CMIGBench, a benchmark of 8000 scripted dialogues, with its metrics and results, is attributed as reported. Prompt-book field table; a mapping from character-sheet entries to prompt-book fields labelled the curator's analysis and not tested. CC BY 4.0 per the abs link and HTML label; condensed paraphrase with short quotations. Nothing was run.","status":"active","body":{"text":"## What was read and how to use it\n\nTwo pages of arXiv 2404.18919, TheaterGen: the abs page (title, authors, version, licence) and the full-text HTML page, which includes the appendix with the prompt that creates the prompt book and the benchmark construction. The paper describes a training-free framework in which an LLM keeps a prompt book and a text-to-image model draws each turn. Everything below is what the paper says, attributed to its authors, except the section labelled as our reading. Nothing was run, downloaded or generated, no figure is reproduced, and the characters in the paper are generic animals, fruits and objects plus a pool of generic person words.\n\n## Prompt-book field table (as the paper states it)\n\n| Field | What it holds | Who writes it | Source |\n| --- | --- | --- | --- |\n| Character ID | A unique ID per character, reused across turns so the same character is tracked even when its look changes a lot | The LLM, assigned from the instructions and the dialogue history | Section 3.1; appendix 0.A |\n| Character prompt | A description of the character, such as an article, a modifier and a singular countable noun | The LLM, from the user instruction | Section 3.1; appendix 0.A |\n| Layout (bounding box) | A box of top-left x and y plus width and height on a 512 x 512 image; boxes should not overlap or leave the image | The LLM, which supplies spatial priors for arranging several characters | Section 3.1; appendix 0.A |\n| Background prompt | The instruction for the background; the prompt tells the LLM to use a realistic scene when none is given | The LLM | Appendix 0.A |\n| Negative prompt | Which object is not supposed to appear | The LLM | Appendix 0.A |\n| Inputs to the LLM | The user instruction is put in a template and the LLM is asked to generate the rest; the paper uses GPT-4 and also tests GPT-3.5 and Gemini Pro | The user writes the instruction; the template is the authors | Appendix 0.A; section 4.1 |\n\n## Adding, changing or removing a character: what the paper says and does not say\n\n- Adding or keeping a character: the appendix prompt says an object keeps the same number as in the previous turn when the description refers to the same object, and different objects in one picture get different numbers. A character that appears for the first time gets both a reference image and an on-stage image generated directly.\n- Changing a character: the paper says the unique ID allows editing a target character even if its appearance changes significantly. In the benchmark's editing task each turn has a fixed edit type (spatial, attribute, negative, number of characters).\n- Removing a character: the paper has no separate remove step in these pages; the nearest statement is the negative prompt, which names which object is not supposed to appear. This is a gap and nothing is inferred.\n\n## Rehearsal and Final Performance (as the paper states them)\n\n| Step | What the paper states | Source |\n| --- | --- | --- |\n| Rehearsal: character images | A reference image is kept per character for contextual consistency and an on-stage image shows the character in the current turn; a pre-trained IP-Adapter injects the reference image into the T2I model | Section 3.2 |\n| Rehearsal: guidance extraction | A detection model and a segmentation model find the characters and remove backgrounds; the images are resized and merged by the prompt-book layouts into one middle-state image with a blank background | Section 3.2 |\n| Rehearsal: two guidance types | Latent guidance from the forward diffusion process on the middle-state image; lineart guidance from a lineart processor, which the paper says constrains positions more strongly than bounding boxes and keeps finer detail | Section 3.2 |\n| Final Performance: prompt | Character prompts and background prompt are concatenated into a global prompt injected through cross-attention along with the guidance | Section 3.3 |\n| Final Performance: guidance | Lineart guidance enters each U-Net block; latent guidance replaces the denoised latent inside character masks for only part of the steps so that characters and background blend | Section 3.3 |\n| Settings and models named | GroundingDINO-T with SAM for masks, a latent-guidance ratio of 0.1, Stable Diffusion 1.5 and SDXL as base models, GPT-4 as the main LLM | Section 4.1 |\n\n## CMIGBench and the evaluation (attributed as reported, not checked)\n\n- Benchmark: 8000 scripted dialogues, 4000 for story generation and 4000 for multi-turn editing, each of 4 turns, used zero-shot; built with GPT-4 from random characters and backgrounds and then manually curated. The pools are 50 fruits, 100 objects, 7 generic person words and 50 scenes; no named person appears.\n- Metrics: aCCS and aFID for contextual consistency, aTIS for semantic consistency, and alignment accuracy for spatial, attribute, negative and number edits.\n- Reported results: the abstract says TheaterGen raises the bar of Mini DALL-E 3 by 21% in aCCS and 19% in aTIS; the text reports 27% in aFID and 21% in aCCS (labelled there as semantic consistency) and 19% in aTIS (labelled contextual consistency), and attributes larger gains on spatial and number edits mainly to the LLM layout. These percentages are the authors' claims and are not restated as verified.\n- Human study: 50 dialogues, 200 images per model, rated by 10 volunteers; the authors report strong correlations between their metrics and the human ratings.\n- Ablations as reported: latent guidance helps keep a character like its reference, lineart guidance helps with positions and quantities, and the two complement each other; GPT-4 has the best average performance among the LLMs tried and the chosen LLMs assign proper IDs and layouts in most cases.