Conf42 Large Language Models (LLMs) 2026

First things first, please watch the CFP tips and tricks video - 5 minutes. It will increase your chances of having your talk accepted.

Let’s talk about what’s really happening with large language models.

If you spend your days fine-tuning models, building chatbots, working with embeddings, or trying to make LLMs useful (and reliable) in production, this event’s for you.

We’ll dig into what’s working (and what’s not) in the world of LLMs:

• Fine-tuning, prompt engineering, and retrieval-augmented generation
• Building real-world applications powered by LLMs
• Managing cost, latency, and scalability for inference
• Evaluating model performance and dealing with hallucinations
• Open-source models, frameworks, and deployment strategies
• Privacy, security, and responsible AI practices
• Lessons learned from integrating LLMs into existing systems

Come hang out with people who build, break, and experiment with language models every day. Share what you’ve learned and pick up a few ideas to make your next model more capable and reliable.

Hope to see you there,
