Performance–cost parity of task decomposition versus frontier reasoning models

Determine whether multi‑agent task decomposition can systematically match frontier reasoning model performance while achieving substantially reduced computational and environmental costs.

Background

Mimosa attains ScienceAgentBench success rates comparable to those reported with very costly frontier reasoning models, suggesting a pathway to frugal scientific AI. However, the generality of this observation is not established. Establishing whether decomposition can consistently reach similar performance at lower cost would guide practical deployment and model–architecture choices.

References

Whether such decomposition can systematically match frontier reasoning model performance at substantially reduced computational and environmental cost remains an important open question.

Whether a set of small, job-specialised agents can match a large general model on this task is the natural next experiment; the per-stage model overrides in the released runner are there to make it easy to run.
