Llama 4 Scout or Morph V3 Fast: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick Llama 4 Scout for output tokens 2.4x cheaper ($0.50 vs $1.20 per million) and a larger context window (1.31M against 262K tokens).
No benchmark has tested both yet. Llama 4 Scout has results on SWE-bench Verified, AA Coding Index and LiveCodeBench (Vals AI); Morph V3 Fast has none yet. Compare them on price and context instead.
