Struct ContrastiveConfig 

pub struct ContrastiveConfig {
    pub k: usize,
    pub alpha: f32,
    pub max_len: usize,
}

Configuration for contrastive search decoding.

Fields

• k — top-k candidates to consider at each step (≥ 1).
• alpha — degeneration penalty weight ∈ [0, 1]. α = 0 reduces to greedy decoding; α = 1 ignores model probability entirely.
• max_len — maximum number of tokens to generate.

Fields

k: usize

Number of top-probability candidates to consider at each step.

alpha: f32

Degeneration penalty weight ∈ [0, 1].

max_len: usize

Maximum generation length (number of tokens produced).
