OpenAI drops the price of GPT-4 and adds features

OpenAI has revealed significant updates to its large language models, GPT-4 and GPT-3.5, at its inaugural developer conference. These enhancements include updated knowledge bases and a substantially expanded context window. The company also announced a customer protection program against copyright lawsuits, following in the footsteps of Google and Microsoft.

OpenAI introduced GPT-4 Turbo through an API preview, representing a considerable leap in capabilities. While the previous version of GPT-4, launched in March, was trained on data up to September 2021, GPT-4 Turbo is informed by information up to April 2023. OpenAI intends to release a production-ready Turbo model in the coming weeks.

One of the most notable improvements is the expanded context window in GPT-4 Turbo, now at 128K. This significantly enhances the model’s ability to understand queries and generate well-thought-out responses. In comparison, earlier versions of GPT-4 had context windows of only 8K and 32K. OpenAI’s larger context windows allow the model to work with more extensive inputs, equivalent to more than 300 pages of text in a single prompt.

GPT-4 Turbo is also cost-effective for developers. Input is priced at only $0.01 per 1,000 tokens, a basic unit of text or code. Output costs $0.03 per 1,000 tokens. OpenAI claims that GPT-4 Turbo is three times more cost-effective than its predecessors, which charged $0.03 for input.

This latest iteration can accept image prompts, process text-to-speech requests, and integrate with DALL-E 3, a feature introduced in October. The improvements in GPT-4 Turbo allow users to issue more complex instructions within a single prompt. For instance, users can specify their preferred coding language, such as XML or JSON, for generating code.

GPT-3.5 Turbo, released by OpenAI in March, is also receiving enhancements. It will have a default context window of 16K, the same functional updates as GPT-4 Turbo, and will be more affordable, with input priced at $0.01 and output at $0.002.

OpenAI also announced Copyright Shield, a program offering copyright indemnity to enterprise users. OpenAI will defend its customers and cover the associated legal costs in cases of copyright infringement claims. This initiative covers generally available features of ChatGPT Enterprise and OpenAI’s developer platform, ensuring legal protection for businesses utilizing these resources. Similar customer protection programs have been implemented by Google and Microsoft for their AI products.
