https://docs.ai.gwdg.de/en/user/ai-services/chat-ai/index.htmlChat AI is a web service that provides access to a wide range of large language models (LLMs) through a feature-rich, user-friendly interface. It offers a curated selection of popular open-weights models running in our own data center, alongside anonymized access to external models from commercial providers. The web interface is hosted on GWDG’s cloud infrastructure and securely forwards your requests through our scalable SAIA backend to the selected model, routing either to local HPC hardware or, for models marked as external, to the commercial vendor’s service endpoint. Our AI team updates the list of supported models regularly and is continuously developing new features.Hugoenhttps://docs.ai.gwdg.de/en/user/ai-services/chat-ai/models/index.htmlMon, 01 Jan 0001 00:00:00 +0000https://docs.ai.gwdg.de/en/user/ai-services/chat-ai/models/index.htmlChat AI provides a large assortment of state-of-the-art open-weight Large Language Models (LLMs) which are hosted on our platform with the highest standards of data protection. The data sent to these models, including the prompts and message contents, are never stored at any location on our systems. Additionally, Chat AI offers models hosted externally such as Anthropic Claude and OpenAI GPT-5. Available models are regularly upgraded as newer, more capable ones are released. We select models to include in our services based on user demand, cost, and performance across various benchmarks, such as HumanEval, MATH, HellaSwag, MMLU, etc. Certain models are more capable at specific tasks and with specific settings, which are described below to the best of our knowledge.https://docs.ai.gwdg.de/en/user/ai-services/chat-ai/faq/index.htmlMon, 01 Jan 0001 00:00:00 +0000https://docs.ai.gwdg.de/en/user/ai-services/chat-ai/faq/index.htmlData Privacy Are my conversations or usage data used for AI training or similar purposes? No, whether you use internal or external models, your conversations and data are not used to train any AI models. When using internal models, are my messages and conversations stored on your servers at any stage? No, user messages and AI responses are not stored at any stage on our servers. Once your message is sent and you receive the response, the conversation is only available in your browser.https://docs.ai.gwdg.de/en/user/ai-services/chat-ai/features/index.htmlMon, 01 Jan 0001 00:00:00 +0000https://docs.ai.gwdg.de/en/user/ai-services/chat-ai/features/index.htmlThis section collects all functionality that extends and customizes Chat AI beyond basic text generation. Features let you shape the assistant’s personality, integrate external knowledge, and configure model behavior for different use cases. The Version history is also tracked here, showing which features were added or updated in each release. Available Features Memory Memories are pieces of information that the chatbot can learn from conversation to behave in a more personalized way. Personas Define roles and tones for the assistant (e.g., interviewer, tutor, casual style). Personas make it easy to quickly switch the model’s behavior. Arcana / Retrieval-Augmented Generation (RAG) Connect your own data sources (documents, notes, datasets) to ground responses in factual context. Tools Chat AI models are given access to a variety of tools to accomplish non text-based tasks or improve responses. Web search Image Generation Image Modification Text to speech (tts) MCP Support You can add custom public Model Context Protocol (MCP) servers to Chat AI.
