While I agree directionally, I'll caveat that "cost per token" != "cost per task". In the case of Qwen3.6 it tends to think 1.6x more than Haiku, so the cost of Haiku on the same tasks tends to only be about double. More detail from comparing their Artificial Analysis metrics:

    COST PER TOKEN   ≠   COST PER TASK  
    output tokens per index run:
       Haiku 4.5    87.3M   (79.3M reasoning + 8.0M answer)
       Qwen3.6     143.2M   (131.7M reasoning + 11.5M answer)
       → Qwen emits 1.64× more output
  
    ── output speed (tokens / sec) ──────────  raw rate · higher = faster
       Qwen3.6     100%   ~196 t/s
       Haiku 4.5   ~47%   ~93 t/s
                                                  → Qwen ~2.1× faster per token

                                                  → Qwen ~1.3× FASTER to a solution

     Claude Haiku 4.5       37.1            $620            (slower)
  
     → Qwen wins all three. The reasoning blow-up (1.64×) is smaller than
       the raw-speed edge (2.1×), so Qwen stays ahead per task.
