Most AI projects die in the gap between a slick demo and a system real users can depend on. Our AI development services exist to close that gap: we take your idea and turn it into reliable, production-grade software — not a prototype that breaks the first time a customer touches it.
What our AI development services include
- AI & LLM apps — custom products built on OpenAI, Claude, Gemini, and open-source models
- RAG systems — chat and search over your own data, with citations (see RAG vs fine-tuning)
- AI agents & automation — multi-step workflows that take real actions
- Backends & APIs — FastAPI, Django, and NestJS, async and fully typed
- Evals, guardrails & monitoring — so your AI behaves in production, not just in the demo
Why teams choose Kortex Labs
You work directly with the senior engineer building your product — no juniors learning on your budget, no account-manager wall. We scope the simplest architecture that solves the problem, quote a fixed range up front, and hand over 100% of the source code and IP. We've shipped real production systems: large-scale data pipelines across 27 countries, real-time event platforms, and voice-first AI products.
How much do AI development services cost?
It depends on scope, but most projects start in the $8,000–$30,000 range for a focused build, with larger platforms going higher. We give a fixed quote after a free scoping call — see the full breakdown in how much it costs to build an AI app.
