Struct GenerationConfig 

pub struct GenerationConfig {
    pub max_new_tokens: usize,
    pub eos_token_id: Option<u32>,
}

Generation limits and stop conditions for generate.

Fields

max_new_tokens: usize

Hard cap on how many new tokens to produce, regardless of whether an end-of-sequence token is ever sampled. Prevents an unbounded loop when a model or prompt never naturally reaches its EOS token.

eos_token_id: Option<u32>

A token id that ends generation immediately when sampled — the sampled token itself is not appended to the output or passed to on_token, matching the usual convention that EOS is control metadata, not part of the visible completion. Typically tokenizer.ggml.eos_token_id from the model’s GGUF metadata.
