@dxo/train

Async CPU training loop with canonical safetensors checkpoints.

Trainer.fitIter / run yield epoch, batch, and checkpoint events. Checkpoint events contain the canonical state, encoded bytes, and format: 'safetensors'; callers decide where to persist the bytes.

for await (const event of trainer.fitIter()) {
  if (event.type === 'checkpoint') save(event.bytes);
}
