AI Researcher & LLM Evaluation – Conventional Paradigm Test (CPT) at Private

Conventional Paradigm Test (CPT) – AI Evaluation & LLM Research

Development of an experimental evaluation approach to examine “paradigmatic closure” in Large Language Models — that is, the question of how far LLMs can recognize the basic assumptions, values, and limits of the paradigms within which they generate answers.

Design and testing of an additional approach to classic AI benchmarks that does not primarily measure factual correctness or task performance, but instead examines a model’s ability to recognize alternative perspectives, make implicit assumptions visible, and reflect on the limits of its own answer or interpretation framework.

Focus areas: development of evaluation criteria and test questions · LLM evaluation and comparative model analysis · prompt and response analysis · qualitative classification of model answers · study of epistemic compression and value leakage · benchmark and literature research · development of structured assessment and analysis methods

As part of CPT, existing AI evaluation approaches and benchmarks were analyzed, and a minimalist test protocol was developed that classifies model answers by response patterns such as DIRECT, CLARIFY, PLURALIST, REFUSE, and META-AWARE. TruthfulQA was used as the basis for experimental application and comparison with existing reference answers.

About the technology

What it is

Large language models, or LLMs, are systems that generate and transform text. They power chat assistants, search assistants, drafting tools, and internal knowledge workflows. Companies bring in specialists when they need usable output, not just model access.

Common work

  • Prompt design and prompt testing for business tasks
  • Retrieval-augmented generation with company documents
  • Chat workflows for support, sales, and operations
  • Output checks for accuracy, tone, and policy fit
  • Integration into products, portals, and internal tools

Tooling stack

Strong LLM specialists work across model APIs, vector databases, orchestration layers, and evaluation tools. They know how to connect GPT-style models, open-source LLMs, and knowledge sources without creating brittle flows. They also handle logging, guardrails, and fallback paths.

When to bring help

Bring in freelance expertise when a proof of concept needs to become a reliable system. That is common in Dortmund for industrial firms, software teams, and service companies that want document search, assistant features, or multilingual support. The right specialist helps turn experiments into something teams can run every day.

What good looks like

Good professionals do more than write prompts. They test failure cases, reduce hallucinations, manage context limits, and shape prompts and retrieval so answers stay grounded. They also document the system so product, legal, and operations teams can work with it.

Delivery scope

Typical deliverables include:

  • A working assistant tied to real business data
  • A prompt and evaluation set for repeatable quality
  • A secure setup for internal or customer-facing use
  • Guidance for handover, monitoring, and future changes

Frequently asked questions

Key details about Large Language Model, drawn from the questions we get asked most.

A strong Large Language Model specialist builds systems that turn model output into something useful for a business. That can mean prompt design, retrieval over company content, answer checks, and integration into existing tools.

LLM is the broad term for large language models. GPT is one well-known family of models, but many projects use other model providers or open-source options. A good specialist should choose the model based on the task, not the brand name.

Bring in Large Language Model expertise when a prototype needs to become dependable, secure, and maintainable. That is often the point where prompt quality, grounding, guardrails, and evaluation become more important than the first demo.

The best LLM professionals usually also understand retrieval, APIs, data pipelines, and basic product thinking. For many projects, knowledge of vector search, authentication, logging, and content review is just as important as model prompts.

A simple proof of concept can start with one focused large language model specialist. A production system usually needs someone who has handled evaluation, security, and maintenance, especially if it uses internal knowledge or customer-facing text.

Large Language Model systems are better when the task involves flexible language, summarising, or answering messy questions. Rule-based automation is better for fixed decisions, and classic search is better when users need source documents rather than generated answers.

Yes. Many LLM tasks can be done remotely because the work happens in notebooks, cloud tools, and shared review cycles. On-site time only becomes important when teams need close access to sensitive data, workshop sessions, or fast stakeholder alignment in Dortmund.

Look for clear evaluation habits, not just fluent demos. A reliable Large Language Model specialist shows how they test prompts, track bad answers, handle edge cases, and explain trade-offs between model choice, cost, and quality.
