LLM Apps development
Large language models are easy to demo and hard to ship. We build LLM features that hold up in production: the right model for the job, prompt and context engineering, fine-tuning where it pays, and evals plus monitoring so quality is measured, not guessed.
In short
LLM Apps, at a glance
- Frontier or open models chosen per task, balancing capability, cost and latency.
- Caching, routing and smaller models keep latency and token bills under control.
- Structured outputs, validation and fallbacks turn a flaky demo into a dependable feature.
- RAG and context engineering connect models to your knowledge, not just their training.
Why LLM Apps
LLM Apps in production.
A clever prompt makes a great demo; a reliable feature needs engineering. We treat LLM work like software: versioned prompts, structured outputs, context pipelines, fallbacks and a test suite that scores quality on every change.
We pick models pragmatically — frontier APIs where capability matters, smaller or open models where cost, latency or privacy do — and fine-tune only when evals prove it beats a well-engineered prompt.
Right model, right job
Frontier or open models chosen per task, balancing capability, cost and latency.
Fast and affordable
Caching, routing and smaller models keep latency and token bills under control.
Reliable outputs
Structured outputs, validation and fallbacks turn a flaky demo into a dependable feature.
Grounded in your data
RAG and context engineering connect models to your knowledge, not just their training.
Wired into product
LLM calls become typed services with the same rigour as the rest of your stack.
Eval-driven quality
Every prompt or model change is scored against real cases before it ships.
How we engineer
with LLM Apps.
How we work
Senior engineers, accountable to outcomes. Every change typed, reviewed and tested.

LLM Apps questions, answered.
Still unsure if LLM Apps is right for your project? A senior engineer will tell you straight on a free call.
It depends on the task. Frontier APIs like Claude or GPT win when raw capability matters; smaller or open models (Llama, Mistral) win on cost, latency or when data must stay in your environment. We benchmark options against your task and recommend honestly.
Usually not at first. A well-engineered prompt with good context beats a mediocre fine-tune and is far cheaper to maintain. We fine-tune when evals show a clear, durable win, often to make a smaller model match a bigger one on your specific task.
We treat them like software: structured, validated outputs, fallbacks for failures, version-controlled prompts, and an evaluation suite that scores quality on every change. In production we monitor quality, cost and drift.
Caching repeated work, routing easy requests to cheaper models, trimming context, and using smaller fine-tuned models where they suffice. We track spend on dashboards so cost never surprises you.
Yes. Most of our LLM work is embedding features into existing products: an assistant, smart search, drafting, classification or extraction, shipped as typed services that fit your current architecture.
