what is the ammount od system RAM you have? If you've got enough Strata with Qwen3.8 Flash Next could be a great option. For me it works great on Pi. I've developed an extension, that made it useable for very long chats and it now helps developing on huge Repos like GrandOrgue. Sometimes it beat Sonnet 5.5 in this configuration, but the most efficient way is to combine it with Opus 5.5, when it gets stuck, or its plans are not optimal. After having the Max Subscription for 2 month I'm now able to keep the Pro subscription and still get good results.
