In this episode of the Ruby AI Podcast, hosts Valentino Stoll and Joe Leo
welcome AI and Ruby expert Chris Hasinski. They delve into the benefits and
challenges of self-hosting AI models, including control over model updates, cost
considerations, and the ability to fine-tune models. Chris shares his journey
from machine learning at UC Davis to his extensive work in AI and Ruby, touching
upon his contributions to open source projects and the Ruby AI community. The
discussion also covers the limitations of current LLMs (Large Language Models)
in generating Ruby code, the importance of high-quality data for effective AI,
and the potential for Ruby to become a strong contender in AI development.
Whether you're a Ruby enthusiast or interested in the intersection of AI and
software development, this episode offers valuable insights and practical
advice.
