not charge you anything on Odysseus itself, but it will use your OpenRouter credits and can charge you via OpenRouter depending on how you route requests and what models you call.

Quick answer

  • Odysseus AI : No extra fee just for adding an OpenRouter key. Odysseus is a client that forwards your requests to the provider you choose (OpenRouter, OpenAI, Anthropic, etc.).
  • OpenRouter : Yes, you can be charged if:
    • You use paid models via OpenRouter (costs are deducted from your OpenRouter credits or billed according to your plan).
* You use **BYOK mode** (your own provider key) and pass more than 1M requests/month through OpenRouter (then a 5% fee is added on top of the provider’s cost).
  • If you only use free models on OpenRouter and stay within their limits, you usually won’t see a charge, but you still “consume” your free-tier allowances.

What actually happens when you add the key

  1. In Odysseus
    You go to:

    • Settings → AI Model → API → choose OpenRouter → paste your key → Save.

This just tells Odysseus: “Send my requests to OpenRouter using this key.”

  1. When you send a message
    • Odysseus sends your prompt to https://openrouter.ai/api/v1/... with your OpenRouter key as the Authorization header.
    • OpenRouter routes the request to the model provider (e.g., Claude, GPT, etc.).
    • The provider charges per token; OpenRouter deducts that from your OpenRouter credits or bills you.
 * Odysseus does **not** add its own charge for this forwarding.

“Use Odysseus AI with cloud/API models when local hardware is weak. Configure OpenRouter, OpenAI-compatible endpoints, privacy, costs, and fallbacks.”

Will it charge you?

It depends on three things:

1. Which models you call

  • Paid models (e.g., anthropic/claude-3.5-sonnet, openai/gpt-4o, etc.):
    • You will be charged via OpenRouter according to the provider’s per-token rates.
    • Costs are deducted from your OpenRouter balance or billed.
  • Free models (marked free on OpenRouter):
    • No direct charge, but you have:
      • Per-minute limits,
      • Daily limits that depend on how many credits you’ve bought.

2. How you use OpenRouter (regular key vs BYOK)

  • Regular OpenRouter key (your OpenRouter account, not your own provider key):
    • You pay the provider’s exact rates.
    • Plus OpenRouter’s platform fee (commonly ~5.5% on pay-as-you-go).
  • BYOK mode (you register your own OpenAI/Anthropic key inside OpenRouter):
    • First 1M requests/month: no extra OpenRouter fee.
    • Above 1M: +5% on top of the provider cost, still deducted from your OpenRouter credits.

If you’re just using your OpenRouter key directly in Odysseus (not BYOK), you’re in the first case.

3. Your OpenRouter balance and limits

  • OpenRouter is not a flat monthly subscription; it’s prepaid credits + pay-as-you-go.
  • If your balance goes negative or you hit a limit, requests will fail with a 402 Payment Required error until you top up.
  • Just creating an account and an API key is free; charges only start when you actually call models.

Practical tips to avoid surprise charges

  • Check your model selection in Odysseus :
    • If you choose a clearly paid model (e.g., Claude 3.5, GPT-4o), you will incur OpenRouter charges.
    • If you want “free” testing, explicitly pick a free model from OpenRouter and stay under its limits.
  • Set a credit limit on your OpenRouter key :
    • OpenRouter allows you to set a credit limit per API key so external apps can’t exceed it.
  • Monitor usage on OpenRouter :
    • Use the OpenRouter dashboard to see token usage and costs per key/model.
  • Don’t share your key :
    • If someone else gets your OpenRouter key, they can use it and your credits/balance.

Summary

  • Adding your OpenRouter API key in Odysseus AI is free and does not create a new charge from Odysseus.
  • You can be charged if:
    • You call paid models via OpenRouter, or
    • You use BYOK and exceed 1M requests/month.
  • If you only use free models and stay within limits, you typically won’t see a direct charge, but you still consume your free-tier allowances.
