How QbitDojo labs work

  1. Step 1

    A live AI target

    Each lab is a real language model with its own instructions, guardrails and a secret flag it must protect.

  2. Step 2

    You attack it

    Talk to it like a red teamer would. Craft prompts, chain techniques and use hints if you get stuck.

  3. Step 3

    Capture the flag

    Get the model to reveal the flag to solve the lab, earn XP and climb the leaderboard.

  4. Step 4

    Then defend it

    In labs with Defense Mode, write the hardened system prompt that blocks the attack you just used.
