GPT-4 is a strong general-purpose model, known for its accuracy, reasoning, and longer context window. However, for now, GPT-4 is rather seen as a legacy model, capabilities of which are more limited than those of newer ones.
This model still performs well in most tasks but may be slower compared to lighter models. It is suitable for:
- Writing essays, articles, or marketing texts
- Explaining complex topics
- Working with structured tasks like planning or decision trees
GPT-4o balances both speed and quality, being much faster than GPT-4 while matching or exceeding its performance on many tasks.
So, you can use GPT-4o when you need:
- Real-time or faster responses
- High-quality reasoning
- Multimodal support (e.g., working with images or files)
GPT-4.5
This model offers enhanced conversational abilities and a broader knowledge base, resulting in more natural interaction and higher answer accuracy.
So, GPT-4.5 performs following tasks even better than previous models:
- Programming Assistance: Developers can leverage GPT-4.5 for code generation, debugging, and offering solutions to complex programming challenges.
- Language Translation and Communication: With its multilingual support, GPT-4.5 serves as a valuable tool for accurate translations and cross-lingual communications.
- Educational Support: The model can aid in tutoring, providing explanations, and answering questions across a wide range of subjects.
o1
Unlike previously discussed models, o1 is a lightweight model optimized for speed. It handles basic tasks quickly but does not match GPT-4 in reasoning or complexity. It’s suitable for simple queries and casual conversations.
Thus, o1 is best for doing various tasks that do not require AI’s advanced capabilities. For example:
- Quick summaries
- Basic Q&A
- Simple explanations or translations
o3 models
There are two types of o3 models: o3-mini and o3-mini-high. The former is a compact model that is despite being fast, is still designed to excel in advanced reasoning tasks like content creation, writing and advanced research.
Hence, o3-mini offers a compelling combination of speed, efficiency, and flexibility for both production and development use cases.
In turn, o3-mini-high is a model with exceptional STEP capabilities. It offers particular strength in science, math, and coding tasks – all while maintaining the quality of answers with an increased speed compared to other models.
