Notes

  • The checkpoint weights exclude the frozen target embedding weights; SpecForge loads them from the target model.
  • The checkpoint is intended to be loaded by SpecForge/EAGLE3-compatible code.
  • training_state.pt is included for provenance and training-state inspection.
  • No benchmark claim is made in this card.
