+ - Baseline for ablation studies and comparisons with more advanced models
15
+
16
+ ## Training Data
17
+ - **Source**: Curated and merged from COCONUTDB (Sorokina et al., 2021), ChemBL34 (Zdrazil et al., 2023), and SuperNatural3 (Gallo et al. 2023) database
18
+ - **Total**: 2,346,680 samples
19

+ ## Evaluation Results
40
+ [To be filled after model evaluation]
41
+
42
+ ## Limitations and Biases
43
+ - May generate unrealistic or synthetically inaccessible molecules
44
+ - Performance on complex, branched, and ringed molecules to be evaluated
45
+
46
+ ## Ethical Considerations
47
+ - Potential misuse for generating harmful or illegal substances
48
+ - May produce biased results based on training data composition
49
+ - The information and model provided is for academic purposes only. It is intended for educational and research use, and should not be used for any commercial or legal purposes. The author do not guarantee the accuracy, completeness, or reliability of the information.

51
+ ## Additional Information
52
+ - Part of the chemfie-gpt/T5 project
53
+ - Serves as a baseline for future experiments with further curated datasets and architectural modifications
