AgentPTB sweep checkpoint. Cell sol-high — Codex / gpt-5.6-sol @ effort high.

Reading the eos field

248046 is <|im_end|>, the token the Qwen3.5 chat template ends every assistant turn with. Checkpoints missing it do not stop at end-of-turn and overrun the context window, so their eval numbers are a floor, not a measurement — compare them only against other checkpoints with the same eos status, or re-package before evaluating.

Cell note: best cell in the sweep

Mapping back to the figures

The repo id is {cell}.h{HHH}.{family}.{step}, where hHHH is the hour of the 100-hour run at which this checkpoint was written — the same x-axis the sweep figures use for eval panels (t_h). So a checkpoint drops onto the performance-over-time curve directly, and sorting repo ids within a cell sorts them chronologically.

hHHH is rounded down to whole hours for sortability; the exact value is the hours into run row above, and in agentic-ptb/INDEX.
