juiceb0xc0de/AI21-Jamba2-3B A brain atlas for ai21labs/AI21-Jamba2-3B, a 28-layer hybrid Mamba/transformer from AI21 Labs. This is not a chat dataset or a benchmark. It is an internal-mechanics map built by running activations through a corpus of prompts and scoring what each layer, component, head, and direction is doing. Jamba is an interesting subject because it is mostly not attention. Of the 28 layers, only 2 carry attention, and both of those run a single KV head.… See the full description on the dataset page: https://huggingface.co/datasets/juiceb0xc0de/AI21-Jamba2-3B.
