Swipe the table sideways for more columns.

Ranks follow the score as shown, so equal numbers share a rank. Results as published by APEX-Agents; we do not re-run them.

Progress over time

Tasks passed, plotted at each model's release date, higher is better. Each model counts once, at its best setting. Scores are today's, not launch day's; 1 model without a known release date is left off. Hover or tap a mark for its model.

Best score so far

Every model at its release date. The line moves each time a new release beats every earlier one, and each new best is named where there is room.

Best score by lab

Each lab's best so far, stepping whenever one of its releases beats its own earlier models. The 6 labs with the best scores today; 5 others not drawn.
