Qwen3.6 at which model size and quantization? I already think Opus 4.6 is usable but still dumb as bricks. A 20% cut off that feels like it would still be unusable. And that's not even getting to the annoyance of setting everything up to run locally & getting HW that can run it locally which basically looks like a Macbook M4 these days as the x86 side is ridiculously pricey to get decent performance out of models.
At their highest model size and quant. We are discussing price and quality at the top, not what you can run on the lower end.
So the starting point is Opus 4.7 pricing and we're contrasting alternatives near the top end (offered across multiple providers).
Also I said 20% was hyperbole, meaning far too high.
