Struct ModelProfile 

#[non_exhaustive]
pub struct ModelProfile {
    pub context_window: Option<u64>,
    pub max_output_tokens: Option<u64>,
    pub reasoning_efforts: Vec<String>,
    pub thinking: bool,
    pub vision: bool,
}

What one model supports. Every field is optional knowledge: None means “not stated”, never “not supported”, so a partial catalog entry can still be useful.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

context_window: Option<u64>

Total context window in tokens, when known. A host renders budget and compaction decisions from this; core never enforces it.

max_output_tokens: Option<u64>

Ceiling on tokens the model will generate in one response.

reasoning_efforts: Vec<String>

Reasoning-effort values this model accepts, e.g. ["low", "high"]. Empty means the model takes no effort setting at all — which is what makes passing one an error rather than a no-op.

thinking: bool

Whether the model supports an extended-thinking token budget.

vision: bool

Whether the model accepts image content.

Implementations

impl ModelProfile

pub fn new() -> ModelProfile

A profile that states nothing. Build one up with the setters.

pub fn context_window(self, tokens: u64) -> ModelProfile

State the context window, in tokens.

pub fn max_output_tokens(self, tokens: u64) -> ModelProfile

State the per-response output ceiling, in tokens.

pub fn reasoning_efforts( self, efforts: impl IntoIterator<Item = impl Into<String>>, ) -> ModelProfile

State which reasoning-effort values the model accepts.

pub fn thinking(self, supported: bool) -> ModelProfile

State that the model supports an extended-thinking budget.

pub fn vision(self, supported: bool) -> ModelProfile

State that the model accepts images.

pub fn validate(&self, model: &ModelSpec) -> Result<(), String>

Why this model cannot serve model, if it cannot.

Checks only what the profile actually states — an empty profile accepts everything, so attaching a catalog can never reject a model it simply does not describe.
