GPT-5.4 or Hy-MT2-30B-A3B: which to pick
Only GPT-5.4 has a coding score, 64.4 on the Vibe Coding Index; Hy-MT2-30B-A3B has none, so the two cannot be ranked on coding.
Pick Hy-MT2-30B-A3B for output tokens 50.8x cheaper ($0.295 vs $15.00 per million).
No benchmark has tested both yet. GPT-5.4 has results on LMArena WebDev, AA Coding Index and LiveCodeBench (Vals AI); Hy-MT2-30B-A3B has none yet. Compare them on price and context instead.
