The front page quotes a 28.8 GB lookup table without saying where the number comes from. It is the model's second GGUF file: one per_layer_token_embd.weight tensor, 160 x 320,001,536 values at IQ4_NL.

Verified on the pack this branch serves: the shard is 28,800,138,432 bytes; the tensor's packed payload is 160 x 320,001,536 x 18/32 = 28,800,138,240 bytes, and the 192-byte difference is the GGUF header. Upstream documents the same shape in docs/UNSLOTH_Q6.md ("per_layer_token_embd.weight, [160, 320001536]") and the 28.8 GB figure in docs/HOW_IT_WORKS.md, docs/DETAILS.md, docs/MAC.md and docs/DGX_SPARK_LINUX.md.

The same text now notes that the figure is decimal GB (26.8 GiB in df) and that a pack storing the table in another type is larger - Q8_0 makes it 54.4 GB.

Documentation only; no source, flag or default changed.

The front page quotes a 28.8 GB lookup table without saying where the
number comes from. It is the model's second GGUF file: one
per_layer_token_embd.weight tensor, 160 x 320,001,536 values at IQ4_NL.

Verified on the pack this branch serves: the shard is 28,800,138,432
bytes, the tensor's packed payload is 160 x 320,001,536 x 18/32 =
28,800,138,240 bytes, and the 192 bytes left over are the GGUF header.
Upstream documents the same shape in docs/UNSLOTH_Q6.md and the 28.8 GB
figure in HOW_IT_WORKS.md, DETAILS.md, MAC.md and DGX_SPARK_LINUX.md.

The glossary entry now says what the number is, that it is decimal GB
(26.8 GiB in df), and that a pack storing the table in another type is
larger - Q8_0 makes the same table 54.4 GB.
