Implementations§

Source§

impl NeedleModel

Source

pub fn load(safetensors: &Path, device: &Device) -> Result<Self>

Load from the needle-1 bf16 safetensors (HF naming). Runs in f32 on CPU.

Source

pub fn encode(&self, enc_ids: &Tensor) -> Result<Tensor>

Encode enc_ids: [B,Te] → encoder states [B,Te,D] (no padding mask; assumes packed sequences).

Source

pub fn decode(&self, dec_ids: &Tensor, enc_out: &Tensor) -> Result<Tensor>

Decode dec_ids: [B,Td] against enc_out → logits [B,Td,VOCAB] (causal self-attn).

Source

pub fn forward(&self, enc_ids: &Tensor, dec_ids: &Tensor) -> Result<Tensor>

Full teacher-forced forward: (enc_ids, dec_ids) → logits [B,Td,VOCAB].

Source

pub fn device(&self) -> &Device
