- Efficient in handling short to medium-length conversations.
Use Cases:
- Chatbots for customer service.
- Writing assistance for blogs, essays, and articles.
- Moderate-level coding support.
Limitations:
- Struggles with highly complex reasoning tasks.
- Shorter context window for handling long documents.
GPT-4
Launched in 2023, GPT-4 improved significantly on the strengths of GPT-3.5. It was designed to handle more sophisticated tasks with improved reasoning, problem-solving, and the ability to better understand nuanced prompts.
Key Features:
- Longer context window (up to 32k tokens).
- More advanced reasoning capabilities compared to GPT-3.5.
- Enhanced natural language processing, making it suitable for detailed reports and technical writing.
Use Cases:
- Analyzing large datasets for business insights.
- Creative content generation with better accuracy and style matching.
- Complex coding tasks and debugging.
Limitations:
- More resource-intensive, which may impact processing time for large-scale projects.
The New O1 Preview Series: O1-Preview and O1-Mini
OpenAI's recent addition, the O1 preview series, promises advanced capabilities, primarily focusing on solving complex reasoning tasks. However, it also brings a smaller, faster variant in the form of O1-mini, making it ideal for coding tasks and other quick operations.
O1-Preview:
- Context window: 128k tokens, significantly larger than GPT-4.
- Advanced reasoning: Tailored for solving intricate problems that require complex decision-making and processing.
- Output size: Supports up to 32k tokens per output.
O1-Mini:
- Faster and cheaper: O1-mini is a cost-efficient alternative that prioritizes speed.
- Optimized for coding: Although it’s smaller in size, it performs well on tasks like coding where quick responses are required.
- Limitations: Fewer features than the O1-preview, including a smaller output limit of 64k tokens【31†source】.
