Struct ModelCard 

pub struct ModelCard {
    pub id: &'static str,
    pub family: Family,
    pub source: WeightSource,
    pub file: &'static str,
    pub tokenizer: TokenizerSpec,
    pub specials: SpecialTokenLayout,
    pub metadata: ModelMetadata,
    pub approx_bytes_f32: u64,
    pub parity: ParityStatus,
    pub unsupported: Option<&'static str>,
}

Everything needed to identify, fetch, and load one model.

Fields

id: &'static str

Stable kebab-case identifier, unique across the registry.

family: Family

Architecture family.

source: WeightSource

Which repo and revision the weights live in, and their on-disk format.

file: &'static str

Path of the weight file within the repo.

tokenizer: TokenizerSpec

Where the tokenizer comes from.

specials: SpecialTokenLayout

How many special tokens the tokenizer wraps a sequence in.

metadata: ModelMetadata

Architecture dimensions.

For the non-embedding families these are the nearest analogue rather than a literal reading: d_model is the model’s hidden width and vocab_size its output alphabet.

approx_bytes_f32: u64

Rough in-memory footprint at F32, from the published parameter count.

Approximate on purpose — it exists to tier CI and to warn before a machine starts swapping, not to be exact. Load at F16 to roughly halve it; see LoadOptions::with_dtype.

parity: ParityStatus

Whether anything checks this model’s numerics.

unsupported: Option<&'static str>

Set when the model cannot currently be loaded, saying why.

Three ported models are in this state, each for a recorded reason. A row that carries this is present because the model is part of the public API, not because it works.

Implementations

impl ModelCard

pub const fn is_loadable(&self) -> bool

Whether this model can actually be loaded today.

pub const fn is_embedding_model(&self) -> bool

Whether this model consumes sequence and can implement PlmRunner.

A property of the card, not of its Family: ESM3 contains both a sequence model and a VQ-VAE structure encoder that takes backbone coordinates, so the family alone does not settle it.

pub const fn family_str(&self) -> &'static str

Lowercase family name, for matching against string-keyed tables.

Trait Implementations

impl Clone for ModelCard

fn clone(&self) -> ModelCard

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ModelCard

impl Debug for ModelCard

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

Formats the value using the given formatter.
