Architecture notes, leadership thinking, and things I learned the hard way.
Dense vs. MoE Models Explained
A 30B model with 3B active parameters still needs room for its full weights. Here is how dense and mixture-of-experts models differ and what total parameters, routing, memory, and compute mean for local AI.

Prefill vs. Decode
Tokens per second is not one measurement. Prefill is the work of reading the prompt; decode is the work of generating output. Understanding both explains TTFT, output speed, bandwidth, compute, context length, and benchmark results.

Local Coding Models by Memory
From 4 GB to 512 GB, the right local coding model is the one that leaves enough memory for context, KV cache, and the runtime—not the largest file that barely loads.

LLM Quantization Explained
FP16, BF16, FP8, Q8, Q4, GGUF, KV cache, prefill, and decode all describe different parts of local AI. Here is how they fit together—and what they mean for memory, speed, and model quality.
