GPT-4 Turbo is the latest model from OpenAI (this article was updated at the end of April 2024), and was introduced in November 2023. Since then, the model has undergone several upgrades, with OpenAI launching a much more improved model version, gpt-4-turbo-2024-04-09, at the beginning of April.
GPT-4 Turbo has a 128,000-token context window, which is the equivalent of 300 pages of text in a single prompt, according to OpenAI. It also has training data knowledge up to December 2023.

Compared to the January 2024 version of GPT-4 Turbo, OpenAI says the updated version performs better on a series of benchmarks used to test the proficiency of AI models, including MMLU (Measuring Massive Multitask Language Understanding), MATH (Measuring Mathematical Problem Solving With the MATH Dataset), and GPQA (A Graduate-Level Google-Proof Q&A Benchmark).
When referring to the updated version of GPT-4 Turbo, OpenAI CEO Sam Altman said that GPT-4 is “now significantly smarter and more pleasant to use,” as seen below.
