New models
GPT-4
gpt-4-0613 includes an updated and improved model with function calling.
gpt-4-32k-0613 includes the same improvements as gpt-4-0613, along with an extended context length for better comprehension of larger texts.
With these updates, we’ll be inviting many more people from the waitlist to try GPT-4 over the coming weeks, with the intent to remove the waitlist entirely with this model. Thank you to everyone who has been patiently waiting, we are excited to see what you build with GPT-4!
GPT-3.5 Turbo
gpt-3.5-turbo-0613 includes the same function calling as GPT-4 as well as more reliable steerability via the system message, two features that allow developers to guide the model’s responses more effectively.
gpt-3.5-turbo-16k offers 4 times the context length of gpt-3.5-turbo at twice the price: $0.003 per 1K input tokens and $0.004 per 1K output tokens. 16k context means the model can now support ~20 pages of text in a single request.
