Gemma 3 4B vs Sonar Pro
Updated October 21, 2026. 5 benchmarks have a result for both. Coding is ranked on the Vibe Coding Index; every other board is shown as published.
Decision reading
Neither model has a coding score yet, so the two cannot be ranked on coding.
Gemma 3 4B has the edge where output tokens cost 200.0x less, and where what matters is LiveCodeBench (Artificial Analysis run) or AA Intelligence Index, where it leads.
