OpenAI is Fine-tuning for GPT-3.5 Turbo and GPT-4

OpenAI is unlocking new levels of specialization for its powerful AI models. Developers can now fine-tune both GPT-3.5 Turbo and GPT-4 to create custom versions tailored to their specific use cases.

This is very exciting as it allows businesses to bridge the gap between broad AI capabilities and specialized real-world applications. Early tests show fine-tuned GPT-3.5 Turbo can even surpass unmodified GPT-4 for narrow tasks.

The fine-tuning API also ensures data security as OpenAI says all information remains the property of the customer. (Hallelujah!) This has garnered major interest from developers since the launch of GPT-3.5 Turbo, as demand rises for unique customized experiences.

Fine-tuning Unlocks Exciting New Possibilities:

• Improved steerability – Developers can fine-tune models to follow instructions more accurately based on their needs.
• Reliable output formatting – Crucial for applications like code completion. Fine-tuning enhances proper formatting.
• Custom tone – Businesses can refine the tone to match their brand voice for consistent communications. (A quick reminder, you can train any Generative AI tools to adopt your – or your client’s – writing style.)

Token Pricing for Fine-Tuning:

GPT-3.5 Turbo’s expanded token handling allows larger prompt sizes, enabling faster API calls and cost savings.Pricing includes training costs and usage fees based on token volumes. Updated GPT-3 models have also been launched to replace existing ones and allow further customization. The pricing structure for fine-tuning comprises two components: an initial training cost and usage costs.

• Training: $0.008 / 1K Tokens
• Usage input: $0.012 / 1K Tokens
• Usage output: $0.016 / 1K Tokens

Prompt Engineering and Information Retrieval:

For best results, fine-tuning combines with other techniques like prompt engineering and info retrieval. Support for fine-tuning advanced models is coming soon.

The process involves data prep, file uploads, job creation, and deploying the tuned model. OpenAI is working on an interface to simplify fine-tuning management.

By empowering specialized tuning of its models, OpenAI is giving developers and businesses the tools to create truly tailored, effective AI solutions that meet their unique needs. The future is specialized.
