The scores are in blog post's bar chart. For Terminal Bench 2.1, Strands harness (Fable 5) scored 69.7 while Claude Code (Fable 5) scored 61.8. This is on high effort.
I hear you tho about saturation. We're working on a follow-up deep dive post with more harnesses, so could look into Terminal Bench 4.0?
Then I'm really confused. Terminal Bench 2.1 scores on Artificial Analysis are like 80-90%. https://artificialanalysis.ai/evaluations/terminalbench-2-1
AA isn’t testing different harnesses there, they’re testing different models on the same common harness:
“We run Terminal-Bench 2.1 with the Terminus 2 agent harness in an e2b sandbox and report pass@1 averaged over 3 repeats per task.”
This is a different agent harness than those Strands was testing with, and there’s no guarantee the pass criteria matches up the same either.
