How to Use Different ChatGPT Models For Beginners (2025)

The video explains the features, best use cases, and differences of various OpenAI models, from the quick and affordable GPT40 Mini to the powerful GPT03 capable of complex reasoning and research. It guides beginners in selecting the appropriate model based on their needs, whether for simple tasks, creative writing, detailed analysis, or mathematical problem-solving.

The video provides an overview of various OpenAI models, explaining their features, best use cases, and differences to help beginners choose the right one for their needs. It starts with the smallest model, GPT40 Mini, which is designed for quick, everyday tasks that require minimal reasoning. This model is fast, cost-efficient, and unlikely to be rate-limited, making it ideal for simple questions, quick fact-checking, and basic image analysis. Its primary advantage is speed and affordability for routine tasks without deep complexity.

Next, the video discusses GPT40, a versatile all-rounder model suitable for a wide range of tasks such as writing essays, creating video scripts, translating languages, and analyzing images. It excels at formatting information in an easy-to-understand way and can handle multimodal inputs like images. GPT40 also supports voice mode, enabling users to have spoken conversations, search the internet, and multitask hands-free, which enhances its utility for everyday interactions and quick information retrieval.

The third model covered is GPT4.5, which is tailored for creative writing, emotional intelligence, and human-like interactions. It produces more natural, empathetic responses and is particularly useful for drafting social media content, persuasive texts, or professional communication. However, GPT4.5 has a limited usage quota of around 50 messages per week due to its high cost. It is slower than other models but offers a nuanced understanding of human emotions, making it suitable for tasks requiring a human touch.

The most powerful model discussed is GPT03, an AI agent capable of performing complex, multi-step tasks. It can analyze images in great detail, crop and reason about visual data, and cross-reference information from the web. GPT03 can generate detailed research reports, perform advanced business analysis, and use various tools to accomplish intricate tasks. Its ability to reason, browse the internet, and utilize tools makes it the top choice for STEM, research, and detailed problem-solving, though it is more resource-intensive and has usage limits.

Finally, the video explains the capabilities of GPT04 and GPT04 Mini High, which are specialized for mathematical problems and data analysis. These models excel at solving complex calculations, generating synthetic data, and working with structured information like spreadsheets. They are ideal for business calculations, profit analysis, and mathematical modeling. The presenter also clarifies the differences between models like deep research and GPT03, emphasizing that GPT03 can perform research and data analysis more efficiently, making it the most suitable for in-depth, complex tasks that require reasoning, tool use, and internet browsing.
