# BenchCell

[common]\
data class [BenchCell](index.md)(val isl: [Long](https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-long/index.html), val osl: [Long](https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-long/index.html), val lateIsl: [Long](https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-long/index.html) = 0)

One cell of the sweep ([Modelverse.bench](../Modelverse/bench.md)): [isl](isl.md) prompt tokens in, [osl](osl.md) tokens decoded, both exact (the prompts are synthesized in the model's own vocabulary at that length and the decode is pinned to the count). A positive [lateIsl](lateIsl.md) adds one more session with a prompt of that many tokens that joins once every regular session has streamed its first token, the shape of a long prompt arriving while others decode; the row then reports what its prefill cost the running sessions (`itlMaxMs`, `itlP99Ms`) and what the prompt waited itself (`lateTtftMs`). The command line spells a cell `ISL:OSL` or `ISL:OSL+LATE`.
