OpenRouter

Multi-provider LLM router

Free tier + paidModel APIs, routers & observabilityopenrouter.ai

What it is

A single OpenAI-compatible endpoint that fronts 500+ models from OpenAI, Anthropic, Google, Meta and dozens of inference hosts. It is a router, not a model provider — it resells other people's inference at list price and picks a backend by price, latency or uptime.

Why it earns a slot

One API key and one billing relationship for every model, so you can swap anthropic/claude-opus-5 for google/gemini-3.7-flash in a string and A/B the cost. Free models let you prototype at zero spend.

Know before you commit

Routing is opaque by default — the same model slug can land on providers with different quantization, context limits and data-retention policies. Pin providers explicitly for production.
