AI harness & LLM apps

LLM application development that holds up in production.

Monocerix delivers LLM application development for teams moving AI from demo to production. We engineer the AI harness around the model: the tools it can use, the data it retrieves (RAG), the guardrails that keep it safe, the evals that prove it works and the monitoring that keeps it working.

Demo vs production

The model is 10%. The harness is the rest.

Generative AI development is easy to demo and hard to ship. In production, models face messy inputs, edge cases, cost limits, latency targets and real consequences when they are wrong.

An AI harness is the engineering around the model that makes it dependable: structured prompts, retrieval, tool permissions, validation, fallbacks, evals and observability.

  • Grounded: retrieval from your approved data
  • Controlled: tool permissions and AI guardrails
  • Proven: LLM evals on real test sets
  • Observable: tracing, cost and quality dashboards
What you get

What we engineer around the model.

RAG pipelines

Ingestion, chunking, embeddings, hybrid search and re-ranking. See RAG development.

Tools & agents

Typed tools with permissions, so agents act safely in your systems.

MCP servers

Expose your systems to AI assistants through the Model Context Protocol. See MCP servers.

AI guardrails

Input and output checks, PII handling, policy rules and safe fallbacks.

LLM evals

Test sets, automated scoring and regression checks before every release.

Observability

Tracing, cost, latency and quality monitoring in production.

Model strategy

The right model per task across Claude, GPT, Gemini and open models.

Security & privacy

Data minimization, access control, audit logs and regional hosting.

Continuous improvement

Feedback loops that turn failures into better prompts, data and tests.

Thailand

PDPA-aware data handling and Thai-language evals and guardrails.

Buyer guide

LLM application development: common questions.

Why do AI pilots fail?

Usually not because of the model. They fail because nobody defined what good looks like, there was no test set, retrieval returned the wrong context, or the system had no way to catch and recover from mistakes.

What does it cost?

Taking an AI prototype to production typically costs $8,000 to $40,000 depending on data, integrations and risk. With us, AI harness work starts from $700 for clients outside India.

Fine-tuning or RAG?

For most business use cases, retrieval (RAG) with good prompts and tools beats fine-tuning: it is cheaper, easier to update and easier to audit. Fine-tuning helps for style, format or very specialized tasks.

Starting price: $700 (about AED 2,570) for clients outside India. Every project then gets a written, itemized quote. See all starting prices.

Ask a question
What is an AI harness?

The engineering around a language model that makes it reliable in production: retrieval, tools, guardrails, evaluation and monitoring.

Which models do you work with?

Claude, GPT, Gemini and open models such as Llama and Mistral, chosen per task.

Can you fix our existing AI app?

Yes. We start by building an evaluation set, measure where it fails and fix the biggest causes first.

How do you stop hallucinations?

By grounding answers in retrieved sources, requiring citations, validating outputs, limiting scope and routing low-confidence cases to people.

Can the AI run in our own cloud?

Yes. We deploy in your cloud account and region, and can use private model endpoints.
