Request: Allowlist Access for Gemini 3.1 Fine-Tuning on Vertex AI (Google for Startups Member)

Hi team,

I’m the founder of TypeScience, an AI personality-classification platform, and a current Google for Startups Cloud Program member.

We’re actively building on Vertex AI and have already completed a supervised fine-tuning run on Gemini 2.5 Flash using our own labeled multimodal dataset and structured JSON outputs. Our pipeline, evaluation setup, and cloud environment are already in place, and we are continuing to iterate on model quality.

I’m reaching out to ask whether Gemini 3.1 fine-tuning on Vertex AI is currently available through a preview, allowlist, or any limited-access path for startups already building on Vertex AI.

Our use case is a domain-specific multimodal classification workflow with nuanced behavioral labels, and we’d like to evaluate whether access to Gemini 3.1 tuning could materially improve performance relative to our current tuned Gemini 2.5 baseline.

If there is a specific application process, allowlist path, or team we should contact for this, I’d really appreciate the guidance.

Thanks,
Austin
