Christian shows how embedding-driven semantics can guard against hallucinations, dynamically route tasks, and supercharge Retrieval-Augmented Generation (RAG) workflows. Combined with Small or Large Language Models, embeddings offer a scalable way to build AI systems that aim to be more accurate, efficient, and context-aware. If you're ready to move beyond LLM hype, discover a semantic-centric approach in a pragmatic way. ## Speaker ### [Christian Weyer](https://www.wearedevelopers.com/@christian-weyer) Thinktecture AG, CTO ## Related talks at this congress - [Inside the Mind of an LLM](https://www.wearedevelopers.com/events/world-congress-2025/sessions/831-inside-the-mind-of) — Emanuele Fabbiani - [Self-Hosted LLMs: From Zero to Inference](https://www.wearedevelopers.com/events/world-congress-2025/sessions/625-self-hosted-llms) — Cedric Clyburn, Roberto Carratalá - [Adding knowledge to open-source LLMs](https://www.wearedevelopers.com/events/world-congress-2025/sessions/734-adding-knowledge-to) — Harshita Seth, Sergio Perez - [From Zero to Hero: How to put GPT LLMs & friends into your applications - Generative AI in Action](https://www.wearedevelopers.com/events/world-congress-2025/sessions/456-from-zero-to-hero) — Christian Weyer, Sebastian Gingter
