How do you scope a custom LLM? 📃 Have a specific goal: search? summarize? generate? Understand the resource constraints: proof of concept vs horizontal model (mixture of experts) vs vertical model (master many domains). The more ambitious the goal, the more likely you need tuning.

What are the tradeoffs between popular Foundational Models? 💱 In general, with enough context and tuning, models of similar size/complexity converge in quality. version control (deterministic testing), cost control, enterprise support, hosting, and avoiding getting rugged! LLMs = Chaotic = easy to break behavior.

Context is the easiest way to format a model's behavior. Simply *append* relevant information to every single user's request (i.e., exploit large context windows) Be careful: these can be *misleadingly* good in proof of concepts, but struggle to be aMaZinG in the wild https://warpcast.com/charliemktplace/0xbdce4dd1
