The highly anticipated fine-tuning feature for GPT-4o was officially launched on Wednesday, offering developers a powerful tool to optimize AI models for specific use cases. According to a recent report, organizations can now access 1 million training tokens per day for free until September 23.
Fine-tuning allows developers to customize GPT-4o using their own datasets, tailoring the AI’s responses to better suit their needs. Customization could significantly enhance performance across various applications, ranging from technical coding tasks to more creative endeavors like content generation. By adjusting the structure and tone of the model’s responses, developers can ensure that GPT-4o aligns with complex, domain-specific requirements.
One of the standout benefits of fine-tuning is its efficiency. Developers could achieve impressive results with dozen examples in their training dataset This approach offers a cost-effective solution for improving AI performance. The feature is particularly valuable for developers working on niche applications where off-the-shelf models may not meet all requirements.

The fine-tuning option is now accessible to all developers on paid usage tiers, providing flexibility across various projects. To start, developers could visit the fine-tuning dashboard, click “create,” and select “gpt-4o-2024-08-06” from the base model drop-down menu. The cost for fine-tuning training is set at $25 per million tokens, while inference costs $3.75 per million input tokens and $15 per million output tokens.
The early success of fine-tuning is already evident. Distyl, an AI solutions partner to Fortune 500 companies, recently secured the top position on the BIRD-SQL benchmark, a leading text-to-SQL benchmark. Their fine-tuned GPT-4o achieved an impressive execution accuracy of 71.83%. The model excelled in tasks such as query reformulation, intent classification, chain-of-thought processing, and SQL generation.
The launch of fine-tuning for GPT-4o is just the beginning of broader efforts to enhance developer model customization options. This new capability opens up a range of possibilities for optimizing AI performance across diverse domains. Developers are encouraged to take advantage of the free training tokens and explore the potential of fine-tuning their own projects.
