Infinity-Parser2 Technical Report
The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
Core claim
The central claim is that one vision-language model can map a document page to a structured, reading-ordered representation — JSON with per-element categories, bounding boxes and text, or Markdown/HTML/LaTeX — as accurately as pipeline systems, provided it is first trained on a large corpus of exact synthetic labels and then refined with a reward that credits where an element is and what it says separately. On the paper's evidence, this is realized by the Pro model's top scores on olmOCR-Bench and ParseBench and its strong results on layout analysis, table parsing, math formulas, charts, chemical structures, and document QA. The authors' own framing: the DOM-based synthesis engine makes trai
What carries the argument
The load-bearing object is a DOM-based document synthesis engine. It uses a browser layout engine to typeset documents from a logical tree of typed elements, then reads bounding boxes, reading order, element categories, and structured text directly off the laid-out tree, so pixels and labels are consistent by construction. Around it sits a four-stage data flywheel: evaluate the current model on a fixed benchmark suite, mine its weak cases into tags, collect and synthesize new data targeting those tags, fine-tune, and repeat until gains saturate. The second mechanism is a reward router for joint reinforcement learning: each of eight tasks is scored by its own verifiable metric, the spatial an
Load-bearing premise
The flywheel's guarantee that evaluation-benchmark samples never enter the training pool: if benchmark-like pages leak into Infinity-Doc2-5M, or if the training distribution is tuned to the benchmarks' specific layouts, the reported state-of-the-art numbers would not reflect general document parsing.
What would settle it
Take the released Pro model, evaluate it on a freshly collected document set that was never part of olmOCR-Bench, ParseBench, or the training corpus (for example, recent legal filings or handwritten archives), and search Infinity-Doc2-5M for near-duplicates of benchmark pages. If accuracy on the fresh set falls far short of the reported margins, or if duplicate pages are found, the flywheel's benchmark-safety claim is falsified.
If this is right
- If the reported scores hold, the released open-weight Pro model is the strongest open end-to-end document parser among the compared systems on both olmOCR-Bench and ParseBench.
- The two variants give a concrete accuracy-versus-latency trade: Flash scores about 1.6 points lower on olmOCR-Bench but runs about 3.7x faster, so high-volume document pipelines can choose the cheaper model without leaving most of the quality behind.
- The 5M-sample corpus, the synthesis code, and both model weights are released, which means the annotation bottleneck the paper targets is directly lowered for anyone training a document parser.
- Because the same instruction-selected model handles layout, tables, math, charts, chemical formulas, and document VQA, users no longer need a separate system for each structured output type.
- The spatial component of the reward demonstrably feeds back into text fidelity: adding per-category mIoU to the textual reward improved both layout and parsing scores in the ablations, tying localization accuracy to reading-order quality.
Where Pith is reading between the lines
- The DOM-as-single-source-of-truth trick is not limited to documents: any structured output that can be rendered from a typed tree (diagrams, music scores, CAD, timeline graphics) could get cheap exact annotations by registering a renderer, an extension the paper gestures at but does not test.
- The disentangled spatial-plus-textual reward is a general recipe for any detection-and-recognition task; a testable extension would be applying it to forms processing or receipt extraction and checking whether localization accuracy improves downstream field-level extraction.
- The flywheel's fixed benchmark suite means the reported gains are measured on the same task distribution the loop optimizes against; running the same loop on a freshly built benchmark from an unseen domain would test whether the per-round gains transfer or are specific to the suite.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper presents Infinity-Parser2, a family of end-to-end document parsing VLMs built on Qwen3.5 backbones. It combines a DOM-based synthesis engine and a data iteration flywheel to construct a 5M-sample bilingual corpus (Infinity-Doc2-5M), then trains the models with SFT followed by multi-task RL using verifiable task-native metrics as rewards. The Pro variant claims state-of-the-art results on olmOCR-Bench (87.6) and ParseBench (74.3), while the Flash variant offers a 3.68x throughput gain over the prior Infinity-Parser-7B. The paper includes extensive evaluations across layout analysis, table/formula/chart/chemical parsing, document VQA, general multimodal understanding, and a downstream financial-information-extraction task, along with ablations on resolution, reward design, data flywheel rounds, and training strategies.
