Gemma 3 27B or Weaver (alpha): which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick Gemma 3 27B for output tokens 2.5x cheaper ($0.30 vs $0.75 per million) and a larger context window (131K against 8K tokens).
No benchmark has tested both yet. Gemma 3 27B has results on Aider polyglot, AA Coding Index and LiveCodeBench (Artificial Analysis run); Weaver (alpha) has none yet. Compare them on price and context instead.

Benchmark by benchmark
Every board either model has a result on, a category to a fold; bars are each result on a 0 to 100 scale. Only one model is measured on each, so no row names a leader.
