When to use it

No task or capability claim is recorded beyond the card's Modality: Text row, because the card's only capability language sits in its Modality-Specific Post-Training section — it describes the ERNIE 4.5 LLMs as "optimized for general-purpose language understanding and generation" — and this repository's training stage is left unresolved: the Model Overview prose calls the model Post-trained while the configuration table's Training Stage row reads Pretraining, reconciled nowhere. Recording a post-training capability while the stage is unsettled would assert the contested side, so it is withheld rather than smoothed over. The -PT in the repository name is the card's own label for Transformer-style PyTorch weights rather than a training stage, and the vision-language members of the same generation are not recorded here.
