It's worth looking into for the decreased cost if nothing else

I noticed Sol seems to get rate limited enough to get pretty annoying now. Same for me with every model release that isn't really better than the last, leaving the old model doesn't mean much when they start shifting over capacity.

You’re not missing out. Astra was good for a couple of days and is now so quantized it’s often worse than 5.6. And 6 sol is a nothing burger to keep a wedge in the media when Opus 5.5 came out.
