AI products in production not demos.

We build production AI — LLM apps, RAG systems, agents, intelligent automation — with eval pipelines, cost controls, and grounding from day one. Not prototypes that break in production.

Why Entalogics for AI

Four things every
AI product actually needs.

Most AI builds break the same way: no evals, raw prompts, runaway cost, vendor lock-in. We solve those four problems first — before writing a feature.

Eval first01

Eval pipeline before launch.

AI output quality is measured, not assumed. We build the eval dataset before the first prompt and gate every release on it.

RAG default02

RAG architecture, not raw prompts.

Grounded answers with source attribution. Your data stays under your control; the model just retrieves and reasons over it.

Cost-aware03

Cost controls from day one.

Model selection matched to task. Token usage monitored. Tiered fallbacks for cheap-when-possible, expensive-when-required.

Your IP04

Your models, your data, your IP.

Deploy on your infrastructure if needed. No lock-in to a single provider. Self-hosted models when the contract demands.

When to use what

The decision matrix
every AI buyer wants.

Three questions every founder asks before signing. Here are the answers we give — the same ones we'd give on a discovery call.

Q01RAG, fine-tune, or prompt engineering?
RAGPICK FIRST

You have proprietary data the model has never seen. You need citations, freshness, or auditability. 9 out of 10 enterprise AI builds.

Fine-tuneRARELY

The behaviour can't be elicited by prompts and you have 1,000+ high-quality examples. Mostly: tone, format, domain-specific output style.

Prompt eng.START HERE

Single-turn tasks where the model already has the knowledge. Cheap to iterate, fast to ship. Often enough on its own.

Q02OpenAI / Anthropic, open-source, or self-hosted?
Frontier APIsDEFAULT

Best capability per dollar at low-to-mid volume. Anthropic Claude or GPT-4-class for hard tasks; cheaper tiers for the easy 80%.

Open-sourceAT SCALE

Llama / Mistral via inference providers when your volume makes API tokens expensive. Or when you need to fine-tune.

Self-hostedCOMPLIANCE

Regulated data, air-gapped deploys, or strict data-residency. We deploy on your VPC with Ollama, vLLM, or Triton.

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

Fuzzy inputs, language-heavy tasks, summarisation, classification with messy categories, agent-style tool use.

Stay traditionalNO

Deterministic logic, exact arithmetic, strict business rules, regulatory calculations. SQL and code do this better.

Mixed approachOFTEN

AI for the language layer, traditional code for the math and state. The boring answer is usually the right one.

Product shapes

Six AI product shapes,
one engineering bench.

The shapes of AI work we've shipped most often — each with the integrations we reach for first.

01
RAG applications
Knowledge-base Q&A, document search, support bots grounded in your data with citations.
PGVECTORPINECONELANGCHAIN
02
AI agents
Tool-using agents that take actions, not just answer questions. Run inside a sandbox with audit logs.
LANGGRAPHOPENAI-TOOLS
03
LLM-powered SaaS features
AI bolted onto existing products: summarisation, classification, generation.
VERCEL-AIRSC
04
Document intelligence
Invoice processing, contract analysis, medical-record extraction. OCR + LLM grading.
UNSTRUCTUREDAZURE-OCR
05
AI copilots & assistants
Domain-specific assistants for internal teams (legal, sales, support).
CLAUDEGPT-4TOOLS
06
AI-native mobile & web apps
Products where AI IS the core experience, not a bolted-on feature.

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 build — not as a sales line, as a checklist before launch.

01
Automated evals
Test datasets with ground-truth answers. Every PR runs the suite. Regressions block merge before they ship.
02
Grounding checks
Every cited claim is matched back to source documents. Hallucinations are flagged, not hoped against.
03
Human-in-the-loop
High-stakes outputs route to a reviewer queue. Reviewer feedback becomes the next eval dataset.
04
A / B model swaps
New models go behind a flag, get 5% of traffic, get measured against the eval suite before the cutover.
05
Live dashboards
Accuracy, latency, cost, and refusal rate tracked per route. Alerts fire on drift, not after the angry email.

Engagement shape

From prompt to
production in four phases.

A typical AI engagement, end-to-end. Evals come before features, monitoring before scale. No demo-ware that breaks in week three.

W01–02
Discovery & eval design
Define success metrics, build eval dataset, select models, estimate cost per query. By end of week 2 you have a measurable target, not a wish.
W03–04
Prototype & validate
Working AI feature with eval pipeline, tested against real data. Cost-per-request measured at the prototype stage, not after launch.
W05–08
Production & harden
Error handling, fallbacks, monitoring, rate limiting, cost controls, edge-case handling. The boring 60% that decides whether it survives.
W09+
Scale & improve
Model upgrades behind flags, prompt iteration tracked in CI, eval regression tracking, cost optimisation. The product gets better while it runs.

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-quote or transparently rated.

AI MVP buildShip fast

FAQ

Things every founder asks.

Don't see yours here? Ask us directly.

OpenAI (GPT-4o, GPT-4-turbo), Anthropic Claude (Opus, Sonnet, Haiku), Google Gemini, and open-source models via HuggingFace, Ollama, or vLLM (Llama, Mistral, Qwen). We pick the model per task, not the company — cheap when possible, expensive only when needed.
An eval pipeline before launch. Test dataset with ground truth, automated grading on every PR, grounding checks, human-in-loop review for high-stakes outputs, live dashboards tracking accuracy and drift. The full system is described in the eval section above.
Only if you want it to be. We use OpenAI / Anthropic by default because they're the highest quality at low-to-mid volume — both have zero-retention enterprise terms. For regulated industries we deploy open-source models on your VPC with no external API calls.
Retrieval-Augmented Generation: the model retrieves relevant chunks from your data before answering, and cites them. You need RAG when you have proprietary data the model has never seen, when you need source attribution, or when answers must reflect current information. 9 out of 10 enterprise AI builds use RAG.
MVP with eval pipeline: 6–10 weeks. Production AI feature in your existing product: 4–8 weeks. Enterprise AI with self-hosted models and compliance work: 10–14 weeks. We scope a fixed-price commitment at the end of week 1.
Yes — that's how a majority of our AI engagements start. Audit your codebase, scope the AI feature, build it behind a flag with an eval pipeline, ramp traffic to it. Your existing product keeps shipping while we work.
