SOLUTIONS / STARTUPS

Add AIto your product.

Start with the model you need today and keep the freedom to change tomorrow. Explore open-weight models, deploy inference, and scale your product without managing GPUs, servers, or integrations with multiple providers.

STARTING IS EASY

The hard part starts when your product works.

An API may be enough to launch an MVP. Then users arrive, volume grows, and decisions appear that did not exist at the beginning.

The model no longer fits

You need more quality for some tasks, lower latency for others, and perhaps a different model for vision, code, embeddings, or generation.

The bill starts to matter

What looked cheap with a few users changes when every request means more tokens, context, and inference.

You want open-weight models

Finding a model is easy. Running it reliably in production means GPUs, runtimes, deployments, and operations.

Your app depends too much on one provider

Changing models should not mean rebuilding your product's inference layer.

You now process real data

Prompts, documents, internal information, and customer data turn privacy, isolation, and residency into architecture decisions.

Your team is still small

Every hour spent maintaining AI infrastructure is an hour not spent building the product.

QDivZero brings models, compute, deployments, data, and security together in one platform. Start with what you need today and add capabilities when your product needs them, without adding providers and tools to your stack.

AI INFRASTRUCTURE FOR STARTUPS

Grow in product, not in complexity.

01MODELS

Change models without changing your product.

Use public models selected by QDivZero, explore thousands of open-weight models for text, code, reasoning, vision, image, video, audio, voice, and embeddings, or deploy your own private and fine-tuned models. Try and deploy them through an OpenAI-compatible API.

Explore models
02DEPLOYMENTS

Deploy models. Not GPUs.

Deploy open-weight models from Hugging Face or your own private and fine-tuned models. QDivZero identifies their requirements, finds compatible compute across providers, prepares the inference environment, and keeps the endpoint ready to use.

Deploy a model
03COSTS

Optimize when every request starts to count.

With QDivZero, you can use balance, an Unlimited Basic subscription, or both in the same account. Public Models deduct balance according to input and output tokens, dedicated deployments deduct it for active compute time, and Unlimited Basic provides Qwen 3.8 27B for a fixed monthly fee without using balance.

04ROUTING

Use the right model for every task.

Combine LLMs and distribute requests by cost, latency, or quality. Configure alternatives to keep your application running when a model is unavailable.

Discover LLM Model Routing
05DATA

Connect your models to what your company knows.

Use embeddings, semantic search, and RAG to retrieve information from documents, products, customers, or internal knowledge during inference.

Build with your data
06SECURITY

Protect what reaches your models.

LLM Firewall analyzes requests before inference and applies policies against prompt injection, jailbreaks, sensitive data, abuse, and disallowed content.

FOR SMALL TEAMS

Your development team should not need an AI infrastructure team.

If three, five, or ten of you are building a product, you probably do not want to spend part of the team maintaining inference runtimes, finding available GPUs, integrating providers, and building routing, observability, and security around models.

Frequently asked questions about AI infrastructure for startups

Practical answers about open-weight models, Hugging Face deployments, GPU infrastructure, inference costs, RAG, security, and OpenAI-compatible APIs.

What AI infrastructure does a startup need to move from MVP to production?+

Taking an AI MVP to production requires reliable model serving, compute allocation, cost control, data connections, and request security. QDivZero brings models, deployments, routing, and security into one layer so the team can scale the product without building and maintaining the entire AI infrastructure stack separately.

How do I deploy a Hugging Face model to production without managing GPUs?+

Choose a compatible Hugging Face model and define the region and workload requirements. QDivZero finds suitable GPU compute across providers, prepares the inference environment, and creates an endpoint to serve the model, without requiring you to configure servers, drivers, or runtimes manually.

What is the difference between an AI API and an open-weight model?+

An AI API provides a model already hosted by a vendor and usually limits your choice to its catalog. An open-weight model gives you control over the architecture and execution environment, but it requires compute and inference infrastructure. QDivZero provides that operational layer while keeping a stable API integration.

When does dedicated GPU inference make sense for an LLM?+

Dedicated compute is often useful when traffic is sustained, predictable latency matters, or you need stronger isolation and operational control. Active compute time is prorated by the second and deducted from balance instead of being charged per processed token. In the same account, you can keep balance for Public Models and activate Unlimited Basic with Qwen 3.8 27B for a fixed monthly fee.

How can I reduce LLM inference costs as my product scales?+

Start by measuring cost per task rather than token price alone. Reserve the most capable models for complex requests, route simpler work to efficient models, remove unnecessary context, and compare dedicated compute. LLM Model Routing can distribute requests by cost, latency, quality, and availability.

Can I switch from OpenAI to an open-weight model without rebuilding my app?+

Yes. QDivZero provides an OpenAI-compatible API, allowing you to keep the familiar request format while changing the model behind the endpoint. This reduces integration work when testing an open-weight LLM, moving a workload to another provider, or combining several models in one product.

How do I use multiple LLMs in the same application?+

LLM Model Routing brings multiple models behind one access layer and decides which one should handle each request. Rules can consider task type, cost, latency, or quality and define fallbacks when a model is unavailable. Each workflow can use the right LLM without creating a separate integration.

How do I build a RAG system with proprietary documents and data?+

A RAG system turns content into embeddings, indexes that information, and retrieves relevant passages before generating an answer. QDivZero lets you combine embedding models, semantic search, and LLMs to query documentation, catalogs, or knowledge bases with company-specific context.

How do I protect an LLM against prompt injection, jailbreaks, and data leakage?+

Security policies should run before a request reaches the model. LLM Firewall analyzes prompts and responses for prompt injection, jailbreaks, sensitive data, abuse, and disallowed content. Depending on the policy, a request can continue, be blocked, modified, or recorded for audit.

Can I deploy AI models in Europe and control data residency?+

Yes, when the selected deployment and provider offer the required region. Choosing where a model runs can keep inference close to users and support internal data location, privacy, or residency requirements. Region selection should be evaluated together with the model, compute, and project policies.

How do I scale an AI application without hiring an infrastructure team?+

Define the model, region, and workload requirements; QDivZero finds compatible compute, prepares the deployment, and keeps the endpoint available. You can add routing, data retrieval, and security as the product needs them, without building an internal MLOps platform for every new capability.

How can I avoid AI model and vendor lock-in?+

Keep a provider-independent access layer instead of spreading a proprietary API throughout the application. Open-weight models, multi-provider compute, and an OpenAI-compatible API let you test alternatives, move a workload, and configure fallbacks without rebuilding the core product logic.
