Open Source AI Day — Berlin

Berlin's Open Source AI Day brings together the maintainers, researchers, and engineers building and shipping with open-weight models. Single-day, single-track, ticket cost covers room and lunch only. The day's themes: open-weight model selection (Llama, Mistral, Qwen, Gemma), fine-tuning techniques that don't require a research lab, local inference stacks (vLLM, llama.cpp, MLX), and the licensing landscape teams need to navigate before shipping. Talks are 20 minutes. Lightning rounds in the afternoon. Stuhl-Karaoke after dinner (you've been warned).
