chapter 44
cnns, transformers, and useful llm internals
architecture literacy for builders: convolution, attention, tokens, decoding, kv cache, quantization, and what those choices do to cost and behavior.
cnns, transformers, and useful llm internals
Architecture literacy helps builders predict cost and behavior. This chapter keeps CNNs, token budgets, attention, decoding, KV cache, and quantization grounded in the tradeoffs a product builder actually reviews.
The exercises use small Python dictionaries and lists so every check can run in the browser. Real-world tools may be larger, but the review shape stays the same: input, decision, evidence, blocker, and next step.
By the end of the chapter, learners should be able to turn this topic into a concrete handoff instead of a vague model claim.
