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
Prompt Engineering is the structured design, testing and refinement of instructions for generative AI systems. It helps language models produce useful, consistent and controlled results for text, images, code and data tasks. Common terms include prompt design, LLM prompting and generative AI prompting.
What it builds
Professionals use prompts to shape customer support assistants, content workflows, research tools, document extraction and internal knowledge interfaces. They define roles, context, examples, constraints and output formats so an AI system can support a clear business process rather than produce generic responses.
- Conversational assistants with defined behavior
- Structured extraction from documents and emails
- Classification, summarization and review workflows
- Prompt libraries for recurring business tasks
Ecosystem and tooling
The work can involve GPT models, Claude, Gemini and open-weight language models, along with retrieval-augmented generation, embeddings and vector databases. Strong specialists also use evaluation datasets, experiment tracking, model APIs, guardrails and observability tools. They understand how prompts fit into Python or JavaScript services and automation platforms.
When companies need it
Companies bring in freelance expertise when prototypes produce uneven results, model behavior changes between releases or teams cannot agree on a dependable evaluation method. Essen-based businesses may prefer on-site workshops for process discovery, while distributed teams often collaborate remotely through shared prompt repositories, test suites and product documentation.
- AI pilots need a repeatable prompt strategy
- Existing workflows require better output control
- Teams need evaluation criteria and test cases
- Sensitive information needs careful prompt handling
What strong professionals deliver
A strong professional connects prompt choices to measurable business outcomes without treating prompting as trial and error. They document assumptions, create representative test cases, compare model behavior and design fallbacks for unclear or unsafe requests. They also communicate clearly with product, domain and language teams, including German-speaking stakeholders when the use case requires it.
Selecting the right specialist
Ask for examples of prompt systems, evaluation methods and production handover materials, not only isolated impressive outputs. Relevant experience may include retrieval, tool calling, structured JSON responses, content safety, privacy-aware data handling or multilingual workflows. The right specialist explains trade-offs between prompt changes, model selection, fine-tuning and workflow design, then leaves a process your team can maintain.
Frequently asked questions
Curious about Prompt Engineering? Here are the answers that come up again and again.
Prompt Engineering is used to guide generative AI systems toward relevant, consistent and correctly formatted results. Companies apply it to assistants, document processing, research, content operations, classification and automation workflows.
Prompt Engineering changes the instructions and context given to a model, while fine-tuning changes the model through additional training data. Prompting is often easier to revise, whereas fine-tuning may be useful when a stable style or specialized behavior cannot be achieved through instructions alone.
A strong Prompt Engineering specialist may also understand retrieval-augmented generation, embeddings, vector databases, model APIs and evaluation design. Experience with Python or JavaScript, workflow automation, structured outputs and privacy-aware data handling is valuable for production work.
The required depth depends on the task. A simple prompt library may need focused workflow knowledge, while a production assistant requires experience with evaluation, retrieval, tool calling, failure handling and model changes. Ask candidates to explain how they tested and maintained their prompt systems.
Prompt Engineering is well suited to remote collaboration when teams can share requirements, test data, prompt versions and evaluation results. On-site sessions in Essen can still help with domain discovery, stakeholder workshops and alignment on sensitive business processes.
Quality is shown through repeatable evaluation rather than a few attractive examples. A capable Prompt Engineering professional defines success criteria, tests realistic edge cases, measures consistency and documents when a model should defer, ask for clarification or trigger a fallback.
Prompt Engineering benefits from familiarity with model behavior, API limits and instruction formats across providers such as OpenAI, Anthropic and Google. Vendor knowledge helps, but a strong specialist can transfer principles between models and explain the trade-offs involved.
Hire a Prompt Engineering freelancer when an AI prototype needs dependable outputs, a team lacks evaluation practice or an existing workflow is difficult to maintain. A specialist can establish a prompt strategy, test process and handover framework without requiring a permanent internal role.
