Enum LmHeadFormat 

pub enum LmHeadFormat {
    Bf16,
    Fp8,
    Nvfp4,
}

2026-09-28: The lm_head format --lm-head-dtype default resolves to under declared.

Variants

Bf16

2026-09-28: The head stays 16-bit (the checkpoint does not quantize it).

Fp8

2026-09-28: The checkpoint’s FP8 head, decoded W8A16 (W8A8 once the kernels land).

Nvfp4

2026-09-28: NVFP4.

Trait Implementations

impl Clone for LmHeadFormat

fn clone(&self) -> LmHeadFormat

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LmHeadFormat

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for LmHeadFormat

fn eq(&self, other: &LmHeadFormat) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
