| # MarinFold exp75 checkpoints | |
| Final checkpoints from the MarinFold contacts-v1 1.5B tuning sweep tracked in | |
| [Open-Athena/MarinFold#75](https://github.com/Open-Athena/MarinFold/issues/75). | |
| Both checkpoint formats are retained: | |
| - `hf/` contains a `Qwen3ForCausalLM` Hugging Face safetensors export with the | |
| contacts-v1 tokenizer colocated with the weights. | |
| - `checkpoints/` contains the original Levanter OCDBT checkpoint for training | |
| restart or re-export. | |
