GPT-4 is built to solve complex problems more accurately by using its extensive general knowledge and advanced problem-solving abilities.
GPT-4 is more reliable, and creative, and can handle nuanced instructions better than GPT-3.5.
OpenAI claims that GPT-4 is safer and more aligned than previous versions. According to their internal evaluations, GPT-4 is 82% less likely to generate disallowed content and 40% more likely to produce factual responses.
While GPT-4 represents a significant advance in language modeling, it still has some limitations that OpenAI is working to address. These include social biases, hallucinations, and adversarial prompts that can affect its responses' accuracy and reliability.
GPT-4 can accept both text and image prompts, allowing users to specify any vision or language task.
GPT-4 is available on ChatGPT Plus and as an API for developers to integrate into their applications and services. Several companies, including Duolingo, Khan Academy, Stripe, Be My Eyes, and Mem, are already using GPT-4 to enhance their services and applications, from language learning to customer support.
The cost of using GPT-4's API depends on the context window size and the number of prompt and completion tokens. GPT-4 with an 8K context window will cost $0.03 per 1K prompt tokens and $0.06 per 1K completion tokens, while GPT-4 with a 32K context window will cost $0.06 per 1K prompt tokens and $0.12 per 1K completion tokens.
