Performance Comparison: Which AI is Better?
1. Accuracy and up-to-dateness
ChatGPT: GPT-4o excels at logical reasoning (MMLU benchmark 88.7%) and creative responses. Relies on web search (based on Bing) for up-to-date information, and data freshness is somewhat limited.
Grok: Grok 3 is strong in scientific questions and truth-based answers (accuracy around 85%, based on benchmarks). It is reliable in providing up-to-date information via X platform and web search, especially in science and technology.
2. Creativity
ChatGPT: Human and emotional output in creative writing such as stories, poems, and lyrics. For example, creating a warm and vivid story when writing a fairy tale.
Grok: Creative writing is possible, but more concise and logical than ChatGPT. Humor and external perspectives ('alien perspectives') provide a unique style.
3. Multimodal performance
ChatGPT: Image creation is fully supported only in paid plans (DALL-E 3). Image analysis is precise but limited in the free version.
Grok: Supports multimodal functions such as image analysis, PDF processing, etc. Image upload and basic analysis are possible even in the free version. Example: Useful for summarizing research paper PDFs.
4. Speed
