Methodology & findings

Study design

Experimental comparative performance study evaluating two custom GPT models (ScholarAI and SciSpace) across four temporal sessions (September 5, November 13-15, 2025).

Sample

N = 4, 2 groups

Primary method

Descriptive statistics including absolute frequencies and percentages to summarize distribution of valid articles, invalid DOIs, and hallucinated references across study sessions. Inter-rater agreement monitoring across evaluation axes. No inferential statistics reported.

Main result

The study found that both AI models demonstrated significant limitations in research assistance. "The results of our study clearly indicate that AI model outputs are not free from misinformation both in interpretation of research results as well as research article citations." Specifically, "Cronbach's alpha (if item deleted) was interpreted correctly in only one session by both AI models, ScholarAI (session four) more detailed explanation than SciSpace (session two)." Additionally, "AI misinformation and bias in literature search continuing to increase in each subsequent session in both AI models, available through advanced ChatGPT5 platform is an important finding of our study."

Author conclusions

"This study demonstrates that while specialized AI models assist in research workflows, they are not a substitute for human expertise. Both models repeatedly failed to properly interpret complex biostatistical diagnostic parameters, such as Cronbach's alpha if item deleted test outputs. The results of our study clearly indicate that AI model outputs are not free from misinformation both in interpretation of research results as well as research article citations. It is imperative that researchers critically review the AI model outputs and validate the inferences and citations generated themselves."

Risk of bias

Evaluator subjectivity in assessment despite standardization training; Selection bias: only two custom GPTs evaluated from research and analysis category; Temporal specificity: data collected in specific months with rapid AI model evolution; Opacity of underlying AI algorithms prevents reproducibility assessment; Small number of sessions (4 per model) limiting generalizability; Temporal specificity (September-November 2025) affecting reproducibility; Limited sample of only 2 AI models from same platform (ChatGPT); Potential evaluator familiarity bias despite inter-rater agreement monitoring; model outputs may vary with updates; Small sample size: Only 4 sessions per AI model; Lack of standardized evaluation framework: Rubrics were modified using CLEAR tool but no validated instrument for assessing AI model output

Limitations

The authors identified five key limitations: "1
Researchers are novice in use of GPT AI models
Evaluation of AI output was subjective
Opacity of the underlying AI algorithms and lack of reproducibility
Rapid model evolution and temporal specificity of data
Contextual and domain-specific limits to generalizability."

Open questions raised

The authors identify that "investigation of specific generative AI models as research assistants is limited except for ChatGPT." They also note that "it is essential that the robustness of output of these AI models is evaluated and reported in literature to guide students and novice researchers regarding the common pitfalls and limitations."