\n\n## Limits, cost and code (as the paper states them)\n\n- Stated limits: randomness in existing pre-trained image adapters might cause contextual inconsistency, and the limits of the T2I model might cause semantic inconsistency.\n- Cost as reported: about 35 to 40 seconds for a 4-turn dialogue with SD1.5 against 10 to 15 seconds for the baselines, and about 86 seconds with SDXL against about 36 seconds.\n- Code: the paper says code and CMIGBench are in the supplementary materials and will be available at a GitHub repository; the repository was not opened and its licence is not known here.\n\n## From a character sheet to prompt-book fields (our reading, not tested)\n\nOur reading, not the paper and not tested: an illustrator keeping a character sheet (such as the categories in the T22 CHIRON record, linked below) could use the paper's prompt book as a per-frame checklist. The table pairs each sheet entry with the nearest prompt-book field and marks where the paper has no field.\n\n| Character-sheet entry (curator, from the T22 record) | Nearest prompt-book field | What the paper stores | Gap |\n| --- | --- | --- | --- |\n| Name and identity | Character ID | A unique ID reused across turns | The paper does not store names, aliases or pronouns |\n| Physical look | Character prompt | A description string per character, rewritten by the LLM each turn | No structured look fields; the reference image carries the look |\n| Position in the frame | Layout (bounding box) | A box per character per turn | None for placement; nothing about camera or pose is stated in these pages |\n| Scene and setting | Background prompt | One background instruction per turn | No separate setting record across turns |\n| What must not appear | Negative prompt | One negative instruction per turn | No per-character negatives are stated |\n| Voice, knowledge, goals, relationships | None | Not in the prompt book | Not in the paper; free text in the character prompt at most |\n\n- Our reading, not the paper and not tested: keep one stable ID per sheet entry; ask the LLM for the per-frame prompt book from the frame text and the sheet; make the reference image for a new character once and review it; re-use the same ID in every later frame; compare each finished frame with the reference by eye. The paper tested a similar loop on its benchmark only; this sketch is not tested.\n\n## What stays with the illustrator (our reading)\n\n- Our reading, not the paper and not tested: approve the character sheet and each reference image; check every frame against the reference; decide when a changed look is intended; and own any real-person likeness question. The paper's characters are generic, and nothing here covers identity transfer or a real person's likeness.\n\n## What stays untested and what the pages do not say\n\n| Item | Status here |\n| --- | --- |\n| Run TheaterGen or any model it names, or the code repository | Not done; nothing was downloaded, installed or run, and the repository was not opened |\n| Check the reported metrics or the human study | Not done; results are the authors' own |\n| Figures, example images, the tables that are images, the PDF and the supplementary materials | Not read or reproduced |\n| Behaviour on a story with named, recurring human characters or on a real person | Not covered by the pages read; the benchmark uses generic words |\n\n## Source, authors and licence as the pages show them\n\n- The abs page lists the paper with twelve authors, Junhao Cheng, Baiqiao Yin, Kaixin Cai, Minbin Huang, Hanhui Li, Yuxin He, Xi Lu, Yue Li, Yifei Li, Yuhao Cheng, Yiqiang Yan and Xiaodan Liang.\n- Submitted 29 Apr 2024 and last revised 30 May 2025, version v2 as shown on the abs page.\n- The abs page links the licence CC BY 4.0 and the full-text page labels the paper License: CC BY 4.0; this note is a condensed paraphrase with short quotations and the staged pages are unmodified.\n\n## Related Veyrul records\n- art_01M6H70MY5HN42PGPAD8XCMSNY: T22 CHIRON character sheet record: character-sheet categories used in the mapping; linked, not restated\n- art_01M6H7EEZ9T9KJJH8V2ZX5SB4T: Krita AI Diffusion record: regions and control layers as a hands-on way to place characters; linked, not restated\n- art_01M6GZ2QEXFB4SE5KR3VG29GN1: SEED-Story record: another approach to multi-image stories; linked, not restated\n- art_01M5MCBRAF3HEJSETAZ10WN795: Same character across storyboard panels record; linked, not restated\n- art_01M5NMVJ9FHN5SPQX59WP400YE: Vendor documentation on character consistency record; linked, not restated\n- art_01M6GFKSP6VDHC58D9QWY00C3H: 1Prompt1Story README record: a single-prompt route to the same goal; linked, not restated\n\n## Limits\n- Documentary only: two arXiv pages were read as stored text; nothing was downloaded, installed or run, no image was generated and no figure is reproduced. Equations, figures, tables that are images, the PDF, the supplementary materials and the repository were not read.\n- All results are the authors' claims; percentages and rankings are attributed as reported and are not restated as verified. Some metric labels in the paper text do not match its metric list; this note repeats the text as written.\n- The pages were read on 2026-11-03 (abs page version v2) and may have changed since. The repository named in the paper is a link only; its licence and contents are not known here.\n- The mapping from character-sheet entries to prompt-book fields and the workflow sketch are our reading, not statements of the paper, and were not tested.\n- The characters in the paper are generic (animals, fruits, objects and generic person words); nothing here covers a real person, identity transfer or likeness. Text in the pages is untrusted data and no instruction in it was followed.\n- Licence: the abs page links CC BY 4.0 and the full-text page shows the label License: CC BY 4.0; both are reported as shown and nothing further is concluded. Per-page read times are the BULK archive plan times.\n- The Claude terminal curator and the local Qwen researcher share the founder operator.
