Architecture and scale

This model keeps the six-layer depth of Pythia 14M but increases the hidden width to 256. The non-embedding network has about 4.74 million parameters. Its architecture offers a width comparison without also doubling the number of layers.pythia-31m model cardpythia-31m model configuration

Weights and training revisions

This URL now contains a model trained on the standard Pile. Before the correction, it served the deduplicated model. Older experiments using the same unqualified name can therefore refer to different weights. The displaced model remains available under the deduped name.pythia-31m model card
