OpenAI Releases GPT 3.5 Turbo Command

OpenAI quietly released a new language model called "gpt-3.5-turbo-instruct" that aims to efficiently provide specific instructions, similar to the chat-focused GPT-3.5 Turbo. This new model replaces the existing Instruct model and certain text-based models. It maintains the same cost and performance as other GPT-3.5 models within a 4K context window and utilizes training data up until September 2021. Compared to GPT-3.5, gpt-3.5-turbo-instruct is not a chat model. Instead, it excels at directly answering questions and swiftly completing text-based tasks, aligning with its objective of effectively following instructions. OpenAI emphasizes that GPT-4 surpasses GPT-3.5 in understanding complex instructions, generating higher-quality outputs, and accomplishing these tasks at a faster speed and lower cost. The Instruct models, including this new version, serve as the foundation for significant improvements in ChatGPT, continuously enhanced through ongoing human feedback. These models demonstrate better performance in understanding and responding to human queries, with fewer errors and harmful content, despite having significantly fewer parameters than conventional GPT models, making them more favored. In January of this year, OpenAI introduced the instruct GPT model, aiming to reduce hallucinations and prompt the model to produce more "realistic" responses. Previous versions of GPT-3 achieved this because, as they explained, "it was trained on a large-scale internet text dataset with the goal of predicting the next word, rather than safely executing the desired language tasks." This model was inconsistent with users and often fabricated facts, whereas InstructGPT addresses this issue. The main difference between the new update and the old version is that GPT 3.5 Turbo is no longer conversational but rather instruction-oriented. This model avoids being "chatty" and is capable of following instructions without the need for additional prompting techniques.
