The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The load-bearing object is a programmatic instruction template generator. It fills placeholders in 24 hand-designed meta templates with position-specific synonyms, and a sentence-pattern tree organizes those meta templates by grammatical structure; a weight-accumulation sampling algorithm then makes every one of the 15K generated instruction templates roughly equally likely to appear. This keeps the training set's size and content fixed while letting the number of distinct templates vary from 10 to 15K, which is what makes the scaling curves interpretable. All twelve training runs use Low-Rank Adaptation (LoRA) on the same LLaVA-1.5 base checkpoints.
What would settle it
Train the 7B model with 5K templates but give each template the same exposure count as in the 10-template run (by shrinking the dataset or repeating the pool), and see whether the 5K peak persists; if the peak moves, the inverted-U shape is driven by exposure frequency rather than template count.
Extended reading notes
Core claim
The paper's central discovery is that MLM capability is a non-monotonic function of instruction-template scale. With the training set held at 665K samples, increasing template count from 10 to 15K produces an inverted-U average-performance curve on five VQA benchmarks. The optimal scale depends on model size: LLaVA-1.5-7B peaks at 5K templates, while LLaVA-1.5-13B peaks at only 100 templates. Models trained at their optimal template scale outperform the original data-only LLaVA-1.5 models by up to 10 percent and achieve the best overall performance relative to similar-scale models trained on up to 75.19 times more instruction data, while also reducing the spread between best and worst accuracy across evaluation templates.
Load-bearing premise
The load-bearing premise is that holding the training set at 665K samples while varying the number of templates isolates the template-scaling effect; but with few templates each one is seen many more times, and with many templates most are seen only briefly, so the curve could instead reflect a repetition-diversity tradeoff or evaluation familiarity.
Editorial extensions
If this is right
- Template count becomes a tunable hyperparameter of visual instruction tuning; adding more templates is not automatically better.
- At the optimal scale, template augmentation can substitute for much larger instruction datasets, saving data collection and compute.
- The optimal template scale is model-dependent, with stronger models needing fewer templates.
- Training with the right template scale reduces performance fluctuation across prompt phrasings, which should make MLM evaluation and deployment more stable.
- A medium-scale template pool is enough, so an exhaustive large-scale template search is unnecessary.
Reading between the lines
- Because the total sample count is fixed, varying template scale also varies how often each template is seen during training; separating that repetition effect from template count would be a direct test of the paper's mechanism.
- If this non-monotonic pattern extends to text-only language models, template count would become a cheap scaling axis for instruction tuning alongside data size and model size.
- The generator varies lexical and syntactic surface form only; template families that change semantics, language, or reasoning style may have a different optimum.
- Holding per-template exposure frequency constant (by subsampling or repeating templates) while changing the number of distinct templates could yield a sharper design rule than the current inverted-U curve.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper investigates how the number of distinct instruction templates used during visual instruction tuning affects multimodal language model (MLM) performance. The authors build a programmatic generator that can produce roughly 15K instruction templates from 24 meta templates, and they fine-tune LLaVA-1.5-7B and LLaVA-1.5-13B on six versions of the same 665K-sample instruction dataset, using 10, 100, 1K, 5K, 10K, and 15K templates. Performance is measured on five VQA benchmarks, each evaluated with 100 in-domain templates, 25 manually written out-of-domain templates, and three simple templates. The central empirical claim is that MLM performance is non-monotonic in template scale, peaking at an intermediate number of templates: 5K for the 7B model and 100 for the 13B model. The paper further claims that models trained at these optimal scales outperform comparable models trained on up to 75 times more instruction data, while also reducing performance variance across instruction templates.
Significance. If the main claim were established, it would be practically significant: it would show that visual instruction tuning can be improved substantially without adding new training data, and that template diversity is not a quantity to be maximized blindly. The generator itself is a useful contribution, and the systematic sweep over six template scales across two model sizes is a reasonable way to probe the question. The variance-reduction analysis across templates is also valuable and is the kind of robustness evidence the field needs. However, the central scaling conclusion is currently undercut by a design confound between template count and per-template exposure frequency, by an evaluation whose statistical precision is too low for the claimed peaks, and by selection of the optimal scale on the same benchmarks used for the final comparison. The paper is therefore interesting but the headline result is not yet supported.
major comments (4)
- [Sec. 3.1] The fixed-size design confounds template scale with per-template exposure frequency. The text states that the six template-augmented versions 'maintain the same size as the original' 665K dataset while using 10, 100, 1K, 5K, 10K, and 15K templates. Consequently, with 10 templates each template appears roughly 66,500 times, while with 15K templates each appears only about 44 times. The rise-then-fall curve in Figure 4 may therefore reflect a repetition-diversity tradeoff rather than a template-scaling law. To support the central claim, the authors should either vary template count while holding per-template exposure roughly constant (for example, by scaling total dataset size with template count, or by controlling the number of samples per template) or report per-template exposure and show that the non-monotonic trend is not explained by it.
