LLM Integration
Services
that survive the next model release.

We build RAG systems, AI agents, chatbots, and LLM integrations that work in production — not just in demo videos. Eval-driven, observability-first, and architected so a provider's next model update doesn't break your roadmap.

What we build

Six AI systems
we ship into production.

We focus on the categories where evaluation is feasible — meaning we can prove the system works, not just hope it does. If your problem doesn't have a measurable success state, we'll tell you upfront.

Not on this list? We've also shipped voice agents, code assistants, and embedding-only retrieval pipelines. If LLMs are part of the answer, we can probably help.Tell us about it

The stack

Production AI tooling,
not last weekend's hackathon kit.

Anyone can wire OpenAI to a frontend. The hard parts come later — model switching, eval pipelines, observability, cost control. Below is what we reach for first, and why. We swap when there's a real reason.

Layer 01
Models & providers
A
Anthropic Claude
Reasoning, tool use, long context
DEFAULT
O
OpenAI
GPT-4.x · realtime · embeddings
G
Gemini
Vision-heavy + price-sensitive jobs
L
Llama / Qwen
Self-hosted · privacy · on-prem
B
Bedrock / Vertex
Enterprise compliance & governance
We default to Claude for agentic and reasoning-heavy work, OpenAI for realtime and where its embeddings still win, and self-hosted when there's a real privacy or cost reason. We architect provider-agnostic from day one so swapping models doesn't mean rewriting your app.

Short-term memory · caches
We don't reach for LangChain by default. For most production work, LangGraph + a thin Python or TypeScript layer wins on debuggability. Vector DBs are not a personality — pgvector handles most jobs until you genuinely outgrow it.

If you can't measure it, we won't ship it. Every project we run has an eval suite from week one and a tracing layer before the first deploy. This is what separates AI that improves over time from AI that decays the moment we hand it over.

Process

From feasibility check
to production AI in eight to fourteen weeks.

AI projects fail in week one or week ten. We front-load the failure modes — data audit, eval baseline, cost & latency targets — so by the time we ship, you know exactly what you're getting and what it costs to run.

Total timeline
8 – 14 weeks
01
WEEK 1

Discover

We pressure-test feasibility before we commit. If the problem doesn't have a measurable success state, we'll say so — not bill you for six months to find out.

  • You leave with
  • Data audit + feasibility memo
  • Success metrics + cost ceiling
  • Fixed-price proposal
02
2 – 3 WEEKS

Design & baseline

We build the eval set first. Then a naive prompted version. The baseline tells us how far simple gets us — and how much room there is to improve.

  • You leave with
  • Eval dataset + scoring rubric
  • Baseline prompted prototype
  • Architecture + model decision
03
4 – 8 WEEKS

Build

Iteration loops driven by the eval suite. Every change is measured. Cost and latency are first-class metrics, not afterthoughts. Friday demos with real numbers.

  • You leave with
  • Production-ready system
  • Eval scores hit target + CI
  • Cost-per-task + latency budgets
04
WEEK 1 – ONGOING

Launch & operate

Deploy with full tracing and a dashboard your team can actually use. Red-team probes in CI. Optional retainer to keep models, prompts, and evals current.

  • You leave with
  • Tracing dashboard + alerts
  • On-call playbook + runbook
  • Red-team probes in CI

Evals & safety

If you can't measure it,
we won't ship it.

Production AI without evals is hope wearing a deployment. Every Woyce build ships with eval pipelines, safety probes, and observability — the three things that turn a demo into a system you can trust.

01 / Evaluation

Eval pipelines that catch regressions

Curated eval datasets, automated scorers, and LLM-as-judge for the fuzzy stuff. Runs in CI on every prompt or model change.

02 / Safety

Red-team probes for the failure modes that matter

We test the failure modes you're worried about — and the ones you haven't thought of yet. Probes run in CI, not just at launch.

03 / Observability

Tracing, costs, and drift in one dashboard

Full request tracing, per-task cost tracking, latency budgets, and quality drift detection. Your team sees what's happening — and pays no surprise bills.

Why this matters: the difference between AI that ships and AI that stays

SIDE-BY-SIDE
Typical AI agency
  • "Looks great in the demo" — no eval suite to confirm
  • Discovers prompt injection bugs in production, post-launch
  • No idea what each request actually costs
  • Quality silently degrades when the model updates
  • Handover doc is the prompt and a Slack screenshot
Woyce
  • Eval scores on every change, gate in CI
  • Prompt injection & PII probes catch issues before launch
  • Cost-per-task tracked, alerts when it drifts up
  • Rolling quality dashboard catches drift early
  • Handover includes runbook, eval suite, and on-call playbook

Frequently asked questions

What is LLM integration?+

LLM integration means embedding large language models like GPT-4 or Claude into your business applications to power features like document Q&A, AI assistants, automated summarization, and intelligent search.

Can you integrate GPT-4 or Claude into my existing application?+

Yes. We integrate OpenAI GPT-4, Anthropic Claude, Google Gemini, and open-source LLMs into existing web and mobile applications using LangChain and direct API integrations.

What is RAG and do you build RAG chatbots?+

RAG (Retrieval-Augmented Generation) grounds LLM answers in your own documents and data using vector databases like Pinecone or Weaviate. Yes, we build RAG-based chatbots and Q&A systems.

Do you build AI agents?+

Yes. We build autonomous AI agents using LangChain Agents, LangGraph, and OpenAI Assistants that can use tools, browse the web, query databases, and complete multi-step tasks.
