The OpenAI Fine-Tuning Interface offers four specialized methods to tailor models for industry-specific applications:
This interface allows developers to train models using proprietary data without exposing it via API requests, resulting in customized versions of base models - like GPT-5.2, GPT-5 mini, or o4-mini - that excel in niche areas. A unique Evaluation Flywheel ensures performance improvements by leveraging Python-based and model-based graders to assess the fine-tuned models against industry standards before deployment.
The interface simplifies the process of developing and managing prompts with features like versioning and rollback capabilities. Developers can publish drafts, update versions, and revert to previous iterations with a single click, all tied to a unified Prompt ID that always points to the latest version.
Dynamic prompt variables, such as {{user_goal}}, allow real-time data integration into standardized templates without altering the base structure. Additionally, the built-in Optimize tool fine-tunes prompts using dataset feedback. For enterprises handling large-scale workloads, the platform integrates seamlessly with tools like Weights & Biases to sync training metrics and logs automatically. Features like prompt caching can cut latency by up to 80% and reduce costs by as much as 75%.
Training costs vary based on the method and usage. SFT and DPO are charged by training tokens and epochs, while RFT for models like o4-mini costs $100.00 per hour of active compute time, with a cap of $5,000 per job. Hosting standard models adds $1.70 per hour, alongside per-token inference charges. Importantly, charges apply only to active training time, excluding time lost to queues or service interruptions.
Fine-tuning helps enterprises save on token costs by enabling shorter prompts with fewer examples. For instance, o4-mini inference costs $1.10 per 1 million input tokens and $4.40 per 1 million output tokens, making smaller fine-tuned models a cost-effective choice for specialized tasks compared to larger base models.
The interface also delivers advanced features tailored for enterprise needs. It supports regional deployments for data residency and offers Provisioned Throughput to guarantee performance for latency-sensitive operations. Models like GPT-5.2 can handle context lengths of up to 128,000 tokens, with training examples capped at 65,536 tokens. For regulated industries, the platform ensures structured outputs that comply with strict JSON schemas, enabling reliable data parsing and adherence to compliance requirements.
