Fine-tuning with the Gemini API

With the deprecation of Gemini 1.5 Flash-001 in May 2025, we no longer have a model available which supports fine-tuning in the Gemini API or AI Studio, but it is supported in Vertex AI.

We don't have immediate plans to bring fine-tuning support but would love to hear from you on our developer forum if fine-tuning is important to your use case.
