OpenRouter

OpenRouter is a unified API over many LLM providers. openrouter.ai/pricing still lists a Free row (25+ free models, 4 free providers) and Enterprise. BYOK has a fee-free allowance of $25,000 / month list-price inference on pay-as-you-go and $200,000 / month on Enterprise, then 5% of the equivalent OpenRouter price. Free-model rate limits in the FAQ source are 50 requests/day with no credits and 1,000 / day once you have at least $10 in credits. Model IDs change; do not freeze GPT-4o / DALL-E as the catalog.

Compare Ollama if you wanted a local runner plus Ollama's own cloud, and LangChain if you only needed a client library.

Key Features

• One key, many providers: The product is routing and failover, not a single vendor model.
• Credits wallet: You deposit, then burn per-model token (and sometimes per-request / image / reasoning) prices shown on each model card.
• BYOK: Use your own provider keys after the monthly free allowance. The 5% overage is deducted from OpenRouter credits.
• Free tier: Limited free models. It is not unlimited GPT-4o.

Use Cases

• Teams that want one invoice across Anthropic, OpenAI, Google, and others.
• People who will BYOK after they pass $25k / month list price.
• People comparing OpenRouter vs Ollama on router vs local runner.

Limitation: We did not re-verify every model dollar on the marketplace. Quote the live model card. Domain rating 142 is leftover catalog metadata, not a new audit.

Pricing

openrouter.ai/pricing and FAQ on 2026-08-17.

If a leftover blog still lists only GPT-4o / Claude / Gemini / DALL-E with no fee, treat this table as the source.

Getting Started

1. Create an account at openrouter.ai and read one live model card before you buy credits.
2. Add credits on the Credits page if you need paid models.
3. Confirm BYOK only after you understand the $25k / 5% line.
4. Compare Ollama if you wanted weights on your own GPU.

Frequently Asked Questions

Does OpenRouter mark up tokens?

FAQ says no markup on provider inference. The fee is on credit purchase and on BYOK overage.

Is there a $20 Pro seat?

Billing is credits plus optional Enterprise.

Same as LangChain?

No. LangChain is a client framework. OpenRouter is an HTTP router and wallet.

Alternatives

• Ollama: Local runner plus Ollama cloud seats.
• LangChain: OSS agent library.

Tips

1. Quote 5.5% Stripe and $25k BYOK, not "no fees."
2. Do not paste GPT-4o as the current catalog.
3. Confirm the live model card before you put a dollar in a contract.
