What is a Base Model?
A base model is a pre-trained language model that serves as the foundation model for fine-tuning tasks using a vast dataset.
Prominent base models from OpenAI include GPT-3.5, GPT-4, GPT-4o, among others.
Main Base Models from OpenAI
OpenAI mainly releases various base models through its GPT (Generative Pre-trained Transformer) series.
1. GPT-3
- Release Year: June 2020
- Description: With 175 billion parameters (which refer to weights and biases), GPT-3 was one of the largest language models at its release. It was trained on an extensive array of text data collected from various internet sources, including Wikipedia.
2. GPT-3.5
- Release Year: March 2022
- Description: An upgraded version of GPT-3, GPT-3.5 introduces more refined algorithms and optimized learning methods. It provides superior prompt comprehension skills and response generation abilities. The naturalness and accuracy in conversational interactions have notably improved.
3. GPT-4
- Release Year: March 2023
- Description: This multimodal model can process not just text but also image inputs. It boasts more parameters and enhanced performance, specifically designed to provide safer and more ethical responses in user interactions.
4. GPT-4o
- Release Year: May 2024
- Twice as fast as GPT-4 while cutting costs by half. It can process text and images simultaneously and supports both voice and video inputs.
Other popular base models include the Claude series by Anthropic and the Gemini series by Google.
