GPT-6.1 Sol or Weaver (alpha): which to pick
Only GPT-6.1 Sol has a coding score, 82.4 on the Vibe Coding Index; Weaver (alpha) has none, so the two cannot be ranked on coding.
Pick Weaver (alpha) for output tokens 13.3x cheaper ($0.75 vs $10.00 per million).
No benchmark has tested both yet. GPT-6.1 Sol has results on LiveBench coding, LMArena WebDev and Terminal-Bench 4 (Vals AI); Weaver (alpha) has none yet. Compare them on price and context instead.
