GPT-3.5 Turbo Instruct
OpenAI has unveiled its latest AI language model, “gpt-3.5-turbo-instruct,” designed to efficiently follow specific instructions, akin to the chat-oriented GPT-3.5 Turbo. This new model replaces existing Instruct models and certain text-based models while maintaining the same cost and performance parameters as other GPT-3.5 models.
GPT-3.5 Turbo Instruct vs. GPT-3.5
Unlike GPT-3.5 Turbo, which is primarily designed for conversation and mimicking human-like responses, gpt-3.5-turbo-instruct focuses on directly answering questions and swiftly completing text tasks following instructions effectively. OpenAI highlights its superiority in comprehending complex instructions, generating high-quality output, and doing so at a faster pace and lower cost compared to GPT-3.5.
Instruct Models and Their Significance
Instruct models, including this new release, serve as a crucial foundation for advancements seen in AI models like ChatGPT. They have been refined continuously through human feedback during and after pre-training. These models excel in understanding and responding to human queries with fewer errors and less harmful content, even when they have significantly fewer parameters than regular GPT models.
We've just launched fine-tuning for GPT-3.5 Turbo! Fine-tuning lets you train the model on your company's data and run it at scale. Early tests have shown that fine-tuned GPT-3.5 Turbo can match or exceed GPT-4 on narrow tasks: https://t.co/VaageW9Kaw pic.twitter.com/nndOyxS2xs

OpenAI introduced the instruct GPT models in January with the aim of reducing hallucinations and encouraging the generation of more truthful and less toxic responses. GPT-3 had a tendency to produce inaccurate information, as it was trained to predict the next word based on a vast dataset of internet text, rather than to provide safe and accurate responses to user queries. Instruct models addressed this limitation.
Key Highlights in the Update
The primary difference between the new gpt-3.5-turbo-instruct and its predecessor is its task-oriented approach. While the older version was more conversational, the new model is less chatty and operates in a manner that prioritizes following instructions efficiently, eliminating the need for additional prompting techniques.
Conclusion
Thus, the introduction of gpt-3.5-turbo-instruct by OpenAI signifies progress in AI language models, highlighting its focus on task-oriented efficiency and instruction-following. The model has the potential to benefit several applications. It includes not just content generation and information retrieval but also promises users a more efficient and dependable AI experience.
