Card stats

  • Intelligence ▲ higher wins

    Intelligence Index: a composite score from 10 hard evaluations covering reasoning, knowledge, coding, agents and science.

    48.1

    beats 84% of deck

  • Hallucination ▼ lower wins

    Hallucination rate: of the questions a model gets wrong, how often it confidently makes up an answer instead of saying it doesn't know. Lower wins.

    33 %

    beats 81% of deck

  • Context ▲ higher wins

    Context window: how many tokens of input the model can consider at once.

    1M

    beats 65% of deck

  • Knowledge ▲ higher wins

    Training-data cutoff: the most recent month the model learned about. Later wins. N/D means the lab hasn't disclosed it, and an N/D card loses this stat.

    N/D

    beats 16% of deck

  • Speed ▲ higher wins

    Median output speed in tokens per second, measured on the labs' own APIs.

    175 tok/s

    beats 76% of deck

  • Response ▼ lower wins

    End-to-end response time: seconds to receive a 500-token answer, thinking time included. Lower wins.

    73.4 s

    beats 29% of deck

  • Price ▼ lower wins

    Blended price per million tokens (3:1 input to output). Lower wins.

    $2.00

    beats 39% of deck

  • Modalities ▲ higher wins

    Number of supported input and output modalities: text, image, audio and video.

    4

    beats 81% of deck

Knowledge: The lab hasn’t published a training-data cutoff, so this card shows N/D and loses the Knowledge stat.
