OpenAI announced the ability to fine-tune its powerful language models, including both GPT-3.5 Turbo and GPT-4.
Fine-tuning allows developers to tailor models to specific use cases and deploy these custom models at scale. This move aims to bridge the gap between AI capabilities and real-world applications, ushering in a new era of highly specialized AI interactions.
Impressive results in early tests show that the finely tuned version of GPT-3.5 Turbo is capable of not only matching, but exceeding the capabilities of the base GPT-4 for certain narrow tasks. We have proven that.
All data sent and received through the Finetuning API remains the property of the customer, so sensitive information is kept safe and not used to train other models.
The introduction of tweaks has received a lot of interest from developers and enterprises. Since the introduction of GPT-3.5 Turbo, there has been an increasing demand for customizing the model to create unique user experiences.
Fine-tuning opens up a realm of possibilities across a variety of use cases, including:
- Improved maneuverability: Developers can now fine-tune their models to follow instructions more accurately. For example, companies that require consistent responses in a particular language can ensure that their models always respond in that language.
- Reliable output format: Consistent formatting of AI-generated responses is critical, especially for applications such as code completion and making API calls. Fine-tuning improves the model's ability to generate well-formatted responses and improves the user experience.
- Custom tone: Fine-tuning allows businesses to adjust the tone of the model's output to match their brand voice. This ensures a consistent and on-brand communication style.
One of the big benefits of the fine-tuned GPT-3.5 Turbo is its expanded token processing power. The ability to handle 4,000 tokens, double the capacity of the previous fine-tuned model, allows developers to streamline prompt sizes, leading to faster and lower cost API calls.
Fine-tuning can be combined with techniques such as prompt engineering, information retrieval, and function calls to achieve optimal results. OpenAI also plans to introduce support for function calls and fine-tuning with gpt-3.5-turbo-16k in the coming months.
The fine-tuning process involves several steps, including preparing data, uploading files, creating a fine-tuning job, and using the fine-tuning model in production. OpenAI is working on developing a user interface to simplify the management of fine-tuning tasks.
Tweak pricing consists of two components: initial training cost and usage cost.
- Training: $0.008 / 1,000 tokens
- Usage input: $0.012 / 1K token
- Usage output: $0.016 / 1K tokens
Introducing updated GPT-3 model – Babbage-002 and Da Vinci-002 – has also been announced, offering a replacement for existing models and allowing for fine-tuning for further customization.
These latest announcements highlight OpenAI's dedication to creating AI solutions that can be customized to meet the unique needs of enterprises and developers.
