TRIAGE: Evaluating Prospective Metacognitive Control in LLMs under Resource Constraints
Pith reviewed 2026-05-14 19:24 UTC · model grok-4.3
The pith
Language models lack the ability to prospectively plan task selection and compute allocation under fixed token budgets.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
TRIAGE measures prospective metacognitive control by requiring models to commit to a single ordered plan that jointly encodes selection, sequencing, and per-problem token allocation under a budget calibrated to the model's baseline cost; the resulting triage efficiency ratio quantifies how closely the plan matches the value an oracle with full knowledge of solvability and cost would achieve.
What carries the argument
The TRIAGE efficiency ratio, computed by scoring a model's committed plan against an oracle that knows each problem's solvability and exact cost for that model.
If this is right
- Agents built on models with stronger prospective control could complete more problems within the same token budget by avoiding low-yield tasks.
- The measured capability is distinct from single-task accuracy and directly affects deployment cost in queued problem settings.
- Both reasoning-enabled and base models show the same deficit, suggesting the gap is not fixed by adding chain-of-thought at inference time.
- Closing the gap would require training objectives that reward joint planning over isolated problem solving.
Where Pith is reading between the lines
- Models that improve on TRIAGE could be paired with lighter verification steps, freeing tokens for harder problems.
- The framework could be extended to dynamic queues where new problems arrive after partial execution.
- Training data that includes explicit triage examples might narrow the gap faster than accuracy-only fine-tuning.
- Human performance on analogous triage tasks could serve as an upper bound for future model comparisons.
Load-bearing premise
An oracle that already knows the model's success rate and cost on every problem supplies a fair and unbiased benchmark without introducing hindsight bias or selection effects from the budget calibration.
What would settle it
A model that repeatedly produces plans whose achieved value reaches at least 85 percent of the oracle optimum across held-out task pools of varying difficulty would falsify the reported gaps.

read the original abstract
Deploying language models as autonomous agents requires more than per-task accuracy: when an agent faces a queue of problems under a finite token budget, it must decide which to attempt, in what order, and how much compute to commit to each, all before any execution feedback is available. This is the prospective form of metacognitive control studied for decades in human cognition, yet whether language models possess it remains untested. We introduce TRIAGE, an evaluation framework in which a model receives a task pool and a token budget calibrated to its own baseline cost, and commits to a single ordered plan that jointly encodes selection, sequencing, and per-problem allocation. Plans are scored against an oracle with full knowledge of the model's solvability and cost on each problem, yielding a triage efficiency ratio on a common scale. We evaluate frontier and open-source models, with and without reasoning enabled, across competition mathematics, graduate-level science, code generation, and expert multidisciplinary knowledge, and find that current language models exhibit substantial gaps in prospective metacognitive control, revealing a previously unmeasured capability dimension with direct implications for resource-efficient agent deployment.

Referee Report
Summary. The manuscript introduces TRIAGE, a framework to evaluate prospective metacognitive control in LLMs. A model is given a task pool and a token budget calibrated to its baseline cost on those tasks. It must produce one ordered plan encoding selection, sequencing, and allocation decisions before any execution. The plan is scored against an oracle possessing full knowledge of the model's solvability and costs per problem, producing a triage efficiency ratio. Evaluations across math, science, code, and knowledge tasks indicate substantial gaps in current models' prospective control abilities.
Significance. If the central findings hold, the work identifies a new, previously unmeasured capability dimension relevant to resource-efficient deployment of LLMs as agents. The framework offers a concrete, scalable method to quantify selection, sequencing, and allocation reasoning under constraints, with direct implications for practical agent systems. The multi-domain evaluation and comparison of frontier and open-source models with and without reasoning are strengths.
major comments (1)
- [Abstract] The triage efficiency ratio is defined against an oracle with complete knowledge of solvability and per-problem costs, while the model's plan is formed prospectively without feedback. This creates an information asymmetry that may cause the reported gaps to partly reflect the oracle's hindsight rather than a pure deficit in metacognitive control. The token budget is calibrated to the model's baseline cost on the evaluation task pool, which embeds task-specific statistics unavailable at planning time.
minor comments (2)
- The abstract reports high-level findings without specific quantitative results, error bars, or detailed task descriptions, which limits immediate assessment of effect sizes.
- Clarify whether the baseline cost measurement uses the same task pool or a held-out set to avoid circularity in calibration.

Referee: [Abstract] The triage efficiency ratio is defined against an oracle with complete knowledge of solvability and per-problem costs, while the model's plan is formed prospectively without feedback. This creates an information asymmetry that may cause the reported gaps to partly reflect the oracle's hindsight rather than a pure deficit in metacognitive control. The token budget is calibrated to the model's baseline cost on the evaluation task pool, which embeds task-specific statistics unavailable at planning time.
Authors: The information asymmetry is a deliberate feature of the evaluation design. The oracle establishes the theoretical maximum triage efficiency given the model's actual solvability and per-problem costs, providing a normalized measure of how closely the prospective plan approaches optimality. This approach is standard in planning and resource-allocation benchmarks to quantify deviation from the best achievable outcome under uncertainty. The gaps therefore capture limitations in the model's prospective selection, sequencing, and allocation reasoning. Regarding budget calibration, the total token budget is derived from the model's baseline costs on the pool to ensure realism and model-specificity; however, at planning time the model is given only the aggregate budget and task pool, with no per-task cost or solvability information disclosed. We will revise the abstract and methods section to explicitly clarify this design rationale and the oracle's role as an upper-bound reference. revision: yes
Circularity Check
No significant circularity in TRIAGE evaluation framework
full rationale
The paper defines the triage efficiency ratio by scoring a model's single pre-execution plan against an independent oracle that holds full knowledge of solvability and per-problem costs on the task pool. Token-budget calibration to the model's measured baseline cost on the same pool serves only as normalization to place results on a common scale; it does not embed the target ratio or any fitted parameter into the reported metric. No equations, self-citations, or uniqueness claims reduce the central result to a definition, a prior fit, or an author-supplied ansatz. The evaluation draws on external benchmarks across mathematics, science, code, and knowledge domains, keeping the derivation self-contained against verifiable external oracles.
