Applied AI engineering · Yerevan, Armenia

We don't wrap models.
We re-engineer them.

Linked LLC builds complex AI systems from the inside out. We open up large language models — weights, layers, attention, inference runtime — and reshape them for your product, your data and your hardware.

01 — Capabilities

Engineering below the API line.

Anyone can call an endpoint. We work on the model itself — so it is faster, cheaper, more accurate and fully yours.

Model surgery & fine-tuning

Full and parameter-efficient fine-tuning (LoRA, QLoRA, adapters), preference optimization and domain adaptation on your proprietary data.

SFT · DPO · RL

Quantization & distillation

Shrink frontier-class behaviour into small, efficient models. 8/4-bit and mixed-precision quantization, pruning and teacher→student distillation.

INT4 · FP8 · Pruning

Inference engineering

Custom kernels, KV-cache strategies, speculative decoding and batching. We profile every millisecond between prompt and token.

Latency · Throughput · Cost

On-device AI

Private, offline-capable models running directly on iOS and Android hardware — Neural Engine, GPU and NPU aware.

Core ML · MLX · LiteRT

Agentic systems

Multi-step agents with tool use, retrieval and memory — built with guardrails, observability and deterministic fallbacks for production.

Tools · RAG · Memory

Evaluation & interpretability

Custom benchmarks for your task, regression suites, and probing of internal activations to understand why a model behaves the way it does.

Evals · Probing · Safety

The usual approach

  • Prompt wrapper around a third-party API
  • Pay per token, forever
  • Your data leaves your infrastructure
  • One generic model for every task
  • Black box — no idea why it fails

The Linked approach

  • A model shaped specifically for your task
  • Optimized to run on hardware you control
  • Private by design — on-prem or on-device
  • Small, specialized models that beat big generic ones on your workload
  • Measured, evaluated and explainable

02 — Approach

From profile to production.

A rigorous, measurable process. Every change to a model is justified by numbers on your own evaluation set.

  1. 01

    Profile

    We define success metrics, build an evaluation set from real usage and benchmark candidate models against it.

  2. 02

    Dissect

    We look inside: which layers, heads and experts matter for your task, where compute is wasted, where errors originate.

  3. 03

    Optimize

    Fine-tune, distill, quantize and prune — iterating until quality, latency and cost targets are met together.

  4. 04

    Ship & monitor

    Deployment to cloud, edge or mobile with continuous evaluation, drift detection and a path for ongoing improvement.

03 — Frontier

Built for what comes next.

AI moves monthly. We track the research and bring what is ready into production — before it becomes a commodity.

Reasoning

Test-time compute

Models that think longer on hard problems — tuned so they only spend compute where it pays off.

Architecture

Mixture-of-Experts

Sparse models with expert routing tailored to your domain for large-model quality at small-model cost.

Edge

Small language models

Compact, specialized models that live on phones, laptops and embedded devices — fully offline.

Perception

Multimodal

Unified understanding of text, images, audio and documents in a single pipeline.

Memory

Long context & memory

Efficient attention and retrieval so systems remember what matters across millions of tokens.

Autonomy

Agents that act

Reliable agents that operate software, call APIs and complete real workflows end-to-end.

04 — Products

We ship our own AI, too.

Beyond client work, Linked LLC designs, develops and publishes its own AI-powered applications for iOS and Android — putting the same on-device and optimization research directly into people's hands.
