What is the significance of OpenAI making GPT-4 generally available?
OpenAI’s decision to make GPT-4 generally available through its API marks a significant advancement in the accessibility of advanced AI technology. This means that a wider range of developers who have a proven track record with OpenAI’s API can now integrate GPT-4, the latest text-generating model, into their applications and services. This widespread availability fosters innovation and allows more developers to leverage the enhanced capabilities of GPT-4, such as its ability to generate text (including code) and accept image and text inputs, leading to a broader range of AI-powered applications. The move also signals OpenAI’s confidence in the model’s stability and scalability, as well as their commitment to expanding the reach of powerful AI tools. OpenAI plans to extend access to new developers by the end of the month and subsequently increase availability limits based on compute resources.

What are the key capabilities and limitations of GPT-4?
GPT-4 represents a significant step forward in text generation and multimodal input processing. It can generate text, including code, and, unlike its predecessor GPT-3.5, it can accept both image and text inputs. GPT-4 demonstrates «human-level» performance on various professional and academic benchmarks, showcasing its advanced reasoning and problem-solving abilities. However, it’s important to acknowledge that GPT-4 is not without its limitations. Like other generative AI models, it can «hallucinate» facts and make reasoning errors, sometimes with high confidence. Furthermore, it doesn’t learn from its experience and can struggle with complex tasks, such as introducing security vulnerabilities into the code it generates. Despite these limitations, GPT-4’s capabilities make it a powerful tool for a wide range of applications, and OpenAI is continuously working to improve its performance and address its shortcomings.

What are OpenAI’s plans for fine-tuning GPT-4 and deprecating older models?
OpenAI plans to allow developers to fine-tune both GPT-4 and GPT-3.5 Turbo with their own data, a feature that has been available for some time with other OpenAI text-generating models. This capability is expected to be available later this year, enabling developers to customize the models for specific use cases and improve their performance on specialized tasks. Additionally, OpenAI announced that it will deprecate older models available through its API, starting January 4, 2024, to optimize its compute capacity. Specifically, GPT-3 and its derivatives will be replaced with new «base GPT-3» models that are presumed to be more compute-efficient. Developers using the older models will need to upgrade their integrations manually by the specified date, and those wishing to continue using fine-tuned older models beyond January 4 will need to fine-tune replacements atop the new base GPT-3 models. OpenAI has stated they will provide support to users previously fine-tuning models to make the transition smoother.
