To help more developers build with Muse Spark 1.3 at our contributor tier pricing, we're rolling out optimizations. In our testing, it has a 1-2% variance on our aggregate benchmarks compared to the standard tier. We've been using it for a while and noticed no differences in capability in our own usage.
The reception for Muse Spark 1.3 has been great - keep building and share feedback! We're eager to keep improving performance and capability.
