|
|
| ## 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`. |
