CPUs Aren't Dead. Gemma2B Out Scored GPT-3.5 Turbo on Test That Made It Famous
Gemma 2B scored ~8.0 on MT-Bench. GPT-3.5 Turbo scored 7.94. An 87-times-smaller model on a laptop CPU, no GPU anywhere in the stack. We published the full tape — every question, every turn, every score — so anyone can verify it. We found seven failure classes. Not hallucinations. Specific patterns: arithmetic where…
