Model-as-a-Service Platform

One API.
Every major AI model.

Call Claude, GPT, Gemini, DeepSeek, Qwen, Kimi and more through a single OpenAI-compatible API — with built-in smart routing, fallback and enterprise-grade guardrails, and your data kept compliant and local.

Why MaaS

Managing multiple AI models shouldn't be this hard

Integrating directly with every model vendor means duplicated work, scattered invoices, and a service that can break at any time.

Too many providers, too many keys

Every new model means another account, API key and invoice for your team to juggle.

Single points of failure

When your primary model goes down, so does your product — no fallback, no safety net.

Runaway costs

No visibility into token usage until the bill arrives at the end of the month.

Compliance & data sovereignty

Where do your prompts and data actually go — and does it meet PDPA?

Unified Model Catalog

One catalog. Every model that matters.

Each model comes with clear pricing, latency, context length and quality score. Switch models by changing one parameter — no code changes.

Platform Capabilities

An enterprise AI routing layer — not just token reselling

Six core capabilities, proven in production on Weitizen Router, that make AI calls as reliable as a utility.

PROVIDERS & KEYS

Providers & API key management

Manage every provider and credential centrally. Your apps never touch raw keys, and rotation takes one click.

CUSTOMERS

Customer management

Allocate usage and billing per downstream customer — built for reselling and B2B2C, so you can redistribute AI to your own clients.

GUARDRAILS

Guardrails

Content-risk detection, PII detection and jailbreak protection — enforced before requests ever reach a model.

LOGS & EVALUATION

Logs & evaluation

Every call is fully logged, and built-in evaluation tools compare how different models perform on your real business data.

BILLING & TEAM

Billing & team

Real-time cost dashboards, daily spend, requests-by-provider charts, plus role-based team access management.

OBSERVABILITY

Live health monitoring

Every provider's status and latency at a glance. Failover events are recorded automatically — issues get handled before your customers notice.

Enterprise · Data Sovereignty

A compliance-first foundation, built for local enterprises

In an era where data sovereignty is a boardroom issue, your AI foundation must be compliant from day one.

PDPA-ready

Aligned with Malaysia's PDPA (Amendment) Act 2024 and Singapore's PDPA. We help you run cross-border Transfer Impact Assessments.

Data residency

Keep your data in-country — meeting the requirements of finance, healthcare, government and other regulated industries.

Zero data retention

Your prompts and data are never retained — and never used to train any model.

Audit & access control

Full audit logs, RBAC, SSO and API-key rotation — ready for enterprise IT governance and security review.

Local team support

Trilingual (EN / CN / BM) local sales and technical teams — same time zone, no overnight waits.

Billing in MYR

Invoiced and settled in MYR — no overseas credit card needed, smoother procurement and expense flows.

Model Freedom

Western flagships + cost-efficient open models, freely combined

You don't have to choose between GPT/Gemini/Claude and DeepSeek/Qwen/Kimi/GLM. Use routing policy to spend every token dollar where it counts.

High-volume routine tasks → cost-efficient open modelsClassification, summarization, translation and extraction go to DeepSeek, Qwen, Kimi and friends — at a fraction of flagship cost.
Complex reasoning → flagship modelsComplex reasoning, critical decisions and high-value output stay with Claude, GPT and Gemini.
  • One API, automatic routing by scenario — no parallel model logic to maintain in your code.
  • Dramatically lower total token cost at the same quality bar.
  • Adjust routing policy anytime; new models are available the day they launch. No vendor lock-in.

Our own GPU compute base —
private inference on open models

We're building our own GPU compute foundation to deliver private, dedicated inference on open-source models — purpose-built for industries with strict data-sovereignty and compliance needs.

  • Data stays in-country — inference runs entirely on local compute
  • Dedicated capacity with better control over performance and cost
  • Plugs into the existing MaaS platform — same API, no new integration

Supply chain, inventory and demand forecasting — data-driven restocking and operations decisions.

FAQ

What buyers usually ask us

Is our data safe? Will it be used for training?

No. Weitizen operates on zero data retention — your prompts and business data are never retained, and never used to train any model. For regulated industries, we offer data-residency options so data stays fully in-country.

How is it billed?

Per-token usage, invoiced and settled in MYR — no overseas credit card needed. Enterprise plans (with volume discounts and SLA) are quoted by our sales team based on your usage scale.

Is it hard to migrate from our existing OpenAI / Gemini integration?

Very easy. The platform is fully OpenAI-API compatible — just point your base URL and API key at Weitizen. Near-zero code changes, and our technical team will assist with the migration.

Is there an SLA? How is availability guaranteed?

Enterprise plans include an SLA. The platform has smart routing and fallback chains built in: if a model or provider fails, requests switch to a backup model automatically to keep your product running.

Which models are supported?

Claude, GPT, Gemini, Grok, Kimi, DeepSeek, Qwen, GLM, Doubao Seed and more, continuously expanding. You can also talk to sales about adding specific models to your dedicated catalog.

What is the upcoming private inference service on open models?

We're building our own GPU compute foundation to offer private, dedicated inference on open-source models — data stays in-country, on dedicated capacity, with better cost control. Early-access requests are now open; contact our sales team for details.
