Allowlist request: gemini-3.1-flash-lite supervised tuning on Vertex AI

Gemini API
1

Hi Google team,

Requesting allowlist access to supervised fine-tuning for gemini-3.1-flash-lite on Vertex AI.

The base model works for inference in our project, but it does not show up as a tunable base model in Vertex AI Studio → Tuning (only the 2.5 models appear). I understand 3.1 tuning is currently gated/preview, so I’d like our project allowlisted.

Project details:

  • Project ID: talent-stream-app
  • Region: us-central1
  • Vertex AI API enabled: yes
  • Billing: active
  • Model requested: gemini-3.1-flash-lite (supervised tuning)

Use case: a latency-sensitive, real-time interview. We’ve exhausted prompt-level optimization on Flash-Lite and want to fine-tune it to better match style and decisions. SFT dataset (JSONL, train/validation split) is ready.

Thanks!
