-## Fine-tuning
-
-To fine-tune an OLMo model using our trainer you'll first need to prepare your dataset by tokenizing it and saving the tokens IDs to a flat numpy memory-mapped array. See [`scripts/prepare_tulu_data.py`](./scripts/prepare_tulu_data.py) for an example with the Tulu V2 dataset, which can be easily modified for other datasets.
-
-Next, prepare your training config. There are many examples in the [`configs/`](./configs) directory that you can use as a starting point. The most important thing is to make sure the model parameters (the `model` field in the config) match up with the checkpoint you're starting from. To be safe you can always start from the config that comes with the model checkpoint. At a minimum you'll need to make the following changes to the config or provide the corresponding overrides from the command line:
-
-- Update `load_path` to point to the checkpoint you want to start from.
-- Set `reset_trainer_state` to `true`.
-- Update `data.paths` to point to the `token_ids.npy` file you generated.
-- Optionally update `data.label_mask_paths` to point to the `label_mask.npy` file you generated, unless you don't need special masking for the loss.
-- Update `evaluators` to add/remove in-loop evaluations.
-
-Once you're satisfied with your training config, you can launch the training job via `torchrun`. For example:
-
-```
-torchrun --nproc_per_node=8 scripts/train.py {path_to_train_config} \
-    --data.paths=[{path_to_data}/input_ids.npy] \
-    --data.label_mask_paths=[{path_to_data}/label_mask.npy] \
-    --load_path={path_to_checkpoint} \
-    --reset_trainer_state
-```
-
-Note: passing CLI overrides like `--reset_trainer_state` is only necessary if you didn't update those fields in your config.

 The quantized model is more sensitive to typing / cuda, so it is recommended to pass the inputs as inputs.input_ids.to('cuda') to avoid potential issues.
 
+## Reproducibility
+
+### Training
+
+The configs used to train the official OLMo models are provided in the [`configs/official/`](https://github.com/allenai/OLMo/blob/main/configs/official) directory.
+
+Note that while the training and validation data is public and free to download, the paths to the data within those configs are pointed at a CloudFlare R2 bucket, which requires an API key for programmatic access.
+So in order to use any of these configs to reproduce a training run you'll first have to download the corresponding data to a location of your choosing and then update the paths in the config accordingly.
+
+You can derive the public HTTP URL from an R2 URL by replacing `r2://olmo-data` with `https://olmo-data.org`.
+For example, if the R2 data URL is:
+
+`r2://olmo-data/preprocessed/olmo-mix/v1_5/gpt-neox-20b-pii-special/part-000-00000.npy`
+
+then the corresponding public URL is:
+
+`https://olmo-data.org/preprocessed/olmo-mix/v1_5/gpt-neox-20b-pii-special/part-000-00000.npy`
+
+Once you've updated the data paths in the config you can launch a training run via `torchrun`. For example, to launch the 1B model training on a single 8x GPU node, you would run:
+
+```bash
+torchrun --nproc_per_node=8 scripts/train.py configs/official/OLMo-1B.yaml
+```
+
+You can use the same method to launch multi-node jobs as well. See [the documentation](https://pytorch.org/docs/stable/elastic/run.html) for `torchrun` to understand the additional arguments you'll need to configure the rendezvous backend / endpoint.
+
+### Inspecting training data
+
+You may be interesting in inspecting the exact tokens that composed a particular batch during the training of one of the OLMo models.
+We provide tools to do this, but first you'll need to download the data as above (unless you have an R2 API key) and update the corresponding config accordingly.
+
+Then take note of the URL of the data order file you want, which can be found in the [Models Overview](#models-overview) table. For example, the data order file for the first epoch of the OLMo-7B model is [https://olmo-checkpoints.org/ai2-llm/olmo-medium/wvc30anm/train_data/global_indices.npy](https://olmo-checkpoints.org/ai2-llm/olmo-small/46zc5fly/train_data/global_indices.npy).
+
+Once you have that you can use this snippet to inspect the data within a particular batch:
+
+```python
+import numpy as np
+from cached_path import cached_path
+
+from olmo.config import TrainConfig
+from olmo.data import build_memmap_dataset
+
+# Update these paths to what you want:
+data_order_file_path = cached_path("https://olmo-checkpoints.org/ai2-llm/olmo-medium/wvc30anm/train_data/global_indices.npy")
+train_config_path = "configs/official/OLMo-7B.yaml"
+
+
+cfg = TrainConfig.load(train_config_path)
+dataset = build_memmap_dataset(cfg, cfg.data)
+batch_size = cfg.global_train_batch_size
+global_indices = np.memmap(data_order_file_path, mode="r+", dtype=np.uint32)
+
+
+def get_batch_instances(batch_idx: int) -> list[list[int]]:
+    batch_start = batch_idx * batch_size
+    batch_end = (batch_idx + 1) * batch_size
+    batch_indices = global_indices[batch_start:batch_end]
+    batch_instances = []
+    for index in batch_indices:
+        token_ids = dataset[index]["input_ids"].tolist()
+        batch_instances.append(token_ids)
+    return batch_instances
+
+
+# Get all 2048 x 2048 token IDs in the first batch.
+get_batch_instances(0)
+```
