GPT-3 is a language model developed by OpenAI in 2020. As the third generation in the GPT series, it builds on the capabilities of the previous GPT-2 model. GPT-3 is trained on massive text datasets and uses a transformer neural network architecture. It achieves strong performance on natural language processing tasks like text generation and classification.
A key strength of GPT-3 is few-shot learning, allowing it to perform new tasks after seeing just a few examples without extensive retraining. This makes GPT-3 highly flexible and adaptable. It represents a major advance in large language models, though it is limited to only text inputs and outputs.
GPT-3 was a breakthrough in natural language AI when released. Its 175 billion parameters allowed remarkably human-like text generation based on short prompts. The scale of data and compute used to train GPT-3 enabled more robust text comprehension and synthesis abilities compared to prior models. Developers could tap into GPT-3's capabilities through API access, powering new applications. Overall, GPT-3 showcased the potential of large language models to perform complex linguistic tasks. It set the stage for even more advanced successors.
GPT-4 builds significantly on GPT-3, taking language AI to new levels. GPT-4 is multimodal, accepting both text and image inputs. This allows it to excel at combined language-vision tasks like caption generation.
GPT-4 is also massively larger than GPT-3, as it is trained on far more data across modalities. Enhanced steerability gives GPT-4 more precision when guided. GPT-4 achieves higher accuracy, more nuanced writing, and broader capabilities than GPT-3, representing the next evolution in advanced language models. GPT-4 surpasses GPT-3, its predecessor, across key benchmarks.
