ModelsKimi K3 vs DeepSeek V4 Pro: Doing the 17x Price Arithmetic
K3 costs about seventeen times more per output token than DeepSeek V4 Pro. Here is the break-even calculation that decides whether that is worth paying.
ReadNotes on models, agents, and what inference costs
Practical writing for developers building with large language models — how they work, how to pick one, and how to keep the bill predictable.

GuidesLLMs for Log Analysis Without Sending Them Your Logs
You cannot fit a day of logs in a context window and should not try. Template mining, diffing and sampling first — then a model on the reduced set where it earns its keep.

Local inference is free at the margin and expensive everywhere else. Work through the memory arithmetic, the real break-even, and where each option genuinely wins.
