When developing an LLM, which core components should you focus on, and how can you avoid potential pitfalls? How do you balance data quality, model architecture, and computational resources? What do you think are the most critical steps?

Struggling with data quality before training an LLM, I’d end up manually cleaning it like a stressed-out janitor, only to get a "404: Common Sense Not Found" error anyway 😅 The simplest mistake? Thinking clean data means clean code! 🧹✨
I'd say the most time-consuming part of developing an LLM is designing a conversational interface—both aim for "intelligent" interaction with users, but the processes differ significantly. In UX, we iterate quickly with rough wireframes and user tests to build a minimum viable prototype. Similarly, with LLMs, starting with a small, focused prototype (like a model that chats over private documents) and refining it through continuous feedback is key. This approach saves resources and helps spot weaknesses early.
Balancing data quality and compute resources reminds me of the "component library" strategy in design systems. First, you standardize core components (e.g., 3-4 prompt templates and a small in-context learning dataset), then scale them up. For LLMs, you start by curating "core competency" data (high-quality, representative datasets) and supplement it with broader but lower-quality data. Maintaining this balance requires constant measurement (benchmarks, human evaluations) and simplifying the architecture when needed.
