When a private language-model server makes sense, which hardware it needs and what it costs.
In RAG, documents are extracted, divided into traceable sections, indexed as vectors, and retrieved according to the question. The process becomes productive only with source citation, version status, and server-side acc...
Read answerRAG is particularly suitable for variable knowledge and verifiable answers; Fine-Tuning is more appropriate for stable behavior, technical language, or a fixed output format. New facts alone are rarely a good reason for...
Read answerThree levels are measured separately: technical quality with versioned test cases, user experience with Time to First Token and end-to-end latency, and operation with token rate, queue, errors, and memory. At least p50 a...
Read answerA central identity provider authenticates users via OIDC; roles and tenant are checked server-side in each request. At least user, editorial, and administrative rights should be separated. Tenant separation must also app...
Read answerOnly what is necessary for operation, security, and proof is logged: time, pseudonymous user ID, model and prompt version, status, token counts, and correlation ID. Complete prompts and responses are excluded from the lo...
Read answerThe integration is done through a secure API gateway and small, domain-specific adapters. Reading and summarizing are separated from writing actions; changes in CRM or DMS require validation, authorization, idempotency,...
Read answerSizing is based on the data sheet of the specific server and a measurement under realistic full load – not on the average power consumption at idle. Power connection, UPS, power paths, waste heat, airflow, temperature, n...
Read answerAvailability is achieved through separate failure domains: at least 2 service instances, health checks, load balancers, replicated state data, and a tested fallback. Two processes on the same server do not protect agains...
Read answerA productive AI service requires measurable SLIs and SLOs for availability, response time, error rates, and professional quality, as well as clear responsibilities for platform, model, data, data protection, and professi...
Read answerYes, an LLM server can operate completely without internet access, provided that all necessary models, data, and software are installed locally. However, this requires careful planning and implementation to ensure that a...
Read answerThe encryption of models, prompts, and documents at rest is typically achieved through the use of symmetric or asymmetric encryption methods. Symmetric methods use a shared key, while asymmetric methods use a key pair co...
Read answerThe license terms for locally operated language models vary depending on the provider and model. These models are often available under open-source licenses or commercial licenses. Open-source models typically have less...
Read answerThe sizing of GPU memory for a model depends on several factors, including the size of the model, the batch size, and the type of data processing. First, the number of parameters in the model should be determined, as eac...
Read answerYes, a language model can fundamentally be run on CPUs, but performance and processing time are significantly limited compared to GPUs. CPUs are capable of performing the calculations required to run a language model; ho...
Read answerThe separation of development, test, and production environments in an LLM system is achieved by implementing separate environments that each utilize specific resources and configurations. Development environments are of...
Read answerProtecting an internal Retrieval-Augmented Generation (RAG) system from manipulated documents requires several measures. First, documents should be encrypted during storage and transmission to prevent unauthorized access...
Read answerTo prevent credentials from ending up in prompts or logs, sensitive information should never be written directly into the code or logs. Instead, it is advisable to use environment variables to store credentials. Addition...
Read answerDeleting personal data from vector databases and logs requires specific steps. First, the data that needs to be deleted should be identified. Then, it is important to apply the appropriate deletion methods to ensure that...
Read answerThe parallel operation of multiple language models can be beneficial when there are different requirements for language processing. For example, specialized models can be used for specific domains or tasks to increase ac...
Read answerThe selection of an embedding model for German specialized documents depends on several factors, including the specific domain, the availability of training data, and the desired accuracy. Models like BERT or its variant...
Read answerThe choice of a vector database for an internal knowledge system depends on various factors, including the type of data, scalability, and integration capabilities. Popular options include Pinecone, Weaviate, and Milvus,...
Read answerA reranker improves the quality of Retrieval-Augmented Generation (RAG) answers when it can better assess the relevance of the retrieved information than the original retrieval system. This often occurs through the appli...
Read answerThe preparation of scanned PDFs and tables for Retrieval-Augmented Generation (RAG) involves several steps. First, Optical Character Recognition (OCR) is applied to extract text from the scanned documents. Next, the extr...
Read answerTo get a private AI assistant to cite its sources, it is important to make clear requests that target the sources of the information. Many AI models are programmed to generate information without specifying sources. One...
Read answerA Retrieval-Augmented Generation (RAG) system can take access rights from document management systems (DMS) or SharePoint by accessing the permissions stored in these systems. This typically occurs via APIs or integratio...
Read answerA robust test set for an internal language model should cover a variety of test cases that examine different aspects of language processing. This includes syntactic, semantic, and pragmatic dimensions. The selection of t...
Read answerControlled attack and abuse tests against AI assistants require a structured approach. First, a test plan should be created that defines the objectives, methods, and scope of the tests. Next, appropriate test environment...
Read answerA rollback after a failed model update requires careful planning and execution. First, a backup of the previous model should be available to ensure a smooth return. The rollback procedure includes stopping the current mo...
Read answerThe choice of operating environment for an LLM server depends on various factors, including scalability, resource management, and use case. Containers provide a flexible and lightweight way to isolate and scale applicati...
Read answerUpdating models without long downtime requires careful planning and the use of appropriate techniques. A common method is Blue-Green Deployment, which uses two identical production environments. While one environment is...
Read answerTo enable secure remote access to an internal LLM server, several measures are necessary. First, a VPN connection should be established to encrypt the traffic. Additionally, authentication mechanisms such as Multi-Factor...
Read answerThe energy consumption of an AI server can be captured using monitoring tools that measure power usage in real-time. These tools often provide detailed analyses and reports that help optimize consumption. To limit energy...
