Zhiqing Sun(@EdwardSun0909):Excited to share Muse Spark 1.1 with you! It’s our first model available in the API, built to excel in agentic and coding. I’m incredibly proud of what the team has achieved in such a short time, from 1.0 to 1.1. The momentum is high, and we’re still training larger models!
