GPT-3.5 Turbo Instruct: An AI Instruction Model from OpenAI

OpenAI's GPT-3.5-turbo-instruct is a language model designed to excel in understanding and executing specific instructions efficiently. Unlike GPT-3.5-turbo, which is primarily geared towards engaging in conversations, GPT-3.5-turbo-instruct shines in completing various tasks and answering questions directly.

This new instruction language model is designed for efficiently following specific instructions, similar to the chat-focused GPT-3.5-turbo. It offers the same cost and performance as other GPT-3.5 models, all within a 4K context window, and it uses training data up to September 2021.

The Purpose of GPT-3.5 Turbo Instruct

The primary goal of GPT-3.5-turbo-instruct is to effectively follow instructions. It is not meant to be a conversational model but rather a task-oriented one. This distinction sets it apart from chat models and makes it exceptionally efficient at providing precise responses. Whether you need specific tasks accomplished or have questions that require precise answers, this model has got you covered.

Perhaps the most notable distinction between GPT-3.5-turbo and GPT-3.5-turbo-instruct is their approach to interactions. While GPT-3.5-turbo is conversational and chatty, the Instruct variant is more task-oriented. It excels in following instructions without requiring additional prompts, making it an invaluable tool for specific tasks and queries.

The following image shows an OpenAI-designed differentiation between the Instruct and Chat models. The difference can have implications on how prompts need to be written for both the models.

Instruct Models and Their Impact

OpenAI introduced Instruct models as a response to challenges seen in earlier models, such as hallucinations and the generation of inaccurate or harmful content. Instruct models were designed to reduce these issues and produce more truthful and safe responses.

Instruct models, including this new release, are a crucial foundation for the breakthroughs seen in ChatGPT, they are trained to follow instructions with human feedback using a powerful technique known as Reinforcement Learning from Human Feedback (RLHF). RLHF relies on human preferences as a reward signal to enhance the performance of language models. This is particularly crucial because the safety and alignment challenges being addressed are intricate and subjective, and they cannot be fully quantified through simplistic automatic metrics.

Key Features and Advantages

1. Efficient Instruction Following: The primary strength of GPT-3.5-turbo-instruct lies in its ability to follow instructions with precision and efficiency. Whether needed to complete a specific task, answer questions, or perform text-based functions, the model excels at promptly executing commands.
2.  Reduced Hallucinations and Toxicity: OpenAI's journey in developing instruct models began with the intent to reduce hallucinations and encourage more truthful and less toxic responses. By aligning the model's behavior with user expectations and instructions, GPT-3.5-turbo-instruct contributes to a safer and more reliable AI interaction.
3. GPT-3.5-turbo-instruct's Chess Capabilities: In a surprising turn of events, GPT-3.5-turbo Instruct has demonstrated its prowess in the world of chess. It achieved a remarkable Elo rating of around 1800, outperforming Stockfish Level 4 (1700) and putting up a respectable fight against Level 5 (2000). Notably, it played by the rules and even showcased clever strategies, including a cheeky pawn and king checkmate. This is a remarkable departure from earlier beliefs that GPT models couldn't play chess, a misconception that mainly pertained to chat-focused models
4. Replacing Older Models: OpenAI's introduction of "gpt-3.5-turbo-instruct" also involves retiring certain older models, including text-ada-001, text-babbage-001, text-curie-001, and the three text-davinci models. These older models will be phased out on January 4, 2024.
