GPT-4o fine-tuning now available

AI Impact Summary

GPT-4o now supports fine-tuning, enabling domain-specific behavior by training the model on your labeled data via the OpenAI API. This opens new customization avenues for specialized tasks but requires data preparation, model versioning, and governance processes, along with attention to costs, latency, and monitoring of fine-tuned outputs. Plan a rollout with dataset curation, evaluation against benchmarks, and a rollback strategy to base models if results degrade. Expect changes to deployment patterns as teams shift from prompt-only prompts to versioned, fine-tuned configurations.
