New Model (GPT-5.2), Incident Integration, and Improved Document Search
April 22nd, 2026 | by Melisa Berisha
- New Language Model:
- Ritchy now uses GPT-5.2 by OpenAI as its underlying language model. Compared to the previous GPT-4.1 model, it provides improved reasoning capabilities and a deeper understanding of language.
- Automatic Integration of Incident Reports:
- Ritchy can now automatically detect whether a user request relates to a current incident or maintenance activity of the IT Center. If a match is found, the corresponding incident report is directly incorporated into the response, including status information and a link to the incident page. Incidents are prioritized by severity (incident > partial incident > maintenance > warning > notice).
- Improved Document Search:
- The way Ritchy accesses the IT Center documentation has been fundamentally redesigned. The search now uses a three-stage approach (keyword search, vector search, and semantic re-ranking) to retrieve more relevant articles. In addition, more document context is included in responses, resulting in more precise and complete answers.
- More Reliable Language Detection:
- Automatic language detection has been made more robust. In particular, for queries containing English technical terms (e.g., product names like Cisco AnyConnect), the system now more reliably identifies the user’s actual language and consistently formulates the response in that language.
- Structural Improvements:
- The internal architecture of the application has been modularized to simplify future extensions and maintenance. These changes do not result in any visible differences for end users.