- [Sec. 3.1] The in-domain evaluation is not consistently 'in-domain' across training conditions. The paper says the 100 in-domain evaluation templates 'have encountered during training,' but in the 10-template training condition at most 10 of those templates can have been seen during training; for the 100-template condition the overlap depends on whether the evaluation templates are exactly the training templates. This means the in-domain curves in Figures 3 and 4 partly measure train/evaluation overlap rather than a systematic effect of template scale. The authors should specify how the 100 evaluation templates relate to the template pool used for each training run, and report the actual overlap for each condition.
- [Sec. 3.1 and Sec. 3.2] The evaluation has no error bars and no repeated sampling. The protocol randomly selects 100 data points per benchmark according to category distribution, once, with no seeds or repeated trials reported. For 100 binary-accuracy items the standard error can be as large as 5 points, and many of the between-condition differences in Table 1 are only a few points. The claims that the 7B model peaks at 5K templates and the 13B model peaks at 100 templates, and that these peaks are robust, require confidence intervals, repeated subsampling, or evaluation on the full benchmark sets. Without this, the specific peak locations may be noise.
- [Sec. 3.2 and Sec. 4.2] The optimal template scale is selected on the same benchmarks used to report the final gains. The peak scale is identified from average performance on the five benchmarks in Figure 4, and Table 1 then uses those same benchmarks to claim that the selected 5K/100-template models outperform baselines. This is a form of test-set selection and inflates the reported gains. The authors should either hold out a validation set for scale selection, report results for all six scales in the comparison table, or use an additional benchmark suite for the final claim that the optimal-scale model is the best overall.
minor comments (5)
- [Sec. 3.1] The phrase 'randomly select 100 data points for each dataset according to their category distribution' is ambiguous: it should say whether this is a stratified sample of 100 total items or a fixed number per category, and it should report the random seed used.
- [Table 1] The column header 'OverallS ID OOD' is difficult to parse; the table would be clearer with a separate 'Overall' column followed by clearly separated 'S', 'ID', and 'OOD' subcolumns for each benchmark.
- [Figures 3 and 4] The caption text 'Optimal template scale vary across different datasets' has a subject-verb agreement error and should be 'varies'; the same issue appears in the main text.
- [Sec. 5 and References] The related work cites the authors' own Provision paper (Zhang et al., 2024b) for the benefit of multi-template training, but the present paper's generator and augmentation recipe appear closely related to Provision; the authors should clarify the specific incremental contribution beyond that prior work.
- [Table 1] The notation '50M' for Qwen-VL-7B is inconsistent with '665K' and '760k' used elsewhere; please use uniform units (e.g., 50M, 760K, 665K) and clarify whether the number refers to instruction-tuning samples.
Circularity Check
No significant circularity: the scaling finding is an empirical measurement, not a derivation, and the self-citations are contextual rather than load-bearing.
full rationale
The paper's central claim is an empirical scaling curve: six training runs with 10/100/1K/5K/10K/15K templates on fixed 665K data are evaluated on five external benchmarks, and the paper reports the measured optimum (Sec 3.2, Figures 3-4). No quantity is fitted to a target and then announced as a prediction; the 'optimal template scale' is an observed peak, and the subsequent comparison in Sec 4 reports direct measurements. The only in-paper derivation, the uniform-sampling property of the sentence-pattern tree, is self-contained: Algorithm 1-2's weighted sampling makes each leaf probability w(leaf)/w(root), and the uniform placeholder choice gives each concrete template probability 1/w(root) (Sec 2.2). This does not rely on any cited result. The self-citations (Zhang et al. 2024b for multi-template training; Zhang et al. 2024a for template sensitivity/evaluation) are motivational and methodological; neither is used to derive the scaling law, which is established by the paper's own experiments. The reader-identified confound (fixed total size couples template count with per-template exposure frequency, and the 100 'in-domain' evaluation templates cannot all have been encountered by the 10-template training runs, Sec 3.1) is a validity/overfitting concern about what the curve isolates, not a circular reduction: the numbers are measurements, not definitional consequences. It should be fixed or discussed, but it does not make the derivation circular.

Current multimodal language model (MLM) training approaches overlook the influence of instruction templates. Previous research deals with this problem by leveraging hand-crafted or model-generated templates, failing to investigate the scaling effect of instruction templates on MLM training. In this work, we propose a programmatic instruction template generator capable of producing over 15K unique instruction templates by filling randomly sampled positional synonyms into weighted sampled meta templates, enabling us to comprehensively explore MLM's performance across various template scales in the training process. Our investigation into scaling instruction templates for MLM training demonstrates that MLM capabilities do not consistently improve with increasing template scale. Instead, optimal performance is achieved at a medium template scale. Models trained with data augmented at the optimal template scale achieve performance gains of up to 10% over those trained on the original data and achieve the best overall performance compared with the similar-scale MLMs tuned on at most 75 times the scale of our augmented dataset. The code will be publicly available at https://github.com/shijian2001/TemplateScaling.
