Gemini Integration & Fine-Tuning

Production Gemini integrations, grounded and optimised.

We build production-grade Gemini 2.0 integrations on Vertex AI — with Google Search grounding, enterprise data grounding, function calling, fine-tuning, and token cost controls baked in from day one.

How It Works

From model selection to production in four weeks.

01Week 1

Integration Architecture

We design the integration foundation — selecting the right Gemini model (Flash vs Pro), defining grounding strategy with Google Search or enterprise data, and architecting function calling and tool use patterns for your use case.

  • Gemini Flash vs Pro selection for your workload
  • Grounding strategy — Google Search vs enterprise data
  • Function calling and tool use architecture design
02Weeks 2–3

Build & Evaluate

We build the integration end-to-end — wiring the Vertex AI API, configuring grounding, building the evaluation pipeline, and applying safety filters before any production traffic touches the model.

  • Vertex AI Gemini API integration and testing
  • Grounding configuration and evaluation pipeline
  • Safety filters and content moderation setup
03Week 4+

Deploy & Optimise

We deploy to production, wire up token cost monitoring, and run prompt optimisation cycles to maximise quality-per-dollar as usage scales across your team or product.

  • Production deployment on Vertex AI
  • Token cost monitoring and alerting
  • Prompt optimisation and model evaluation cycles

What's Included

Every layer of a production Gemini integration.

Gemini Model Selection & Evaluation

Rigorous benchmarking of Gemini Flash, Pro, and Ultra variants against your actual workload — latency, accuracy, cost, and context window — so you pick the right model from day one.

Grounding with Google Search

Connect Gemini to live Google Search results using the Vertex AI Grounding API, dramatically reducing hallucinations and keeping responses current without manual knowledge-base maintenance.

Enterprise Data Grounding via Vertex AI Search

Ground Gemini responses in your proprietary documents, databases, and knowledge bases using Vertex AI Search datastores — keeping sensitive data within your GCP environment.

Function Calling & Tool Use

Build Gemini integrations that call external APIs, execute database queries, trigger workflows, and use tools — turning Gemini from a text generator into an action-taking agent.

Fine-Tuning on Proprietary Data

Supervised fine-tuning of Gemini models on your domain-specific data using Vertex AI — improving response quality and domain knowledge without sharing your data with Google.

Token Cost Optimisation

Systematic prompt compression, caching strategy, and model tier selection to reduce Gemini API spend by 30–60% while maintaining or improving response quality.

Who It's For

Is this engagement right for you?

Teams wanting to integrate Gemini into products

Engineering teams building Gemini-powered features into their SaaS products or internal tools — you need a production-grade integration with grounding, safety, and cost controls from the start.

Engineers replacing OpenAI with Google models

Teams migrating from GPT-4 or Claude to Gemini on Vertex AI — you need expert guidance on model parity, prompt adaptation, and cost optimisation during the transition.

Organisations with sensitive data needing enterprise grounding

Enterprises that cannot send proprietary data to external search APIs — you need Gemini grounded in your internal documents within GCP's VPC Service Controls perimeter.
