Last position:
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
A Large Language Model, or LLM, is a machine learning system trained on extensive text data to understand and generate natural language. It can draft content, answer questions, summarize documents, classify text and support conversations. Modern LLM solutions may also process code, images or structured business data when connected to suitable models and tools.
What it builds
Companies use LLMs as part of customer support assistants, internal knowledge search, document workflows and content operations. They can also power meeting summaries, contract analysis, software assistance and natural-language interfaces for business systems.
- Retrieval-augmented generation with company documents
- Prompt and response workflows for business processes
- Evaluation pipelines for accuracy, safety and consistency
- APIs that connect models with existing applications
Ecosystem and tooling
The ecosystem includes foundation models such as GPT, Claude and Llama, along with APIs, open-source model runtimes and embedding services. Practical solutions often use vector databases, orchestration frameworks such as LangChain or LlamaIndex, structured output, function calling and observability tools. Strong expertise also covers data preparation, model selection and cloud deployment.
When expertise matters
Freelance specialists are valuable when a proof of concept must become a dependable product, or when an existing chatbot produces unreliable answers. They help companies define useful tasks, select an appropriate model and control data access, latency and operating costs.
- A prototype needs production-ready architecture
- Answers must cite trusted internal sources
- Sensitive information requires clear safeguards
- Teams need repeatable testing and monitoring
Working in Essen
In Essen and the wider Ruhr region, LLM projects can support industrial operations, logistics, energy, healthcare and professional services. Experts may work remotely, on site or in a blended setup, depending on data access and collaboration needs. German-language quality, domain vocabulary and integration with local business processes can be important project requirements.
What strong experts deliver
The best professionals connect language-model capability with a clear business outcome. They test prompts and retrieval, measure factuality and refusal behavior, protect confidential data and document decisions. They also know when a simpler search, rules-based workflow or conventional software component is more reliable than an LLM.
Frequently asked questions
Questions about Large Language Model? Start with the answers below.
A Large Language Model can support document search, customer conversations, summarization, classification, content generation and natural-language access to business systems. The best use case has clear source data, defined users and a way to evaluate whether the output is useful.
An LLM handles flexible language and can generate responses, while traditional search is often more predictable for locating exact information and rules-based software is easier to control for fixed decisions. Many reliable solutions combine these approaches instead of replacing one with another.
A strong Large Language Model specialist usually understands APIs, Python, data pipelines, vector databases, retrieval-augmented generation and cloud services. Experience with security, evaluation, prompt design and application integration is equally important for production work.
The required depth depends on the project, not just its label. A simple prototype may need focused model and API knowledge, while a production LLM application requires expertise in data quality, evaluation, access control, monitoring and failure handling.
Yes, much Large Language Model work can be completed remotely through shared repositories, cloud environments and structured workshops. On-site collaboration in Essen can still help when specialists must access restricted systems, understand operational processes or work closely with domain teams.
A Large Language Model choice should follow the task, language needs, context limits, integration options, data policy and deployment model. GPT, Claude and Llama each fit different requirements, so specialists should compare them with representative company data rather than relying on brand preference.
A capable LLM professional defines test cases before implementation and measures factuality, relevance, safety, latency and consistency. They should also show how the system handles missing information, adversarial input, sensitive data and changes in the underlying documents.
Before starting, a Large Language Model freelancer should clarify the target users, source data, model access, deployment environment, success criteria and ownership of prompts and evaluation sets. They should also establish whether the work involves fine-tuning, retrieval, workflow automation or a broader application.
