Multi-agent workflows beat solo runs on quality, but solo is ~3x faster
kevinkern · x · 2026-09-27
The author ran a small experiment comparing how to combine Opus 5.5 and Astra on a real task:
- Astra orchestrating Opus 5.5 delivered the best overall result
- Opus 5.5 with Astra as reviewer offered the best quality/cost balance
- Solo runs weren't far behind in quality and were 3x faster, at much lower cost
Takeaway: multi-agent workflows improve results, but often not enough to justify the added runtime. The author notes this was a small experiment and results may differ with many parallel threads.
