If they use OpenRouter pricing then the Qwen3.5 models are going to be poor value.
The Qwen3.5 27B model on OR is $1.56/million tokens out (it used to be $2.4/mil).
Meanwhile Minimax M2.7 (a much larger model) is $1.2/mil out.
The smaller and medium tier Qwen3.5 models are only really cost effective if you run them yourself.
