OpenRouter is a unified AI gateway that routes API calls to 300+ models from OpenAI, Anthropic, Google, Meta, and 60+ other providers through one OpenAI-compatible endpoint. It passes through provider pricing with no inference markup and automatically fails over to the next available provider when one is down or rate-limited.
About OpenRouter
OpenRouter gives you one API endpoint to call AI models from OpenAI, Anthropic, Google, Meta, Mistral, and 60+ other providers. Instead of managing separate API keys and billing accounts for each, you fund a single OpenRouter balance and it handles routing; the API is compatible with OpenAI's format, so most existing code works without modification. Founded in 2023 by Alex Atallah (OpenSea co-founder), the company has raised $153M+ across several rounds, most recently a May 2026 Series B led by CapitalG/Alphabet at a roughly $1.3B valuation.
OpenRouter now serves 4.2M+ users across 250k+ apps, processing 30+ trillion tokens per month.
Pricing
0% flat), then spend per-token at provider rates with no inference markup. BYOK: first $25,000/month of equivalent inference value fee-free, 5% after. Enterprise: first $200,000/month fee-free threshold, 5% after, plus SSO/SAML, contractual SLAs, and dedicated support.
A free tier is also available with daily request caps (see the free-tier FAQ for limits).

| Enterprise | Custom | Custom volume pricing; first $200,000/month equivalent inference value fee-free, 5% after. Annual commits, prepaid invoicing, SSO/SAML, contractual SLAs, priority support. |
Key Features
- One Endpoint for Every Major Lab: A single OpenAI-compatible endpoint reaches frontier and open models across every major AI lab, so existing OpenAI SDK code typically works unchanged after swapping the base URL and key.
- Provider-Rate Pass-Through Billing: Usage bills at the same per-token rate the underlying provider charges, on a single consolidated invoice across every model instead of separate accounts per lab.
- Intelligent Model Routing and Fallback: Automatic routing optimized by cost, latency, and availability; multi-provider failover ensures 99.9%+ uptime if one provider goes down, with zero billing for failed attempts.
- Edge-Deployed Global Infrastructure: Cloudflare-powered edge deployment with ~25ms latency overhead; real-time performance metrics (TTFT, throughput) published for each provider per model to enable informed routing decisions.
- MCP Server for Coding Agents: Native MCP server (launched June 2026) gives coding agents live model rankings, pricing, benchmark scores, and test inference via OAuth-based setup with capped API keys and provider-aware model testing.
- Image API Across 30+ Models: Dedicated Image API (launched June 2026) with capability discovery across 30+ image generation models from 8 providers through a single endpoint, including metadata on what each model supports.
- Workspaces and Response Caching: Workspaces (May 2026) let teams organize projects into separate environments with their own settings, keys, and budgets; response caching cuts cost and latency for identical requests in agent workflows and testing.
- Enterprise Data Controls: Fine-grained provider selection, EU in-region routing via eu.openrouter.ai, SOC 2 Type 2 certification, and customer controls over data logging and training usage across all routed providers.
Pros
- Wide unified catalog of models across every major AI lab, from OpenAI and Anthropic to Meta and Mistral, through one API and one bill.
- True pricing transparency with zero inference markup; exact cost parity with provider direct pricing.
- Enterprise-grade reliability with multi-cloud automatic failover and zero-completion insurance.
- Low-latency edge infrastructure (~25ms overhead); publicly tracked latency/throughput per provider.
- Developer-friendly with OpenAI SDK compatibility, extensive integrations (LangChain, Vercel AI SDK, and others), and detailed documentation.
Cons
- Requires prepaying into a credit balance; card and crypto purchases both carry a purchase fee.
- BYOK (Bring Your Own Keys) usage above the monthly fee-free threshold incurs an extra charge.
- No SLA guarantees published for response times; latency depends on the routed provider.
- Complex routing configuration is available but default behavior may not optimize for all use cases.
Data Handling
- Compliance
- SOC 2 Type 2
Frequently Asked Questions
How much does OpenRouter cost in 2026?
OpenRouter passes through each provider's own per-token rate with no inference markup, so cost depends entirely on the model you call. Buying credits costs a 5.5% fee by card (5.0% flat by crypto), and BYOK usage stays fee-free up to $25,000 of equivalent inference value per month, then 5% after. Enterprise plans get a $200,000 monthly fee-free threshold plus SSO, contractual SLAs, and dedicated support.
Is OpenRouter free to use?
Yes: OpenRouter's free tier gives access to a rotating set of free models with no credit card required. Rate limits are 50 requests per day on those models (rising to 1,000 per day once you've purchased at least $10 in credits) and 20 requests per minute.
What should you use instead of OpenRouter?
CometAPI and AIML API are both unified AI gateways like OpenRouter, but each adds its own markup instead of passing through provider rates unchanged. Together AI fits better when you also need fine-tuning or dedicated GPU clusters, not just routed inference. Groq is worth considering if you only need its own hosted open-weight models at very low latency.
OpenRouter or CometAPI: which should you pick?
CometAPI prices each model roughly 20% below the official provider rate and lets unused credit balances carry over indefinitely, while OpenRouter passes through the provider's list price exactly, with no markup and no discount. CometAPI is the cheaper raw per-token option in most cases; OpenRouter is the safer pick if you want billing that always matches what the model's own maker charges.
How long does it take to get going with OpenRouter?
Sign up, grab an API key from the OpenRouter dashboard, and point your existing OpenAI SDK client at OpenRouter's base URL: most setups need no code rewrite. Pick a free model to test the integration, or add credits via card or crypto to try paid models. Most developers have a working call within a few minutes.
Top Alternatives
- CometAPI: Pick CometAPI if you want per-model pricing already discounted below official provider rates; pick OpenRouter for zero-markup pass-through pricing across a wider provider list.
- AIML API: Pick AIML API if a $20 minimum prepaid balance is fine; pick OpenRouter if you want to start on a free tier with no minimum purchase.
- Together AI: Pick Together AI if you need fine-tuning and dedicated GPU clusters alongside inference; pick OpenRouter if you only need unified inference routing across many providers.
- Groq: Pick Groq for the fastest raw inference on its own hosted open-weight models; pick OpenRouter for access to closed frontier models like GPT and Claude through the same unified API.
