Agent + model results
systems, not bare-model scores
| agent + model Artificial Analysis harness + Magistral Small 2509 | Terminal-Bench Hard | 4.5 % | independent | Artificial Analysis |
| agent + model Artificial Analysis harness + Magistral Small 2509 | Terminal-Bench 2.1 | 4.5 % | independent | Artificial Analysis |
These scores measure the whole agent system (scaffold, tools, budgets) — they are never merged into the bare model’s numbers.