Significance. If the reported results hold, the paper makes a substantial contribution: an open end-to-end document parser with state-of-the-art scores on two recent benchmarks, a publicly released 5M-sample corpus, and a transparent metric-as-reward RL recipe. The design is methodologically clean in several places: the reward is explicitly the evaluation metric for each task, the DOM-based synthesis engine produces exact labels by construction, and the ablations are well structured and informative. The limitations section is candid about bilingual scope, pseudo-label noise, and formatting losses. However, the headline SOTA claim depends on two unverified links: the flywheel's non-contamination guarantee (Sec. 3.1), and the comparability of the mixed re-scored/cited baseline numbers in the main tables. These need to be strengthened before the claim can be considered settled.
major comments (3)
- [Sec. 3.1 (Stage 1) and Table 10] The claim that benchmark samples are 'never reused as training data' is asserted but not supported by any deduplication or overlap audit. The flywheel evaluates on the fixed suite (olmOCR-Bench, ParseBench, OmniDocBench), mines weakness tags from low-scoring samples, and then drives web scraping and synthesis with those same tags. Table 10 attributes a 54.9-point gain on olmOCR-Bench (28.4 to 83.3) to pseudo-labeled web data. If any pages resembling the benchmark distribution enter the training pool, or if the tag-driven acquisition implicitly selects for benchmark-specific layout/domain features, the headline 87.6/74.3 numbers would be inflated. Please report a concrete contamination analysis, e.g., near-duplicate detection (hash or embedding similarity) between Infinity-Doc2-5M and each benchmark's test pages, and/or a holdout evaluation on a benchmark never used in the flywheel loop.
- [Tables 2, 4, 5, 7 and Sec. 5.1] The headline comparisons mix re-scored baselines (marked '*') with numbers cited from original reports, and the main SOTA tables lack error bars/confidence intervals except for olmOCR-Bench. For example, the ParseBench margin (74.3 vs. 70.1) is a 4.2-point gap on a roughly 2,000-page benchmark, and OmniDocBench-v1.6 is reported as a point estimate. The text says re-evaluation follows 'officially recommended' prompts, but the reader cannot tell which cells are re-scored and which are quoted, and prompt/output-format differences can shift scores materially. Please state for every cell which source applies, report standard errors or bootstrap CIs for the key comparisons, and make the evaluation code/prompts available.
- [Sec. 5.7, Table 14] The FinIE downstream evaluation uses 'Infinity-Parser2-Flash*' — a variant further finetuned on internal financial tables — to claim the highest F1 (95.75). This is not one of the two released models (Flash/Pro), so the result does not directly support the paper's claims about the released system. Clarify whether the finetuned checkpoint will be released, or reposition this result as an illustration of the architecture's headroom rather than a property of the released models.
minor comments (5)
- [Sec. 4 (before Figure 4)] There is a stray placeholder text '在此处键入公式。' in the manuscript; please remove it.
- [Table 3 and Sec. A.1] The five broad categories used in the mIoU protocol should be explicitly listed in the table caption, and the nonstandard label notation for D4LA should be explained.
- [Sec. A.1 (CoSyn-Chemical)] CoSyn-Chemical validation has only 128 image-text pairs; this should be stated in the main text near Table 6, since the reported differences of a few InChI points are within sampling noise.
- [References] Reference [14] is cited for the CoSyn-Chemical benchmark, but the reference describes code-guided synthetic data generation in general; please cite the actual benchmark release or clarify the source.
- [Figure 1 (bottom panel)] The 'N/A' entries in the multi-task panel are unexplained; add a note describing why certain cells are not applicable.
