Technical articles and tutorials
Even with temperature=0, LLMs can produce different outputs due to batch composition changes. Learn how batch-invariant kernels solve this production challenge.
Understanding why context engineering is crucial for LLM agents - giving models only what they really need for better performance and lower costs.
Learn how to fine-tune Hugging Face embedding models on your own data using contrastive learning with MultiNegativeRankingLoss.
Understanding the massive memory demands of finetuning 70B parameter models and efficient solutions like LoRA and QLoRA.
This project aims to demystify the inner workings of modern Large Language Models (LLMs) by implementing Llama2 from scratch.
Arbeitsprozesse der Bundesverwaltung digitalisieren: dafür steht das seit fünf Jahren jährlich ausgelobte Tech4GermanyFellowship. Es verbindet die zwei Welten „Bürokratie“ und „Tech“. HM-Bachelorand Christian Bernhard war 2022 als Stipendiat dabei.
