Vertex - Migration to Gemini 2.0 Tunned Models

[dflorez]

Hi everyone,

as most of people using LLMs in Vertex I have received an email from google cloud advising for a compulsary upgrade for everyone using PaLM or Gemini 1.x to Gemini 2.0. In the email we are told

My doubt is, it doesn't specifically say that gemini-1.5-flash-001 fine-tunned models are going to be disconitinued, so, can I supposed they will continue to be available?

I attach next the email:

We're writing to inform you that starting April 2025, we’re discontinuing certain Generative AI models on Vertex AI and transitioning to Gemini 2.0 models.

We’ve put together some additional resources to help you understand the upcoming change.

What you need to know

The following models will be discontinued on the dates listed:

• April 9, 2025: PaLM, Codey, Gemini 1.0 Pro (including all fine-tuned versions), Select embeddings models
• May 24, 2025: Gemini 1.5 Pro 001, Gemini 1.5 Flash 001, Select embeddings models
• September 24, 2025: Gemini 1.5 Pro 002, Gemini 1.5 Flash 002

What you need to do

We encourage you to migrate all impacted models to the recommended Gemini 2.0 models immediately.

We’ve put together a list of impacted models in the table below:

Starting April 9, 2025, these models will be discontinued:

textembedding-gecko-multilingual@001	Migrate to text-multilingual-embedding-002 to avoid service disruptions

Starting May 24, 2025, these models will be discontinued:

Discontinued Models IDs	Recommended Action
gemini-1.5-pro-001	Migrate to gemini-2.0-flash to avoid service disruptions
gemini-1.5-flash-001	Migrate to gemini-2.0-flash-lite to avoid service disruptions
textembedding-gecko@003	Migrate to text-embedding-005 to avoid service disruptions

Starting September 24, 2025, these models will be discontinued:

Discontinued Models IDs	Recommended Action
gemini-1.5-pro-002 gemini-1.5-pro-002 (fine-tuned)	Migrate to gemini-2.0-flash to avoid service disruptions
gemini-1.5-flash-002 gemini-1.5-flash-002 (fine-tuned)	Migrate to gemini-2.0-flash-lite to avoid service disruptions

We've compiled these guidelines to assist you with the transition:

• Migrate from PaLM API to Gemini API on Vertex AI
• Migrate from Gemini 1.x API to Gemini 2.0 API on Vertex AI

ML Processing Compliance

If your current model relies on 1:1 ML processing region mapping and the required region is not yet available for a Gemini 2.0 model, please contact your account representative or Google Cloud Support.

For details on Gemini 2.0 regional availability, please refer to our documentation.

Hi @dflorez,

Welcome to Google Cloud Community!

At this time, there are no changes in the email regarding the discontinuation of specific Generative AI models on Vertex AI. Should the gemini-1.5-flash-001 fine-tuned models be included in the list of affected models, you may check the Vertex AI release notes for the latest updates.
