I'd recommend this course for anyone working on operational systems where LLM output may play a load-bearing role, even if you're not of the engineering persuasion, but are up for getting your hands dirty with some code.

The course validated my intuitions that these foundations apply just as much to generative AI applications and has given me a road-tested pragmatic framework for applying them to the weird world of LLMs and AI engineering.

Their approach thoroughly resonates with my experience as a data scientist: look at your data, perform thorough error analysis, develop metrics that matter, and iterate via experimentation and user-feedback.

I recently completed @hamel.bsky.social and @sh-reya.bsky.social's AI Evals For Engineers & PMs, which presented practical frameworks for identifying appropriate dimensions of quality, creating automatic validators to measure at scale, and effective feedback loops that enable continual improvement
