OpenAI presents GPT-4 Turbo, a faster and more cost-effective version of its advanced language model, GPT-4. This new model, announced during OpenAI’s DevDay, is designed to be accessible to all users of ChatGPT Plus.

GPT-4 Turbo distinguishes itself by being up-to-date with global events up until April 2023, a notable advancement from its predecessor, which was trained on data only until September 2021. This enhancement allows GPT-4 Turbo to provide more accurate and contextually relevant responses. Additionally, it supports a context window of 128K, equivalent to 300 pages of text, allowing for more extensive and complex interactions in a single prompt.

GPT-4 Turbo also introduces improvements in function calls and excels in tasks that require meticulous following of instructions. Developers will benefit from the new JSON mode, which ensures the generation of syntactically correct JSON outputs. The introduction of the ‘seed’ parameter is another significant feature, providing more predictable and consistent outputs from the model.

The pricing model of GPT-4 Turbo is set to disrupt the market. At $0.01 per 1,000 tokens of input, which translates to roughly 750 words, it is three times more affordable than GPT-4 for input tokens and twice as cheap for output tokens.

OpenAI also announced updates for GPT-3.5 Turbo, which will feature a 16K context window, enhanced instruction tracking, JSON mode, and parallel function calls. The pricing for GPT-3.5 Turbo will be three times less than its predecessor.

Amidst these advancements, OpenAI has introduced Copyright Shield to protect its users from copyright infringement claims, following the lead of Microsoft, Google and Adobe. This protective measure will apply to the developer platform functions and ChatGPT Enterprise services.

This move comes as OpenAI faces a lawsuit from Sarah Silverman and two writers, who claim the company used their books without permission for training GPT-4. George R. R. Martin has also filed a lawsuit, accusing OpenAI of massive-scale theft after ChatGPT generated content resembling his ‘Game of Thrones’ series.
