Enum Model 

pub enum Model {
    GPT41,
    GPT41Mini,
    GPT41Nano,
    GPT45,
    Other(String),
}

Represents the available AI models for commit message generation. Each model has different capabilities and token limits.

Known variants exist so we can specialize tokenizer/context-size handling for them, but any other model string is carried through verbatim via Other so users can point git-ai at arbitrary models (e.g. local ollama endpoints).

Variants

GPT41

GPT-4.1 - highest quality of the GPT-4.1 family

GPT41Mini

Mini version of GPT-4.1: faster/cheaper, the default for this per-commit tool

GPT41Nano

Nano version of GPT-4.1 for very fast processing

GPT45

GPT-4.5 model for advanced capabilities

Other(String)

Any other model string, carried through verbatim (e.g. local/ollama models).

Implementations

impl Model

pub fn count_tokens(&self, text: &str) -> Result<usize>

Counts the number of tokens in the given text for the current model. This is used to ensure we stay within the model’s token limits.

Arguments

• text - The text to count tokens for

Returns

• Result<usize> - The number of tokens or an error

pub fn context_size(&self) -> usize

Gets the maximum context size for the current model.

Returns

• usize - The maximum number of tokens the model can process

impl Model

pub fn as_str(&self) -> &str

Trait Implementations

impl AsRef<str> for Model

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

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 Default for Model

fn default() -> Model

Returns the “default value” for a type.

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 Eq for Model

impl From<&Model> for String

fn from(model: &Model) -> Self

Converts to this type from the input type.

impl From<&str> for Model

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for Model

fn from(s: String) -> Self

Converts to this type from the input type.

impl FromStr for Model

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

Parses a string s to return a value of this type.

impl Hash for Model

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
