OpenAI Introduces Custom Fine-tuning for GPT-3.5 Turbo Model

OpenAI has exciting news for businesses and developers as they unveil the addition of fine-tuning capabilities to their popular GPT-3.5 Turbo model. This update is targeted at enabling the creation of tailored and supervised products that excel in specific tasks. According to OpenAI, a fine-tuned iteration of the GPT-3.5 Turbo model can not only match but also surpass the performance of advanced models like GPT-4. Let’s delve into the details of this custom fine-tuning feature for GPT-3.5 Turbo.

Customize GPT-3.5 Turbo with Fine-tuning on Your Knowledge Base

The introduction of fine-tuning offers users the power to customize the model according to their specific requirements. GPT-3.5 Turbo is already known for its impressive speed in drawing inferences, making it stand out in terms of performance. With the added fine-tuning support, developers can leverage this capability to create novel experiences. This could range from AI chatbots, documentation engines, and AI assistants to coding aides and much more. Essentially, you can now fashion a bespoke application for your business with the exact tone you desire.

It’s important to note that OpenAI designates specific GPT-3 series models, including “babbage-002” and “davinci-002“, for fine-tuning endeavors. However, there’s a tweak in the API endpoint, and you can find more about this updated endpoint on OpenAI’s official resources here. Among the key aspects of fine-tuning for GPT-3.5 Turbo is the meticulous evaluation of all training data through OpenAI’s Moderation API and the GPT-4 fueled moderation system. This process aims to identify and eliminate any unsafe training data that might violate OpenAI’s safety standards.

OpenAI underlines that none of the private training materials will be employed to train OpenAI models. Furthermore, GPT-3.5 Turbo’s current capability stands at handling 4k tokens in one go. However, an extended context length of 16k tokens and function calling support are slated to arrive later this fall.

Regarding the cost, refining the GPT-3.5 Turbo model through fine-tuning is priced at $0.0080 for every 1000 tokens during the training phase, $0.012 per 1000 tokens for input usage, and $0.016 per 1000 tokens for output usage. While the cost may be a tad higher than the Davinci and Babbage models, the superior results you can achieve through the fine-tuned version of GPT-3.5 Turbo make it a compelling choice.

Ultimately, OpenAI’s introduction of custom fine-tuning for GPT-3.5 Turbo opens up a world of possibilities for tailored AI solutions that cater precisely to your needs.
