Vertex AI Tuning

Managed supervised fine-tuning and preference tuning for Gemini 2.0/2.5 Flash and Pro inside Google Cloud Vertex AI, covers text, image, audio, and document tuning with as few as 100 labeled examples. Picked when teams need Gemini-tier quality customized to a domain and want GCP-native data residency, IAM, and Vertex pipeline integration. The only path to fine-tune Gemini weights.

Google Cloud Vertex AI tuning for Gemini (docs live June 2026). Methods: supervised fine-tuning and preference tuning, across text/document/image/audio/video and function-calling. Proprietary managed Google Cloud service.

Adoption

not assessed

No disclosed usage figure for the Vertex Gemini tuning feature located this run. The Gemini app surface has 750M+ MAU but that is not the Vertex tuning service and cannot be attributed to this SKU; declining to assign a level rather than borrow the surface number.

Capability

4 medium confidence

4.0

Broad managed multimodal tuning (SFT + preference + function-calling, across modalities) over frontier closed Gemini models. Black-box (no scale/precision controls, no benchmark basis), so capped below the OSS scale definers; scored 4 on method+modality breadth, comparable to the OpenAI FT API.
