# B200 memory architecture checkpoints

This repository contains checkpoints from the
`streaming_3d_perception_online_memory` project.

| Architecture | Training step | Checkpoint | Configuration |
| --- | ---: | --- | --- |
| GDN-2 | 20,000 | `gdn2/checkpoint_000020000.pt` | `gdn2/config.yaml` |
| LaCT | 20,000 | `lact/checkpoint_000020000.pt` | `lact/config.yaml` |
| Mamba-3 | 20,000 | `mamba3/checkpoint_000020000.pt` | `mamba3/config.yaml` |
| Transformer | 13,000 | `transformer/checkpoint_000013000.pt` | `transformer/config.yaml` |

The runs used four B200 nodes with eight GPUs per node, for 32 B200 GPUs in
total. These are complete training checkpoints and may contain model,
optimizer, scheduler, and random-number-generator state.

See `SHA256SUMS` for checkpoint integrity hashes.
