T5-small is a large language model released by Google, released under the apache-2.0 license, with a claimed knowledge cutoff of 2019-10-23. Its weights, configuration, and tokenizer files have been cryptographically hashed and permanently attested on Ethereum (Sepolia) by Weight Registry.
Description
Casts every NLP task -- translation, summarization, classification, question-answering -- as text-to-text generation via one encoder-decoder architecture. The 'small' checkpoint is 60M parameters, the smallest of five sizes released up to 11B, all sharing the same C4 (Colossal Clean Crawled Corpus) pretraining recipe.

Weight Hashes
Combined commitment: a Merkle root over the weights, config, and tokenizer hashes together (not a raw weights-only hash) -- see this project's v2 on-chain schema.
