Scale and operate

Run AI in production with tests, releases and monitoring

We build the engineering lifecycle around machine learning models and LLM applications: reproducible training, versioned prompts, evaluation, release controls and monitoring.

In short

MLOps and LLMOps move AI systems from experiment to controlled production. Models, prompts, datasets and retrieval settings are versioned, automated quality gates run before release, rollout is staged with rollback, and drift, latency, cost and failures are monitored after launch.

01 The problem

What problem does this solve?

An AI prototype that worked on someone's laptop is hard to run again, repeat or explain. Nobody can say which data, prompt or model version produced a result, so a drop in quality is hard to trace.

Models, prompts and data keep changing, and quality can slip without anyone noticing. Without evaluation, release controls and monitoring, every change carries risk, and what each answer costs is a surprise.

02 What we build

What do we build?

  • Reproducible training and experiment pipelines
  • Versioning of datasets, models, prompts and retrieval settings
  • Automated quality and regression evaluation
  • Release gates with staged rollout and rollback
  • Model gateways and serving infrastructure
  • Monitoring of drift, quality, latency and token cost
  • Tracing and failure analysis for debugging

03 Architecture

What does a typical architecture look like?

Typical architecture of MLOps and LLMOps The flow runs from top to bottom. Experiments: Reproducible training, Dataset versioning. Registry: Model and prompt versions, Evaluation datasets. Release: Automated quality gates, Staged rollout and rollback. Serving: Model gateway, Inference infrastructure. Monitoring: Drift and quality, Latency, cost and tokens. Tracing and failure analysis throughout. EXPERIMENTS Reproducible training Dataset versioning REGISTRY Model and prompt versions Evaluation datasets RELEASE Automated quality gates Staged rollout and rollback SERVING Model gateway Inference infrastructure MONITORING Drift and quality Latency, cost and tokens Tracing and failure analysis throughout
Experiments produce versioned assets, automated gates decide what is released, and monitoring feeds quality, drift and cost back into the next change.

04 How it goes

How does the work usually go?

  1. Take stock of your AI systems

    We list the models, prompts, datasets and services in use, how each is released today, and where quality or cost is not measured.

  2. Version and reproduce

    We put training, datasets, models, prompts and retrieval configurations under version control, so any result can be reproduced and traced.

  3. Build evaluation and gates

    We assemble evaluation datasets from representative cases and add automated quality and regression checks that gate each release.

  4. Serve and roll out in stages

    We set up serving and a model gateway, with staged rollout and rollback, so a bad change can be reversed.

  5. Monitor and improve

    We monitor drift, quality, latency and cost, and review the results to decide what to change next.

The final stack follows your requirements and what you already run. How we choose technology

06 A typical situation

What does this usually look like?

A team has an AI assistant in production and wants to change a prompt or switch model provider, but has no way to tell whether the change makes answers better or worse.

We build an evaluation set from representative questions, add regression checks and a staged release with rollback, and monitor quality, latency and cost afterward.

07 Questions

Questions people ask

MLOps covers machine learning models, with training pipelines, registries, serving and drift monitoring. LLMOps covers applications built on foundation models, with prompts, retrieval, gateways, evaluation and token cost. A system can need both.

The controls should be in proportion to the risk. A small feature may need only versioned prompts, an evaluation set and basic monitoring, and we scale up from there when the stakes justify it.

We run comparisons on your own cases rather than on generic benchmarks, against the quality and speed your tasks need.
