shuchaobi · x · 2026-07-11
A repost shared the coding agent results for Muse Spark 1.1:
- Scored 69 on the Opencode harness in the Artificial Analysis Coding Agent Index
- Slightly lower than GPT-5.5 (medium) which scored 71 in Codex
- But higher than Claude Opus 4.8 (medium) which scored 67 in Claude Code
- Its main advantage is high cost-efficiency, costing about $1.4 per task
- The tradeoff is that it takes longer per task
The original post also mentioned that this coding agent is now available for trial and welcomed feedback.
