OrcaRouter
One OpenAI-compatible AI gateway for production AI with adaptive routing, load balancing, guardrails, agent firewall, observability and governance across 200+ models
An AI gateway that routes requests across 200+ models with zero token markup, automatic failover, guardrails and compliance enforcement.
Overview

A look at orcarouter.ai
OrcaRouter is a production AI gateway that sits between applications and multiple AI models, intelligently routing each request to the model best suited to answer it at the lowest cost. The platform supports over 200 models through a single OpenAI-compatible endpoint with zero token markup, meaning users pay exactly what upstream providers charge.
The gateway includes adaptive routing that learns from traffic patterns to optimize the quality-cost trade-off, automatic failover to ensure reliability, and built-in observability that logs every call with its grade, model choice, latency and cost. Data privacy is protected by default—prompts are not logged unless explicitly enabled, with optional quantum-safe encryption for stored logs.
For teams and enterprises, OrcaRouter provides guardrails to block PII and policy violations before billing occurs, an agent firewall that gates tool and MCP calls, and compliance packs mapped to 32 regulatory frameworks. The platform is designed to integrate seamlessly into existing codebases with just a one-line change to point SDKs at the OrcaRouter endpoint.

FAQ
- Do you store or train on my prompts?
- OrcaRouter never trains on user prompts. Prompt and response bodies are not logged by default unless logging is enabled for the workspace. The platform keeps only request metadata such as time, model, tokens, cost and IP for billing and security purposes. Users can sign a zero-retention agreement to lock body logging off entirely.
- What is an AI router?
- An AI router is a system that sits between an application and multiple AI models, selecting the best model for each request. OrcaRouter grades every prompt in under 1 millisecond and routes requests across 200+ models at zero token markup, choosing frontier models for complex reasoning and open-source models for routine tasks.
- What is an LLM router and how does it work?
- An LLM router classifies each prompt and matches it to the model most likely to provide a good answer at the lowest cost. OrcaRouter uses contextual embeddings with online learning from live traffic to perform this routing, achieving 75.5% accuracy on the public RouterArena leaderboard.
- Is OrcaRouter an AI gateway?
- Yes, OrcaRouter is a production AI gateway providing one OpenAI-compatible endpoint with adaptive routing, load balancing, automatic failover, guardrails, an agent firewall, prompt caching and per-request observability.
- Does OrcaRouter mark up token prices?
- No. OrcaRouter adds zero markup on tokens. Users pay each provider's published rate, and OrcaRouter monetizes through optional Team and Enterprise subscription features rather than per-token margins.