Circularity Check
Flywheel tunes training data to the reported benchmarks; the headline SOTA is the fitted target rather than an independent prediction.
specific steps
-
fitted input called prediction
[Sec. 3.1 (Data Iteration Flywheel), Stages 1–4; Sec. 4.3.2 (metric-as-reward)]
"At each flywheel iteration, the current parsing model is evaluated on a multi-task benchmark suite covering end-to-end document parsing, layout analysis, and element-level parsing. ... the accumulated weakness tags act as a demand signal that flows into Stage 2, where targeted acquisition is performed on disjoint, training-safe sources matching the same weakness profile. ... The synthesis engine (whose corpus selection, layout templates, and rendering parameters are conditioned directly on the Stage 1 tags) ... Iterations continue until benchmark gains across consecutive rounds become negligib"
The headline olmOCR-Bench/ParseBench scores are the same suite whose per-sample failures are mined in Stage 1 and converted into weakness tags; those tags drive data mining and synthesis-conditioning in Stages 2–3, and the loop stops when gains on this fixed suite saturate (Stage 4). Thus the reported SOTA numbers are the optimization target of the flywheel, not an independent evaluation. Even if individual benchmark pages are 'never reused,' the benchmark's weakness profile is the generative prior for the training data, so the benchmark score is fitted to the benchmark by construction. The RL stage compounds this: 'metric-as-reward' optimizes the exact metrics on which tasks are judged, further reducing the 'prediction' to the fitted objective.
full rationale
The principal circularity is the flywheel's use of the reported benchmark suite as both the diagnostic signal and the convergence target. Stage 1 mines weaknesses from olmOCR-Bench/ParseBench/OmniDocBench; Stages 2–3 acquire and synthesize data 'matching the same weakness profile' with synthesis 'conditioned directly on the Stage 1 tags'; Stage 4 trains until 'benchmark gains ... become negligible.' The RL stage uses 'metric-as-reward,' so the model is explicitly trained to maximize the same metrics by which it is judged. This makes the headline SOTA numbers fitted outputs of an optimization loop rather than independent predictions of general parsing ability. This is partial circularity, not total: the synthesis engine, multi-task RL recipe, and held-out benchmarks for elements (PubTabNet, UniMERNet, ChartQA, DocVQA, etc.) provide substantial independent content, and the cited prior work (Infinity-Parser, Infinity-Doc-400K) is used as a data/teacher source rather than as a uniqueness argument. The 'never reused' assertion is unverified, and even if true, the weakness-profile conditioning is a distribution-level form of fitting. Score 6 rather than 8 because the exact score still depends on model capacity, data quality, and independent benchmarks; but for the headline numbers, the derivation chain is circular.

We present Infinity-Parser2, a large multimodal model that couples a controllable data-synthesis pipeline with multi-task reinforcement learning for end-to-end document parsing, addressing the persistent scarcity of faithfully annotated parsing corpora. Our contributions are threefold. First, we build a scalable synthesis engine, pairing a controllable rendering framework with an iterative refinement loop, and use it to construct and open-source Infinity-Doc2-5M: a 5-million-sample bilingual (Chinese/English) corpus spanning diverse document types, annotated with element bounding boxes, canonical content forms (Markdown, HTML, LaTeX, SMILES, structured charts), and full-page reading order. Second, we introduce a verifiable, multi-task reward system that enables Joint Reinforcement Learning across eight co-trained objectives (document parsing, layout analysis, table parsing, math formula parsing, chart parsing, chemical formula parsing, document VQA, and general multimodal understanding), unifying perception, structure, and reasoning in a single optimization signal. Third, we release two variants under a shared architecture: Infinity-Parser2-Flash, optimized for low-latency inference with a 3.68x throughput gain over Infinity-Parser-7B, and Infinity-Parser2-Pro, engineered for precision-critical settings. Infinity-Parser2-Pro reaches state-of-the-art 87.6% on olmOCR-Bench and 74.3% on ParseBench, surpassing DeepSeek-OCR-2, PaddleOCR-VL-1.5, and MinerU2.5, with strong generalization to charts, chemical formulas, and document VQA.
