Pythia-160M is a large language model released by EleutherAI, released under the apache-2.0 license, with a claimed knowledge cutoff of 2023-02-13. Its weights, configuration, and tokenizer files have been cryptographically hashed and permanently attested on Ethereum (Sepolia) by Weight Registry.
Description
160M-parameter member of EleutherAI's Pythia suite -- 8 model sizes from 70M to 12B, each trained on the identical Pile dataset in the identical order, with 154 intermediate checkpoints saved per model -- built as a controlled experiment platform for interpretability and training-dynamics research.
