OpenRouter
Models published by OpenRouter, available through the AnyRouter API. Each can route across multiple upstream providers for availability and price.
The simplest way to get free inference. This router selects free models at random from those available on OpenRouter, intelligently filtering for features like image understanding, tool calling, and structured outputs. Available through OpenRouter with a user-owned API key (BYOK). Note: You must configure your own OpenRouter API key in the dashboard to use this model.
Fusion turns a prompt into a small multi-model deliberation. A panel of expert models (Quality preset: Claude Opus, GPT, and Gemini Pro; Budget preset: Gemini Flash, DeepSeek V3.2, and Kimi) analyzes the prompt in parallel with web search and web fetch enabled, then a judge model synthesizes their responses into a structured analysis — consensus, contradictions, partial coverage, unique insights, and blind spots — and writes the final answer. Reach for it when a single model isn't enough: research, expert critique, or anywhere the cost of being wrong outweighs a few extra completions. Because every panel member plus a judge call runs, the request is priced as the sum of those underlying completions. Available with a user-owned API key (BYOK).
