In this fast moving field, it’s really handy to think of all the AI tools and advancements as pokemons - and you are Ash. Gotta catch ‘em all.
It’s not about having a shiny new skill or knowing this framework or that AI tool. It’s about gaining perspective. Piecing things together. Knowing what’s possible and having a mental model of what’s really achievable (while understanding current limitations).
You don’t need to master them - hell, not even be decent at them. Just have a mental model of what’s possible and what’s not with each one.
And the stack is deep. Even before you get to anything fancy, just taking LLMs to production involves a ridiculous number of decisions:
- Protocols: MCP, A2A - do you even know what problem each solves and when you’d reach for one?
- Frameworks: LangChain/LangGraph vs Google ADK vs Pydantic AI - each has a different philosophy about how you structure agent logic
- Routing and gateways: OpenRouter vs LiteLLM - do you want a hosted abstraction or something you run yourself? What does that tradeoff actually look like?
- Observability: OTEL-compatible clients vs something like LangSmith (which is also OTEL-compatible, by the way) - how do you even think about tracing chains and agent runs?
- Model releases: a new model drops every few weeks - knowing roughly where each one sits on the capability/cost curve matters more than knowing the benchmarks cold
- Best practices: prompt caching, batching, context window management, structured outputs - small things that compound into real cost and latency differences
- Open source deployment: vLLM vs SGLang - when does it even make sense to run your own inference? And once you do, are you optimizing for throughput or latency? Do you know what those metrics actually mean in your context?
- Cost estimation: what are you even measuring? Tokens? GPU hours? What should you actually care about?
That’s just the infrastructure layer. We haven’t even talked about evals, fine-tuning, or what happens when your agent does something unexpected in production.
The point isn’t that you need answers to all of this. The point is that your way of viewing problems completely changes based on your exposure to the landscape. It’s like hot-loading a mental map instead of starting cold every time you hit a new problem.
Often it’s the inertia - not knowing where to even start - that stops people from doing incredible things with these tools. Not the complexity of the problems themselves. Having the Pokedex means you at least know which pokemon to reach for.
