Abstract

Recent artificial intelligence (AI) tools have demonstrated the ability to produce outputs traditionally considered creative. One such system is text-to-image generative AI (e.g. Midjourney, Stable Diffusion, DALL-E), which automates humans’ artistic execution to generate digital artworks. Utilizing a dataset of over 4 million artworks from more than 50,000 unique users, our research shows that over time, text-to-image AI significantly enhances human creative productivity by 25% and increases the value as measured by the likelihood of receiving a favorite per view by 50%. While peak artwork Content Novelty, defined as focal subject matter and relations, increases over time, average Content Novelty declines, suggesting an expanding but inefficient idea space. Additionally, there is a consistent reduction in both peak and average Visual Novelty, captured by pixel-level stylistic elements. Importantly, AI-assisted artists who can successfully explore more novel ideas, regardless of their prior originality, may produce artworks that their peers evaluate more favorably. Lastly, AI adoption decreased value capture (favorites earned) concentration among adopters. The results suggest that ideation and filtering are likely necessary skills in the text-to-image process, thus giving rise to “generative synesthesia”—the harmonious blending of human exploration and AI exploitation to discover new creative workflows.

TL;DR

Using over 4 million artworks from more than 50,000 users on an art-sharing platform, this paper finds that adopting text-to-image generative AI increases creative productivity and peer-evaluated value while average content and visual novelty decline and peak content novelty rises. It argues that human ideation and filtering—“generative synesthesia”—are key to benefiting from AI-assisted art.

Key findings

  • Adoption increased creative productivity: the abstract reports a 25% increase, while the Results report a 50% increase in the adoption month that doubles the following month, translating to about 7 additional artifacts in the adoption month and 15 in the following month for the average user.
  • Artwork value, measured as favorites per view after 2 weeks, rose 50% by the sixth month, from a preadoption average of 2% to a steady 3% rate of earning a favorite per view; the initial upward trend was nonsignificant, with significant differences from nonadopters after 3 months.
  • Average Content Novelty declined over time among adopters, but maximum Content Novelty increased and was marginally statistically significant within the first several months; both average and maximum Visual Novelty declined.
  • Artists who successfully explored more novel ideas, regardless of prior originality, may produce artworks peers evaluate more favorably; Content Novelty was more predictive of value gains than Visual Novelty. AI adoption was associated with less concentrated favorites: treated Gini 0.794 vs never-treated 0.807 (D = −0.0128, p = 0.0673) and not-yet-treated 0.824 (D = −0.0298, p = 0.0026).

Methods

  • Design: event-study difference-in-differences to estimate causal impact of AI adoption on productivity, value, and novelty; two-way fixed effects for heterogeneity by prior novelty quartiles; generalized random forests with SHAP for feature importance; Gini coefficients and permutation tests with 10,000 iterations for platform-level value concentration; generalized synthetic control method and falsification tests for robustness.
  • Data: over 4 million artworks from more than 50,000 unique users; over 53,000 artists and 5,800 known AI adopters; novelty analysis uses adopters and a random sample of 10,000 control users.
  • Novelty measurement: Content Novelty via BLIP-2 image captions plus BERT embeddings; Visual Novelty via DINOv2 embeddings; pairwise cosine distance to prior baseline artworks, with the baseline updated monthly.

Limitations

  • Stated: the authors do not directly observe users’ creative process, so the BVSR/generative synesthesia discussion is speculative; selection into AI adoption is a concern, addressed with generalized synthetic control and falsification tests.
  • Evident: AI adoption is identified by rule-based keyword/tag matching and AI art community labels, which may misclassify users or artworks; novelty and value are platform-specific proxies (embeddings and favorites per view after 2 weeks).
  • Evident: causal estimates rely on difference-in-differences assumptions, though robustness checks are reported; the sample comes from one art-sharing platform, limiting generalizability.

  • Broader concerns exist about AI-generated media and the risk of fabricating emotion or persona.

    “This resonates with broader concerns about AI-generated media and the risk of fabricating emotion or persona [18,81].”

    From Exploring the Collaborative Co-Creation Process with AI: A Case Study in Novice Music Production (2025) · cites this paper as [81]

    The Introduction describes concerns about AI-generated art, including its originality and its potential to replace human creativity. The Discussion also mentions disinformation as a potential risk. Neither section addresses fabricating emotion or persona, so the source supports the broader concern but not the specific risk named here. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
