A comparison chart from Google shows how Gemini Ultra and Pro compare to OpenAI's GPT-4 and Whisper, respectively.
Compared to GPT-4, a primarily text-based model, Gemini easily performs multimodal tasks natively. While GPT-4 excels in language-related tasks like content creation and complex text analysis natively, it resorts to OpenAI's plugins to perform image analysis and access the web, and it relies on DALL-E 3 and Whisper to generate images and process audio.

Google's Gemini also appears to be more product-focused than other models available now. It's either integrated into the company's ecosystem or with plans to be, as it's powering both Bard and Pixel 8 devices. Other models, like GPT-4 and Meta's Llama, are more service-oriented, and available for various third-party developers for applications, tools, and services.
