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 does

Prompt Engineering shapes the instructions, context and examples given to large language models so they produce useful, consistent results. It supports chat assistants, document analysis, content workflows, structured extraction, classification and AI features inside existing products. The work combines clear language with technical control over model behaviour.

Core methods

Professionals turn vague business goals into testable prompt patterns. They select suitable instructions, roles, examples, output schemas and guardrails, then refine them against representative inputs. Retrieval-augmented generation, tool calling, structured outputs and multi-step chains often form part of the solution. Good prompts are designed for maintainability, not just a successful demonstration.

Tools and ecosystem

The ecosystem includes OpenAI models, Anthropic Claude, Google Gemini, open-weight models and orchestration tools such as LangChain and LlamaIndex. Specialists may work with vector databases, embedding models, evaluation frameworks, Python, APIs and observability tools. They also understand token limits, model context, temperature, latency, privacy and version changes.

Typical projects

  • Create an internal assistant that answers from approved company documents
  • Extract fields from contracts, invoices or support messages into structured data
  • Build prompt flows for classification, summarisation and content review
  • Connect language models to search, business tools or controlled actions
  • Establish evaluation sets and regression checks for production releases

When to hire expertise

Companies usually bring in freelance specialists when an AI proof of concept gives uneven answers, needs stronger safeguards or must move into production. Support is also valuable when teams need a model comparison, a reusable prompt library or a clear evaluation process. In Dortmund, hybrid collaboration can suit organisations that combine local operations with remote product and data teams. English is common in model documentation and technical work; German may matter for user-facing prompts and regulated business content.

What quality looks like

Strong professionals connect prompts to measurable business outcomes rather than relying on clever wording alone. They ask about source data, failure cases, permissions, escalation paths and acceptable uncertainty. They document assumptions, test adversarial inputs and separate prompt changes from model changes. They can explain trade-offs to product, legal, security and domain teams, while leaving behind prompts and evaluation assets others can maintain.

Frequently asked questions

Quick answers to the questions that come up most around Prompt Engineering.

Prompt Engineering is used to guide language models toward useful, accurate and consistent outputs. Typical applications include assistants, document processing, retrieval-based question answering, classification, summarisation and controlled tool use.

Prompt Engineering changes the instructions, context and examples supplied to a model without retraining its internal weights. Fine-tuning changes model behaviour through additional training data, while retrieval adds external knowledge at request time; a specialist can assess which approach fits the task.

A strong Prompt Engineering specialist often combines language-model APIs with Python, evaluation design, retrieval-augmented generation, vector search and structured data handling. Knowledge of product design, data protection, security and the relevant business domain is also valuable.

The right level of Prompt Engineering experience depends on the risk and complexity of the use case. A simple internal workflow may need focused prompt design, while a customer-facing or regulated system calls for production testing, monitoring, fallback logic and documented governance.

Prompt Engineering is well suited to remote collaboration because prompts, test cases and model outputs can be reviewed online. On-site sessions in Dortmund can still help when specialists need direct access to domain experts, sensitive processes or teams shaping the user experience.

Look for a Prompt Engineering professional who shows a repeatable evaluation method, not only impressive sample outputs. Ask how they handle ambiguous requests, unsupported claims, sensitive data, prompt injection, model changes and cases where the system should decline.

Prompt Engineering does not replace software engineering, data work or subject-matter knowledge. Reliable AI features still need sound APIs, access controls, source data, testing and human review, with prompts working as one part of the wider system.

Experienced Prompt Engineering professionals may work across OpenAI, Anthropic Claude, Google Gemini and open-weight models. They compare instruction formats, context handling, tool interfaces and output reliability rather than assuming that one model fits every workflow.

The average hourly rate of freelancers in Dortmund, Germany who have used Prompt Engineering in their recent projects is 98 €, which corresponds to a daily rate of about 783 € based on an 8-hour working day.
