ChatGPT-4 was launched by OpenAI in March 2023 and represents a significant evolution in GPT (Generative Pre-trained Transformer) technology. In May 2024, Open AI released a faster ChatGPT-4o, which is better for complex tasks and available on the free tier for all users.
GPT-4, the LLM behind ChatGPT-4o, is larger and more complex than its predecessor, GPT-3.5. Its increased size allows for a more nuanced understanding of language and more sophisticated responses. It's better at tasks that require understanding subtleties and complexities in language, including humor, sarcasm, and cultural nuances.
