LLM Development

LLM application engineering: retrieval-augmented systems, fine-tuning, prompt and tool architecture, and the evaluation that measures them against requirements.

About LLM Development

LLM development is the engineering discipline of building reliable applications on a large language model. It encompasses retrieval-augmented generation over proprietary documents and data, and fine-tuning where a general model does not meet the requirement. It also covers the design of prompts and tool interfaces as versioned software, and evaluation methods that measure correctness. The objective is a system whose behavior we can specify, measure and reproduce.

We treat retrieval quality, prompt structure and tool definitions as engineering artifacts subject to review, versioning and regression testing. We measure retrieval relevance and citation accuracy against thresholds agreed in the architecture review, and a result below threshold halts the release. We build the application so you can change model provider without a rewrite, which limits exposure to a provider's pricing, availability or policy changes.

What you receive

  • Retrieval pipeline with measured relevance and citation
  • Versioned prompt and tool-interface definitions
  • Fine-tuned models where justified by evaluation
  • Regression gate in the release pipeline

When to engage

Engage when an LLM application must meet a stated accuracy standard, produce reproducible results and remain operable through a change of model provider.

  • AI Product Development

    End-to-end delivery of an AI-enabled product, with a single supplier accountable for its release.

  • Agentic AI Systems

    Autonomous and supervised agents that plan and execute actions across tools and systems.

  • Generative AI

    Text, image, audio and code generation features, released with evidence that their output meets the standard set for them.

  • Reinforcement Learning

    Learned decision policies for operational problems in which each choice changes the options available for the next.

  • Custom AI Development

    Custom models and systems for requirements that standard approaches, hosted models and packaged software do not meet.
