The story goes that Goliath showed up in armor, backed by an army, and everyone assumed the fight was already decided. Then a shepherd with a sling walked out instead, and the size of the opponent stopped being the thing that mattered.
That's basically what happened on Terminal-Bench 2.1 this week.
The setup
Terminal-Bench 2.1 is where the frontier labs go to flex. It's 89 hard, realistic terminal tasks: compiling code, debugging broken builds, configuring servers, recovering corrupted data, training models. No multiple choice, no partial credit. An independent verifier checks the final state, and either it passes or it doesn't.
The names at the top of that leaderboard are the ones you'd expect: Codex CLI, Claude Code, backed by teams with nine figure compute budgets and the biggest models money can rent. This is Goliath's turf.
