Fifth installment of Oleg Efimov's Claude Code series. ## Author's thesis (Adler Q1+Q2) **What is the article about?** How model choice and reasoning-effort level are two separate routing decisions in Claude Code, and how to match both to task uncertainty, cost, latency, and consequence. **What is being argued?** Defaulting to the largest model and highest effort wastes cost and latency on routine work; the article recommends faster models for bounded search and routine tasks, higher effort reserved for ambiguous architecture and hard debugging, and pinning delegated model choices when cost or quality specifically matters. ## Key arguments (≤3) 1. **Use faster models for bounded search and routine work** — model tier should scale with task uncertainty, not default to maximum. 2. **Reserve higher reasoning effort for ambiguous architecture and hard debugging** — effort is a distinct dial from model tier and should be spent where the problem is genuinely open-ended. 3. **Pin delegated model choices when cost or quality matters** — leaving model selection to defaults in a multi-agent or subagent setup risks unpredictable cost/quality tradeoffs. ## Claim atoms ### Model and effort are independent routing axes > [!quote] ID:rw_01kz7st3bcdjcz1xmrj86mv323 > Model and effort are independent axes Where/why: the article's central distinction, framing the rest of the routing advice. ### Reserve higher effort for ambiguous, high-stakes work > [!quote] ID:rw_01kz7st57p734nkvww3shkbbgk > Sonnet at medium for routine work Where/why: gives the concrete default the article recommends for the common case. ### More effort isn't free — it costs latency and money even when it "sounds better" > [!quote] ID:rw_01kz7st4acxq1ewn6pw69r77vs > More effort always sounds better Where/why: names the intuitive mistake the article is correcting. ## Permanent candidates - The deep-read's generic candidate duplicates the "enforceable layer" note already in the vault. The article's genuine, topic-specific claim (model tier and reasoning effort are separate routing decisions) is already substantially covered by an existing Permanent note on cost-architecture routing — connecting rather than duplicating. ## Processing checklist - [x] Checked existing Permanents for this article's model/effort routing claim — found a close match, linked rather than duplicated - [x] Connect into the relevant MOC — [[3. Resources/MOCs/AI Cost & Tokenomics MOC]] ## Links - [[3. Resources/MOCs/AI Cost & Tokenomics MOC]] — model/effort routing is a direct cost-control lever this MOC already tracks - [[3.
