Auto Router (Beta)

OpenRouter's compare page for openrouter/auto-beta reports a 2,000,000-token context window and a Free price label for the router itself, with the model marked as Provided by OpenRouter in the supplied excerpt. The page is set up to pit Auto Router (Beta) against flagship, coding, low-cost, and image generation categories including Claude Sonnet 5.5, GPT-6 Astra, and Nano Banana 2. Access is positioned as a single API key into hundreds of models routed through auto-beta, per the page summary line about OpenRouter API access in the supplied excerpt. The comparison harness exposes knobs for context length and price alongside the Free flag and 2M context, giving developers an at-a-glance view of how Auto Router (Beta) lines up against per-category leaders. No specific routing-behavior change distinct from stable Auto Router is surfaced in the excerpt.

OpenRouter documents openrouter/auto-beta as the experimental Auto Router variant where new routing improvements are tested before graduation to the main auto router, explicitly labeled beta quality in the supplied excerpt. The page directs developers to use the model via the OpenAI-compatible API at https://openrouter.ai/api/v1/chat/completions and shows drop-in TypeScript and Python SDK code for chat completions, image generation, and streaming with the slug openrouter/auto-beta. Billing follows the routed model rather than the router itself, so costs track whichever underlying model the request lands on according to the page description. Developers can inspect Activity logs or the response model attribute to see which underlying model was selected, and the docs link covers customization of the routing candidate set. The page also lists a Benchmarks tab and Compare tab next to a Try this model button for evaluation and side-by-side comparison.
