CFE-Bench: New STEM reasoning benchmark reveals frontier models struggle with multi-step logic
Researchers introduced CFE-Bench (Classroom Final Exam), a multimodal benchmark using authentic university homework and exam problems across 20+ STEM domains to evaluate LLM reasoning capabilities. Gemini 3.1 Pro Preview achieved the highest score at 59.69% accuracy, while analysis revealed frontier models frequently fail to maintain correct intermediate states in multi-step solutions.
