Free Models Router — Free API

What is Free Models Router?

OpenRouter Free Models Router dynamically selects from 25 free models at random, smartly filtering for models that support the features needed for each request — image understanding, tool calling, and structured outputs. Rather than locking into a single model, it routes to the best available free model at request time. 200K context window. OpenAI-compatible via OpenRouter. Free tier: 200 RPD (or 1,000 with $10 lifetime credit).
