System One Bench

Reports, examples
and firsthand accounts.

Read what people tried with Jev, what they measured and what they still do not know. Each record connects the original report to a specific experiment you could run in System One.

19 reviewed records. External results are author-reported. We have not independently rerun them. Anecdotes, our own experiments and vendor guidance carry separate labels.

How to read a result

Use a result to choose the next test

A passage-ranking result can justify testing a context selector. It cannot establish that a coding agent finishes faster. The guides explain that next step, including what the Engine accepts today.

Bench retains negative results. The routing ablation found no added benefit from its Jev signal. Our conservative log policy increased the modeled bill. Those findings help decide where a model call is worth testing.
