### Data
For training data details, please see the [German-RAG-CPT-Dataset](https://huggingface.co/datasets/avemio/German-RAG-CPT-HESSIAN-AI) documentation.

#### Description
CPT – Continued Pre-Training
Our CPT (Continued Pre-Training) approach is designed to enhance language models' ability to perform specific tasks through structured instruction-based learning. Drawing inspiration from "Instruction Pre-Training: Language Models are Supervised Multitask Learners," our methodology focuses on priming base models with semi-structured examples to improve their performance across three key tasks. Our training dataset comprises approximately 420,000 German language samples and 200,000 English examples, with the deliberate emphasis on German content aimed at expanding the model's German language vocabulary and capabilities.
Context-Based Question Answering
This task trains models to generate accurate responses by considering both the question and its accompanying context. For example, when analyzing cancer counseling center benefits, the model learns to extract and synthesize relevant information from provided context to formulate comprehensive answers. The training examples follow a clear structure: Question > Context > Context-based Answer.
Structured Reasoning
The reasoning task develops the model's ability to break down complex problems and arrive at solutions through systematic thinking. Training examples present problems with clear subheadings (Task, Approach, Solution) to encourage structured analysis. As shown in the music festival scheduling example, this format helps the model learn to consider multiple constraints and develop logical solutions step by step.
Intelligent Summarization
The summarization task teaches models to distill complex information into clear, organized summaries while preserving key details. Training examples demonstrate how to transform detailed explanations into well-structured bullet points or concise summaries.

It's important to note that the actual power consumption may vary depending on the specific workload and operational conditions. For accurate power consumption measurements, using dedicated power monitoring tools is recommended.

| Model          | GPU Type            | Power Consumption From GPUs | 
|----------------|---------------------|-----------------------------|
| German-RAG-MISTRAL-NEMO-CPT   | A100 ([Hessian AI supercomputer](https://hessian.ai/de/)) | 0.0144 MWh                    |

## Bias, Risks, and Limitations

Like any base language model or fine-tuned model without safety filtering, it is relatively easy for a user to prompt these models to generate harmful and generally sensitive content.
Such content can also be produced unintentionally, especially in the case of bias, so we recommend users consider the risks of applications of this technology.

Otherwise, many facts from German-RAG-MISTRAL-NEMO-CPT or any LLM will often not be true, so they should be checked.
