In terms of performance, Gemini has demonstrated strong results, especially in the Massive Multitask Language Understanding (MMLU) benchmark, slightly outperforming GPT-4. For instance, on text-only questions, Gemini scores 90% while GPT-4 scores 86%. On multimodal questions, Gemini scores 59% against GPT-4's 57%. However, experts suggest that while Gemini's benchmark scores are impressive, it's challenging to interpret these numbers fully without transparency about the training data and methodologies.
