    “Stealth” model: Quasar Alpha

    4/3/2025

    It’s a prerelease of an upcoming long-context foundation model (1M tokens) from one of the model labs. It’s specifically optimized for coding, and available for free: https://openrouter.ai/openrouter/quasar-alpha

    This is the first time we’re enabling all OpenRouter users to try out a foundation model before it’s released publicly.

    Please provide feedback in the Quasar Alpha thread in Discord ( https://openrouter.ai/discord ) to help our partner improve the model and shape what comes next.

    ⚠️ Important Note: All prompts and completions will be logged so we and the lab can better understand how it’s being used and where it can improve.

    Try it. Build cool stuff. And let us know what you think! 💬
