Man benötigt dazu eine Suchmaschine für diese speziellen Daten und ein Chat-System, das die Suche in dieser Suchmaschine durchführt.\n\nHier bietet es sich an, in YaCy einen KI-Chat einzubauen, damit der YaCy-Suchindex für den Chat genutzt werden kann. Genau das haben wir gemacht und zeigen:\n- wie man in YaCy einen geeigneten Suchindex aufbaut,\n- wie man ein lokales LLM Inference System installiert (mit Ollama),\n- wie man YaCy so konfiguriert, dass es das LLM verwendet,\n- wie das Chat System in YaCy aussieht.\n\nDas ist genau die Lösung für das, was ansonsten bei Cloud-Diensten als »GPT« oder »Agent« angeboten wird. Hier ist es aber ein KI/RAG-System, das auf dem eigenen Rechner läuft und damit auch im Intranet oder für private Daten geeignet ist.\n\nLicensed to the public under http://creativecommons.org/licenses/by/4.0","original_language":"deu","persons":["Michael Christen"],"tags":["53","2026","clt26","Vortrag","V7","clt26-deu","Day 2"],"view_count":192,"promoted":false,"date":"2026-03-29T13:00:00.000+02:00","release_date":"2026-03-29T00:00:00.000+01:00","updated_at":"2026-04-18T13:00:05.139+02:00","length":1440,"duration":1440,"thumb_url":"https://static.media.ccc.de/media/events/clt/2026/53-b391fb6d-5b6e-5758-bbe7-d0ee5d2c2046.jpg","poster_url":"https://static.media.ccc.de/media/events/clt/2026/53-b391fb6d-5b6e-5758-bbe7-d0ee5d2c2046_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/clt/2026/53-b391fb6d-5b6e-5758-bbe7-d0ee5d2c2046.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/clt/2026/53-b391fb6d-5b6e-5758-bbe7-d0ee5d2c2046.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/clt26-322-ki-chat-mit-eigener-suchmaschine-rag-in-yacy","url":"https://media.ccc.de/public/events/b391fb6d-5b6e-5758-bbe7-d0ee5d2c2046","conference_title":"Chemnitzer Linux-Tage 2026","conference_url":"https://media.ccc.de/public/conferences/clt26","related":[],"recordings":[{"size":113,"length":1440,"mime_type":"video/webm","language":"deu","filename":"clt26-53-deu-KI-Chat_mit_eigener_Suchmaschine_RAG_in_YaCy_webm-hd.webm","state":"new","folder":"webm-hd","high_quality":true,"width":1920,"height":1080,"updated_at":"2026-03-30T00:25:36.507+02:00","recording_url":"https://cdn.media.ccc.de/events/clt/2026/webm-hd/clt26-53-deu-KI-Chat_mit_eigener_Suchmaschine_RAG_in_YaCy_webm-hd.webm","url":"https://media.ccc.de/public/recordings/98048","event_url":"https://media.ccc.de/public/events/b391fb6d-5b6e-5758-bbe7-d0ee5d2c2046","conference_url":"https://media.ccc.de/public/conferences/clt26"},{"size":44,"length":1440,"mime_type":"video/webm","language":"deu","filename":"clt26-53-deu-KI-Chat_mit_eigener_Suchmaschine_RAG_in_YaCy_webm-sd.webm","state":"new","folder":"webm-sd","high_quality":false,"width":720,"height":576,"updated_at":"2026-03-29T22:08:26.884+02:00","recording_url":"https://cdn.media.ccc.de/events/clt/2026/webm-sd/clt26-53-deu-KI-Chat_mit_eigener_Suchmaschine_RAG_in_YaCy_webm-sd.webm","url":"https://media.ccc.de/public/recordings/98007","event_url":"https://media.ccc.de/public/events/b391fb6d-5b6e-5758-bbe7-d0ee5d2c2046","conference_url":"https://media.ccc.de/public/conferences/clt26"},{"size":21,"length":1440,"mime_type":"audio/mpeg","language":"deu","filename":"clt26-53-deu-KI-Chat_mit_eigener_Suchmaschine_RAG_in_YaCy_mp3.mp3","state":"new","folder":"mp3","high_quality":false,"width":0,"height":0,"updated_at":"2026-03-29T16:27:02.514+02:00","recording_url":"https://cdn.media.ccc.de/events/clt/2026/mp3/clt26-53-deu-KI-Chat_mit_eigener_Suchmaschine_RAG_in_YaCy_mp3.mp3","url":"https://media.ccc.de/public/recordings/97824","event_url":"https://media.ccc.de/public/events/b391fb6d-5b6e-5758-bbe7-d0ee5d2c2046","conference_url":"https://media.ccc.de/public/conferences/clt26"},{"size":12,"length":1440,"mime_type":"audio/opus","language":"deu","filename":"clt26-53-deu-KI-Chat_mit_eigener_Suchmaschine_RAG_in_YaCy_opus.opus","state":"new","folder":"opus","high_quality":false,"width":0,"height":0,"updated_at":"2026-03-29T16:26:58.755+02:00","recording_url":"https://cdn.media.ccc.de/events/clt/2026/opus/clt26-53-deu-KI-Chat_mit_eigener_Suchmaschine_RAG_in_YaCy_opus.opus","url":"https://media.ccc.de/public/recordings/97823","event_url":"https://media.ccc.de/public/events/b391fb6d-5b6e-5758-bbe7-d0ee5d2c2046","conference_url":"https://media.ccc.de/public/conferences/clt26"},{"size":39,"length":1440,"mime_type":"video/mp4","language":"deu","filename":"clt26-53-deu-KI-Chat_mit_eigener_Suchmaschine_RAG_in_YaCy_sd.mp4","state":"new","folder":"h264-sd","high_quality":false,"width":720,"height":576,"updated_at":"2026-03-29T16:15:48.186+02:00","recording_url":"https://cdn.media.ccc.de/events/clt/2026/h264-sd/clt26-53-deu-KI-Chat_mit_eigener_Suchmaschine_RAG_in_YaCy_sd.mp4","url":"https://media.ccc.de/public/recordings/97796","event_url":"https://media.ccc.de/public/events/b391fb6d-5b6e-5758-bbe7-d0ee5d2c2046","conference_url":"https://media.ccc.de/public/conferences/clt26"},{"size":93,"length":1440,"mime_type":"video/mp4","language":"deu","filename":"clt26-53-deu-KI-Chat_mit_eigener_Suchmaschine_RAG_in_YaCy_hd.mp4","state":"new","folder":"h264-hd","high_quality":true,"width":1920,"height":1080,"updated_at":"2026-03-29T16:07:22.116+02:00","recording_url":"https://cdn.media.ccc.de/events/clt/2026/h264-hd/clt26-53-deu-KI-Chat_mit_eigener_Suchmaschine_RAG_in_YaCy_hd.mp4","url":"https://media.ccc.de/public/recordings/97790","event_url":"https://media.ccc.de/public/events/b391fb6d-5b6e-5758-bbe7-d0ee5d2c2046","conference_url":"https://media.ccc.de/public/conferences/clt26"}]}
