OpenAI has released a document explaining when to use each of its ChatGPT models, making it easier for users to understand the different options available. The document, titled “ChatGPT Enterprise – Models & Limits,” was posted on May 3 and provides an overview of the available models and their applications.
Currently, ChatGPT offers five models: GPT-4o, o3, o4-mini, o4-mini-high, and GPT-4.5. According to OpenAI, GPT-4o is the “omni model” with real-time information, suitable for tasks such as summarizing content, brainstorming ideas, and generating emails. As a multimodal model, it supports features like custom GPTs, image generation, canvas, advanced audio, and data analysis.
In contrast, GPT-4.5 is described as a “creative” powerhouse, offering better emotional intelligence, communication, and a creative approach to brainstorming. While similar to GPT-4o, GPT-4.5 is recommended for tasks that require more creativity.
For technical tasks, ChatGPT offers three reasoning models: o4-mini, o4-mini-high, and o3. The o4-mini model is suitable for quick technical tasks, such as STEM-related queries and programming. The o4-mini-high model is better suited for detailed technical tasks, including advanced coding, math, and scientific explanations. The o3 model excels in complex or multi-step tasks, such as strategic planning, detailed analyses, and extensive coding.
Users can choose between these models when they upgrade to ChatGPT Plus for $20. The document’s guidance is applicable to both enterprise and regular users, helping them select the most appropriate model for their needs.
