Enum Model 

pub enum Model {
    Sonnet,
    Opus,
    Haiku,
    Haiku45,
    Sonnet46,
    Opus46,
    Sonnet46_1M,
    Opus46_1M,
}

Available Claude models.

Each variant maps to a model name passed to the Claude CLI. Use the alias variants (Sonnet, Opus, Haiku) for the latest version, or the explicit variants for a specific model ID and context window.

Variants

Sonnet

Claude Sonnet - balanced speed and capability (default, 200K context).

Opus

Claude Opus - highest capability (200K context).

Haiku

Claude Haiku - fastest and cheapest (200K context).

Haiku45

Claude Haiku 4.5 - 200K context.

Sonnet46

Claude Sonnet 4.6 - 200K context.

Opus46

Claude Opus 4.6 - 200K context.

Sonnet46_1M

Claude Sonnet 4.6 with 1M token context window.

Opus46_1M

Claude Opus 4.6 with 1M token context window.

Implementations

impl Model

pub fn context_window(self) -> usize

Maximum context window size in tokens.

Trait Implementations

impl Clone for Model

fn clone(&self) -> Model

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Model

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Model

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Model

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

Formats the value using the given formatter.

impl PartialEq for Model

fn eq(&self, other: &Model) -> 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.

impl Serialize for Model

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Model

impl Eq for Model

impl StructuralPartialEq for Model
