Hands-on: Astra coordinating Opus 5.5 wins on quality, but at higher cost
kevinkern · x · 2026-09-27
The author ran a small experiment on a real task comparing several ways to combine Opus 5.5 and Astra:
- Astra coordinating Opus 5.5: best overall result
- Solo Opus 5.5 with Astra reviewing: better quality-cost balance
- Solo runs: slightly behind, but much cheaper
The author notes this is a personal, small-scale test — whether the findings hold with many parallel threads remains an open question.
