Custom LLM Applications.

Domain-tuned chat, copilots, and document workflows — shipped to production, not to a demo.

LLM apps that go to production differ from prototypes in unglamorous ways: prompt evals, latency budgets, fallbacks, observability, and a 5×9 SLA you can sign. We ship the boring 80% so the AI gets to actually do the job.

▣ What you get

Deliverables.

Every engagement ships these as concrete artifacts you own — not slides, not hand-waving.

01

Production app + UI

Web or in-app surface (Next.js / React Native / Slack / Teams) with auth, role-based access, and audit logs.

02

Prompt + eval harness

Versioned prompts, golden test sets, regression evals on every PR — so model upgrades don't silently break behaviour.

03

Inference layer

Routing across OpenAI / Anthropic / Gemini / Bedrock / open-weight, with caching, retries, fallbacks, and cost guardrails.

04

Observability

Per-request traces, token spend, hallucination flagging, user feedback loop — wired into Datadog / Honeycomb / your stack.

⌖ How we work

The engagement.

PHASE 011–2 weeks

Spec & guardrails

Lock the user surface, the eval criteria, the latency / cost budget, and the failure-mode catalogue. No code yet.

PHASE 023–5 weeks

Build

Iterate on prompts, retrieval, and UI in parallel — daily evals, weekly demos, your team in the loop.

PHASE 031–2 weeks

Harden

Load testing, red-teaming, SOC-2 / ISO checks, runbooks, and the on-call handoff to your ops team.

PHASE 04Ongoing

Operate

Optional retainer — model upgrades, drift monitoring, and quarterly cost-optimisation passes.

▤ Tools we use

Pragmatic stack.

Best-in-class where it matters; boring and battle-tested everywhere else.

? FAQ

Common questions.

Which model do you recommend?

It depends on the task — we'll route across models and pick per-call. Frontier models (GPT-5, Claude Opus) for high-stakes reasoning; smaller / open-weight for high-volume cheap stuff. The router is part of the deliverable.

Will you train a custom model?

Usually no. RAG + a strong base model beats fine-tuning for 90% of use-cases now. If genuinely needed, we'd engage our Fine-tuning service separately.

Can it run fully on-prem / in our VPC?

Yes — we deploy in your AWS / GCP / Azure account, or on-prem with vLLM / TGI. Used in BFSI and government scopes.

Do you provide the UI design too?

We can. If not, we'll work to your Figma. We don't ship undesigned admin-panel UIs.
