OpenAI model names have been confusing, but the company is finally taking steps to make it easier for users to understand the different ChatGPT models.
OpenAI quietly posted an article titled “ChatGPT Enterprise – Models & Limits” on May 3.
While it provides an overview of all the available models and when to use one over another for enterprises, these advices are also applicable to regular users.
Right now, ChatGPT offers five models – GPT-4o, o3, o4-mini, o4-mini-high, and GPT-4.5.
What to choose between GPT 4o and 4.5?
According to the document, GPT 4o is the “omni model” with real-time information, and it should be used for summarizing content, brainstorming ideas or emails.
Since it’s a full-fledged multimodal, you can use nearly all the features, ranging from custom GPTs to image generation, canvas, advanced audio, and data analysis.
On the other hand, GPT-4.5 is your “creative” powerhouse, and it offers better emotional intelligence, communication and a creative approach to brainstorming.
It’s a lot like the GPT-4o, but if you prefer more creativity, GPT-4.5 should be your first choice.
What to choose between o4-mini, o4-mini-high and o3?
ChatGPT offers three reasoning models to regular users, but which one should you be using?
As per the document, o4-mini is fast for technical tasks, such as quick STEM-related queries, programming, visual reasoning.
On the other hand, o4-mini-high is best at detailed technical tasks, such as advanced coding, math, scientific explanations and higher accuracy.
Unlike these two models, o3 stands out in complex or multi step tasks, such as strategic planning, detailed analyses, extensive coding, advanced math, science, coding, and visual reasoning.
You’ll be able to choose between these models only when you pay $20 for ChatGPT Plus.
