AI Platforms: MLOps, LLMOps and the AI Control Layer

Give every team a secure, standardized way to build, deploy and operate models, prompts and agents, with central visibility over quality, cost and risk.

One Foundation for Every AI Workload

As AI use grows, so does sprawl: different teams calling different model providers with their own API keys, models deployed by hand from notebooks, prompts hard-coded in applications and no consistent view of who is using what. Each new use case rebuilds the same plumbing for data access, deployment, logging and security, and leadership cannot see total spend or enforce policy. The result is slow delivery, duplicated cost and avoidable risk.

Hanoi Technology designs and builds AI platforms that solve this once. We combine MLOps for classical models, LLMOps for prompts, retrieval and agents, and a central AI control layer that routes requests, enforces guardrails and tracks usage. Built on your cloud and data platform, it gives product teams self-service paved roads while platform, security and finance teams gain the oversight they need.

The Challenge

The Hidden Costs of AI Without a Platform

Problems that appear once more than a handful of AI solutions are in production.

Fragmented Tools and Duplicated Work

Every team assembles its own stack for experiment tracking, deployment and vector search. Knowledge is not shared, and maintaining many bespoke pipelines consumes engineering capacity.

No Control over Model Access and Spend

API keys for commercial models are scattered across code and teams. Nobody can enforce which models are allowed, set budgets or attribute costs to products and departments.

Inconsistent Safety and Compliance

Prompt injection defenses, PII filtering and content moderation are implemented differently, or not at all, in each application. Auditors cannot get a consistent record of AI decisions.

Slow, Risky Releases

Without automated testing and versioning for models and prompts, updates are manual and regressions reach users. Teams become reluctant to improve solutions that are already live.

Business Value

Benefits of a Well-Designed AI Platform

Faster Time to Production

Templates, shared services and automated pipelines let teams move from prototype to production in a fraction of the time. New use cases reuse proven building blocks.

Central Governance, Local Freedom

Policies for models, data and safety are enforced once at the platform level, while product teams choose what to build and when to release.

Transparent, Controlled Costs

Every model call and training job is attributed to a team and use case. Budgets, rate limits and smart routing keep spend predictable.

Model and Vendor Flexibility

An abstraction layer lets you switch between OpenAI, Anthropic, Google, open-weight and fine-tuned models without rewriting applications.

Reliable Quality in Production

Evaluation suites, regression tests and monitoring catch accuracy, drift and latency problems before users notice them.

Complete Auditability

Lineage for data, models and prompts, plus logs of inputs, outputs and approvals, provides the evidence needed for audits and incident investigations.

Treat AI Like Any Other Production Software

Models and prompts are code with extra uncertainty. They deserve version control, automated tests, staged releases, observability and rollback just like your other critical systems. A platform makes those disciplines the default rather than the exception.

Use Cases

AI Platform Scenarios

Situations where organizations invest in a shared AI platform.

Consolidating Model Access Across Departments

An enterprise with dozens of teams calling commercial LLMs directly introduces an AI gateway. Spend is attributed per team, approved models are enforced and keys disappear from code.

Standardizing ML Deployment

A data science team that deploys models manually adopts automated pipelines and a registry. Releases become routine, reproducible and auditable.

Multi-Model Routing for Cost Control

A SaaS company routes simple requests to smaller, cheaper models and complex ones to frontier models. Costs drop without visible loss of quality for users.

Secure Enterprise Agent Platform

An organization deploying AI agents needs consistent tool permissions, approval steps and action logging. A shared agent runtime enforces these controls for every agent.

Regulated Model Lifecycle

A financial services firm needs evidence of validation, approval and monitoring for every model. The platform captures lineage and approvals automatically.

Self-Service RAG for Product Teams

Product teams need to add document search to their apps. A shared ingestion, embedding and retrieval service lets them do it in days rather than months.

AI Platforms FAQ

What is the difference between MLOps and LLMOps?

MLOps covers the lifecycle of models you train yourself: data and feature pipelines, experiment tracking, model registries, automated deployment and drift monitoring. LLMOps addresses applications built on large language models, which add new concerns such as prompt versioning, retrieval pipelines, evaluation of open-ended outputs, guardrails, tracing of multi-step agents and token cost management. A modern AI platform supports both, sharing common foundations like identity, observability and CI/CD.

What is an AI gateway and why do we need one?

An AI gateway is a central service through which all applications access language models and other AI services. It handles authentication, routes requests to approved providers, applies rate limits and budgets, caches repeated requests, enforces guardrails and records usage for cost attribution and audit. Without it, every application must solve these problems independently, and leadership cannot see or control AI usage across the organization.

Should we build our platform or buy one?

Usually a combination. Cloud providers and vendors such as Databricks offer strong managed components, and open-source tools like MLflow and LiteLLM fill specific gaps. Building everything yourself is rarely justified, but neither is buying a single product that locks you in. We evaluate your requirements, existing investments and team skills, and recommend the mix that minimizes custom code while keeping you flexible.

How long does it take to stand up an AI platform?

A minimum viable platform supporting two or three lighthouse use cases is typically ready in eight to twelve weeks, depending on how mature your cloud foundation, networking and identity setup already are. We deliberately avoid building a large platform before anyone uses it. Further capabilities are added incrementally as teams onboard, guided by actual demand and measured adoption.

How do you secure AI workloads on the platform?

We apply defense in depth: private networking to model endpoints, centralized secrets management, identity-based access for users and services, data classification and masking before data reaches models, guardrails against prompt injection and data leakage, and full logging of inputs and outputs where policy allows. For agents, tool access is scoped by role and sensitive actions require human approval. Security reviews and red-team tests are part of every release.

Can the platform work with our existing data platform?

Yes. We design the AI platform as an extension of your data foundation rather than a separate island. It can read curated data from Databricks, Snowflake, BigQuery, Microsoft Fabric or your data lake, respect existing access controls and lineage, and write predictions and results back. This keeps governance consistent and avoids copying sensitive data into yet another system.
