AI app development that ships production, not demos.

We build AI — LLM apps, RAG systems, AI agents, and generative AI development work — with real pipelines, cost control, and grounding from day one. Not prototypes that break the moment real users show up.

Why Entalogics for AI

Four things every AI product actually needs.

Most AI app development projects break the same way: no evals, raw prompts, runaway cost, vendor lock-in. As an AI development company, we solve these four problems first — before writing a single feature.

Eval first01

Eval pipeline before launch.

If AI output isn't measured, it's guessed. We build the eval dataset before we release the first prompt, so cost, accuracy, and vendor tradeoffs are decisions you control — not surprises you discover in production.

RAG default02

RAG architecture, not raw prompts.

Grounded answers with source citation. Your data stays in your control, and every response traces back to a document, not a hallucination.

Cost-aware03

Cost controls from day one.

Token spend modeled before launch. Tiered fallbacks stop cheap requests from routing to expensive models by default.

Your IP04

Your models, your data, your IP.

Deploy on your own infrastructure. No lock-in to a single provider — self-hosted, VPC, or hybrid, on your terms.

When to use what

The decision matrix
every AI buyer wants.

These are the questions every founder asks before signing. Here are the answers we give — the same ones we'd give on a discovery call, before any formal AI consulting engagement begins.

Q01RAG, fine-tune, or prompt engineering?
RAG

Your knowledge base is the model's brain. Best when facts, freshness, or auditability matter — no retraining needed as your data changes.

Fine-tune

The behaviour you want the model reinforced with 1,000+ high-quality examples. Best for tone, voice, or a specific task the model keeps getting wrong.

Prompt engineering

Single-shot tasks where the model already knows the domain. Cheap to build, quick to test, slower to scale.

Q02Frontier APIs, open-source, or self-hosted?
Frontier APIs

Best quality-to-time ratio for early builds. Zero infrastructure to manage. Vendor risk is the tradeoff.

Open-source

Llama, Mistral, or open reference models you fully control. Fine-tune freely and avoid per-token billing.

Self-hosted

Regulated data or air-gapped environments. Deploy on your own VPC, at Azure, GCP, or bare metal.

Q03Is AI the right tool here, or is software better?
Reach for AI

Fuzzy inputs, language-heavy tasks, ambiguity, agent-style rule interpretation.

Stay traditional

Deterministic logic, exact arithmetic, deterministic compliance rules, and rule-code that's easier to test.

Mixed approach

AI at the language edge, traditional code for the math and compliance-heavy core.

Quality system

How we evaluate
AI output, in writing.

An AI product is only as good as the evals around it. Five things we do on every AI development services engagement — not as a sales line, as a checklist before launch.

01
Automated evals
Test datasets built with ground-truth answers. Every pull request runs the suite. Regressions get caught before they ship, not after a customer complains.
02
Grounding checks
Every client claim is matched back to source documents. Hallucinations get flagged, not shipped.
03
Human-in-the-loop
Higher-stakes outputs go through a review queue. Reviewer feedback becomes the next eval dataset — so the model improves on your actual usage, not a generic benchmark.
04
A/B model swaps
New models get tested in parallel, off the live traffic path. Model upgrades and vendor migrations are measured against the current baseline, not assumed to be better.
05
Live dashboards
Accuracy, latency, cost, and refusal rate — tracked and visible, not buried in a PDF after the fact.

Engagement shape

From prompt to
production in four phases.

A typical AI development engagement, end to end. Evals come before features, monitoring comes before scale.

W01–02
Discovery & eval design
Define success metrics, build eval sets, select providers, estimate cost per query. If you have a messy dataset, this is where we shape it.
W03–06
Prototype & validate
Working AI features against real usage data, tested against eval sets. Cost-per-request measured at this stage, not after launch.
W07–10
Production & harden
Error handling, monitoring, rate-limiting, cost controls, edge-case handling. This is the stage where most demo-ware breaks.
Ongoing
Scale & improve
Model upgrades get tested and re-benchmarked in CI, prompt regressions caught in review. The product gets better without getting riskier.

ENGAGEMENT

Three ways to
work with us.

No hourly retainer that bills for 'thinking time.' Pick a lane that matches your stage — everything is fixed-scope or transparently staffed.

FAQ

Things every
founder asks.

OpenAI, Anthropic Claude, Gemini, and open-source models like Llama and Mistral through HuggingFace or Ollama. Model choice depends on your data sensitivity, budget, and latency needs — we scope this on the discovery call before any AI development work starts.
Every engagement ships with an eval pipeline before the first feature goes live. Grounding checks, human review on high-stakes output, and live dashboards for accuracy, cost, and latency — covered under "How we evaluate AI output" above.
Only if you choose a frontier API. If your data can't leave your infrastructure, we build with self-hosted or open-source models instead — see the decision matrix above for the tradeoffs.
RAG (retrieval-augmented generation) grounds AI answers in your own documents or database, instead of relying on the model's training data alone. You need it if your answers have to reflect facts that change — inventory, policies, support docs, pricing.
An MVP AI build typically ships in 6–10 weeks. Embedded AI engineer engagements run month to month. Compliance-grade builds run longer, based on audit and infrastructure requirements — see "Three ways to work with us" above.
Yes. Most of our AI integration services work is exactly this — adding LLM features, an AI agent, or a RAG layer into an existing codebase without a rebuild.
It depends on the shape of the build. Our MVP package is fixed-scope for a 6–10 week build. Embedded AI engineers are staffed month to month. Compliance-grade builds are scoped after an architecture review. Book a call and we'll tell you which lane fits, and roughly what it costs, before you commit to anything.
