gguf:tensor

(gguf:tensor file name)

The packed float array loaded for the tensor name, or nil when it was not loaded -- :metadata-only, or an :only list that did not name it. An F32 tensor is read straight into the array in one transfer; F16 and BF16 arrive through rontolisp:widen-float-bits. The array's dimensions are the row-major ones gguf:tensor-info reports.
