for anyone wanting a glossary to explain the naming scheme here:

E4B = 4B effective parameters (using per-layer embeddings)

E2B = 2B (like above)

it = instruction tuned (rlhf and all that jazz)

assistant = Multi-token drafters (the new 2x speed up)

> assistant

naming still hard I see

I wonder if they hadn't decided to call it a drafter when they named the files and were using assistant internally? google being google...

Yes they should have stick with the naming convention.
