Our assessment in one line

Interesting, not yet dependable. Emergent has the most ambitious agent architecture in this index: give it a real brief and it produces a task decomposition that reads like something a competent tech lead would write, then works through it across many files without asking permission every thirty seconds. When it lands, it lands big. Our panel gave it 4.2 on agent performance, joint third highest alongside v0. The trouble is variance. The same brief run twice produced materially different quality, and the failure mode is quiet: plausible code that does not work, discovered later than you would like.
