Gemini models have been evaluated for their vision capabilities, including document extraction. The results show that Gemini models use significantly fewer tokens per image compared to GPT-4o models, are faster at processing inputs, and slightly more accurate in factuality. However, they generate more completion tokens than GPT-4o models. These findings suggest that Gemini models have potential advantages over GPT-4o models for certain vision tasks. The AI proxy allows users to easily integrate Gemini into their applications with a single-line code change, making it easy to experiment with the model's multimodal capabilities and fine-tune prompts to meet specific needs.
