    st.write(
        "Real-world robotics faces a fundamental challenge: environments are dynamic and change over time, "
        "making consistent evaluation of robot performance difficult. World models offer a solution by "
        "learning to simulate complex real-world interactions from raw sensor data. We believe these learned simulators will enable "
        "robust evaluation and iterative improvement of robot policies without the constraints of a physical testbed."

    st.markdown("#### Compression Challenge")
    st.write(
        "In the Compression Challenge, your task is to train a model to compress our robots logs effectively while preserving the critical details needed to understand and predict future interactions. Success in this challenge is measured by the loss of your model—the lower the loss, the better your model captures the complexities of real-world robot behavior."

    st.markdown("#### Sampling Challenge")
    st.write(
        "In the Sampling Challenge, your task is to predict a future video frame two seconds in the future given a short clip of robot interactions. The goal is to produce a coherent and plausible continuation of the video, which accurately reflects the dynamics of the scene. Your submission will be judged on how closely it matches the actual frame."

    st.markdown("#### Evaluation Challenge")
    st.write(
        "The Evaluation Challenge tackles the ultimate question: Can you predict a robot's performance in the real world without physically deploying it? In this challenge, you will be provided with many different policies for a specific task. Your task is to rank these policies according to their expected real-world performance. This ranking will be compared with the actual ranking of the policies."
