Penn]] ## Highlights - By heavy context penalty, I mean this reading and writing process of documentation, which is a good thing for AI to do, is very token heavy. It's very memory heavy. It consumes a lot of working memory to read and write big text files. That's why writing code is relatively inexpensive. Writing a book is very expensive with these tools because you're having to keep a lot of documents and a lot of text in memory and recycle it frequently. Don't do that. You are going to spend so much money unnecessarily. My suggestion for multi-agent orchestration is use a lightweight cheap model, ideally on something like a token plan, that is tuned and optimized for those kinds of tasks. So this could be things like Nvidia's Nemotron models, which are super cheap and still pretty smart. Nemotron Super, Nano and Ultra just came out as of June 2026. Very good model, lightweight, has a 1 million token context memory. And darn close to free in terms of processing costs.

Corrects the standard intuition: documentation looks trivial and behaves like book-writing; code looks hard and is cheap. Multi-agent multiplies it because each agent reloads. - Tags: atom/atomic/z1, ai-cost, tokenomics - Tasks like documentation, there are existing plain text systems that you can use with command line tools that do not require you to use an LLM for a lot of stuff like indexing. You can use an abstract syntax tree. You can use something like graph finder, or use it with a super lightweight model. There's so many ways to accomplish what you're trying to do, which is create documents, without using the most expensive models. So that'll be my suggestions. Use the lightest cheapest model based on the task. Have multiple cheap models handy that you can price compare or use based on budget. And do your best to not use AI for tasks that are not well suited for AI. Thanks for the question. ([View Highlight](https://read.readwise.io/read/01kz3xmqmp0kyavtzpedzrjmz4)) - Note: The best point, given the least airtime: before choosing WHICH model, ask whether the step needs a model at all. Indexing/structural parsing have mature deterministic tooling. The cheapest token is the one you don't spend — and it's the least self-serving advice in the piece. - Tags: deterministic-tooling, cost-efficiency, atom/atomic/z3
