there is no difference... each case may be different, I have a local qwen gpu setup... and is fast... but not as fast as claude. Fable is amazing and if it cost the same as my qwen setup I'll be running fable and never had qwen in first place. But Fable is crazy expensive, Qwen is not as fast but cheaper... Haiku is fucking dumb IN MY HANDS... BUT my local qwen is quick enough to be briefed, get the idea and delegate. I work with Fable mostly delegating to opus/sonnet and it's cheaper than just fable, I can't stand working with opus or the other models.
Why Qwen directing the others? For the things claude refuse, Qwen can make very specific questions and still get an answer without triggering the thing.
I am using Haiku 5 and it’s amazing for the cost. I almost always use it instead of Opus5.5 for simpler tasks. In my experience it’s much better than the Qwen models!
