WORKSHOPS

At the Yay-Yay Conf, we offer two types of workshops: Canela and Crema workshops.

Crema workshops are paid workshops for ticket holders as well as for the general public. You can check the fee for each workshop below.

Canela workshops are free for Early Camarón and Bokeron ticket holders. For Standard Tuna tickets are available with a 50% discount. For Last Callamar tickets are available with a 30% discount. In all cases previous registration is MANDATORY. Conference ticket holders can register on our webpage with a special promo code, which is sent together with the ticket order confirmation. Check out the following video tutorial. For those who are not conference ticket holders, admission is at a fee of €50.

IMPORTANT:
  • Previous registration is mandatory due to the limited capacity of each workshop.
  • Please consider that the order confirmation including the promo codes for workshops is sent to the ticket buyer ONLY: if your company or someone else has purchased a ticket for you, make sure the buyer shares the code and all the necessary information with you.
  • Only register for those workshop you want to attend. If you are not interested in a workshop or you prefer to attend another activity, please leave your spot to someone who would like to attend.
  • Do not register to workshops happening at the same time (we do check it!).
  • Bring your laptop with you and check the basic knowledge and requirements for each workshop before registering.

Small Models, Big Agents: Fine-Tuning and Serving SLMs on Kubernetes

Building AI agents? Not every step needs a giant model. It's about right-sizing: run an agent's frequent, narrow decisions (routing, tool use, self-correction) on Small Language Models on CPUs, and reach for larger models where the task genuinely calls for them. On Kubernetes, with llama.cpp, KEDA, and Karpenter.
