Answer checks

16/16 tasks

Method

Sixteen exact-output tasks and repeated greedy controls per candidate; warm four-request code/chat throughput includes first-token time and final drain.

Limits

The selected candidate passed its bounded checks; rejected and unfinished candidates remain in the table. Configured context is not long-context quality proof.

What did not work

  • The selected candidate passed its bounded checks; rejected and unfinished candidates remain in the table.
