Jamba-v0.1 is a large language model released by AI21 Labs, released under the apache-2.0 license, with a claimed knowledge cutoff of 2024-03-28. Its weights, configuration, and tokenizer files have been cryptographically hashed and permanently attested on Ethereum (Sepolia) by Weight Registry.
Description
AI21 Labs' hybrid Transformer-Mamba architecture, combining attention layers with more compute-efficient state-space blocks.

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.
