Featured event

How to train your own LLM 🧑💻 & networking 🤝
Most LLMs live in huge data centers. However, recent advances now allow models to be personalized and deployed on any computer with no internet connection.
How do you teach a model new knowledge and how do you make it smaller? Join Ovi as he walks through the whole journey of building your own personalised lightweight AI model, step by step.
This session is for everyone — developers and anyone curious about AI.
🎤 Presentation
- Overview:
We’ll start with an off-the-shelf AI model.
From there, we’ll explore how fine-tuning teaches them new information and how compression allows them to run anywhere.
We’ll finish with a live demo of a model that can answer questions about our custom information.
Whether you're a developer or simply curious about AI, you’ll leave with a clear understanding of how AI models learn and common techniques for compressing them. - Format:
Presentation + Live Demo + Q&A - Duration:
About 30 - 40 minutes (the rest of the time will be a networking part) - Note:
No equipment needed: speaker will handle all setup
