Agent + model results
systems, not bare-model scores
| agent + model Claude Code + Claude Fable 5 | Terminal-Bench 2.1 | 83.2 % | community | Terminal-Bench Leaderboard |
| agent + model terminus-2 + Claude Fable 5 | Terminal-Bench 2.1 | 80.5 % | community | Terminal-Bench Leaderboard |
These scores measure the whole agent system (scaffold, tools, budgets) — they are never merged into the bare model’s numbers.
