Zed benchmark

The fastest median in the index, and the reason is architectural rather than clever prompting: the editor is fast, the diff review is instant and almost no time is lost to interface latency. Correctness sits in the middle of the agent group, so the right read is that it costs the least time per attempt rather than that it is the best at any single attempt.

What agent performance looked like in practice

Across 45 recorded executions this product met the published pass criterion cleanly 32 times, partially 5 times and failed 8 times. The rows above carry the reviewer note for every non clean outcome, which is the only way to tell a product that fails loudly from one that fails quietly.
