The rapid evolution of artificial intelligence (AI) has brought forth advanced language models that are transforming various industries. OpenAI‘s GPT-4 and its successor, GPT-4o, represent significant milestones in this progression. This article provides an in-depth comparison of these two models, examining their features, performance, and suitability for different applications.
What is GPT-4?
GPT-4, introduced on March 14, 2023, is a multimodal large language model capable of processing both text and image inputs to generate human-like text outputs. It marked a substantial advancement over its predecessors by enhancing creativity and collaboration in tasks such as composing songs, writing screenplays, and adapting to a user’s writing style. GPT-4 was made accessible through OpenAI’s ChatGPT Plus subscription and API, as well as integrated into Microsoft’s Copilot.
What is GPT-4o?
GPT-4o (“o” for “omni”), released in May 2024, expanded upon GPT-4’s capabilities by introducing multilingual and multimodal functionalities. This model can process and generate text, images, and audio, offering real-time reasoning across these formats. GPT-4o is designed to be faster and more cost-effective than its predecessors, providing GPT-4-level intelligence with improved performance across text, voice, and vision. Notably, GPT-4o’s image generation excels at accurately rendering text and precisely following prompts, leveraging its inherent knowledge base and chat context.
