DigiEdze AI · Custom LLM & SLM Engineering

Use the Right Model, Own the Right Intelligence

Model choice is an architecture decision with cost, latency, sovereignty and lock-in consequences. We design a model strategy, often a portfolio, routed by task rather than a single vendor bet.

  • open-weight LLMs
  • SLMs
  • private models
  • specialised domain models

The Challenge

Impact for Business When Gone Wrong

One frontier model is used for every task, including the ones a small model would do better and cheaper.

A single vendor dependency becomes a pricing and continuity risk with no migration path.

Sensitive workloads are served by endpoints that cannot meet the data boundary they require.

What We Build

Custom LLM and SLM Capability Grid

Model selection framework icon

Model Selection Framework

Candidates evaluated on your tasks, data, latency, and cost targets.

Open-weight strategy icon

Open-weight strategy

Where open-weight models give equivalent quality with ownership, portability and a fixed cost base.

Small language models icon

Small language models

Compact models for classification, extraction and routing — the high-volume work that quietly dominates inference bills.

Routing layer icon

Routing layer

Task complexity and sensitivity decide the model, with fallbacks and cost ceilings enforced at the router.

Portability by design icon

Portability by design

An abstraction that makes swapping a model a configuration change rather than a rewrite.

Private model hosting icon

Private model hosting

Serving inside your perimeter where the data boundary requires it.

How it works

Technology Wheel in Implementation Cycle

Our LLM and SLM engineering layer is where model choice gets operationalized through evaluation and deployments that serve every need of what enterprise AI is aimed at.

  • Llama, Falcon and comparable open-weight families
  • Sarvam and Indic-capable models
  • Quantisation toolchains
  • Inference servers
  • Model gateways

Practical Approach

Industries We Tailor LLMs and SLMs

Government

Open-weight models served in-country, with no dependency on a foreign inference endpoint.

Retail & CPG

A small model handles catalogue enrichment volume; a frontier model handles the exceptions.

Technology

Routing by complexity keeps quality on hard tasks without paying frontier rates on easy ones.

Outcomes

What We Measure

Blended with intelligence, in every LLM and SLM engineering engagement, we ensure that the following outcomes are fulfilled.

  • Blended cost per thousand requests
  • Quality parity on held-out tasks
  • P95 latency
  • Vendor concentration reduction

Questions

Custom LLM & SLM Engineering, Answered Directly

Are open-weight models good enough for enterprise work?

For the majority of enterprise tasks — extraction, classification, summarisation, retrieval-grounded answering and routine tool use — yes. Reserve frontier models for genuinely hard reasoning, and prove the boundary with evaluation rather than assumption.

What is a model router?

A service that inspects each request's task type, sensitivity and complexity, then dispatches it to the appropriate model under cost and residency policy — with fallback if the primary is unavailable. It is the single highest-leverage component for AI unit economics.
