-#### Skipping CI Checks
-
-You can skip certain CI checks by including specific keywords in your commit messages:
-
-- `[skip ci]` or `skip ci` - Skips all CI checks for that commit
-- `[skip-e2e]` or `skip-e2e` - Skips only end-to-end tests while running other CI checks. You may also include this in the title of your PR to disable end-to-end tests for the entire PR.

-title: Streaming Datasets
-description: How to use streaming mode for large-scale datasets and memory-efficient training
-order: 10
----
-
-Streaming enables memory-efficient training with large datasets by loading data
-incrementally rather than loading the entire dataset into memory at once.
-
-Use streaming when:
-
-- Your dataset is too large to fit in memory (e.g. when you're doing pretraining with massive text corpora)
-- You want to start training immediately without preprocessing the entire dataset
-
-Streaming works with both remote and locally stored datasets!
-
-::: {.callout-note}
-Streaming currently only supports a single dataset. Multi-dataset support will be added soon.
-:::
-
-
-## Configuration
-
-### Basic Streaming
-
-Enable streaming mode by setting the `streaming` flag:
-
-```yaml
-streaming: true
-```
-
-### Pretraining with Streaming
-
-For pretraining tasks, streaming is automatically enabled when using `pretraining_dataset`:
-
-```yaml
-pretraining_dataset:
-  - path: HuggingFaceFW/fineweb-edu
-    type: pretrain
-    text_column: text
-    split: train
-
-# Optionally, enable sample packing
-streaming_multipack_buffer_size: 10000
-sample_packing: true
-```
-
-### SFT with Streaming
-
-For supervised fine-tuning with streaming:
-
-```yaml
-streaming: true
-datasets:
-  - path: tatsu-lab/alpaca
-    type: alpaca
-    split: train
-
-# Optionally, enable sample packing
-streaming_multipack_buffer_size: 10000
-sample_packing: true
-```
-
-## Configuration Options
-
-### `streaming_multipack_buffer_size`
-
-Controls the buffer size for multipack streaming (default: 10,000). This determines how
-many samples are buffered before packing. Larger buffers can improve packing efficiency
-but use more memory.
-
-### `shuffle_merged_datasets`
-
-When enabled, shuffles the streaming dataset using the buffer. This requires additional
-memory for the shuffle buffer.
-
-## Sample Packing with Streaming
-
-Sample packing is supported for streaming datasets. When enabled, multiple samples are
-packed into a single sequence to maximize GPU utilization:
-
-```yaml
-sample_packing: true
-streaming_multipack_buffer_size: 10000
-
-# For SFT: attention is automatically isolated between packed samples
-# For pretraining: control with pretrain_multipack_attn
-pretrain_multipack_attn: true  # prevent cross-attention between packed samples
-```
-
-For more information, see our [documentation](multipack.qmd) on multipacking.
-
-## Important Considerations
-
-### Memory Usage
-
-While streaming reduces memory usage compared to loading entire datasets, you still need
-to consider:
-
-- You can control the memory usage by adjusting `streaming_multipack_buffer_size`
-- Sample packing requires buffering multiple samples
-- Shuffling requires additional memory for the shuffle buffer
-
-### Performance
-
-- Streaming may have slightly higher latency compared to preprocessed datasets, as samples are processed on-the-fly
-- Network speed and disk read speed are important when streaming from remote sources or a local dataset, respectively
-- Consider using `axolotl preprocess` for smaller or more frequently used datasets
-
-### Evaluation Datasets
-
-Evaluation datasets are not streamed to ensure consistent evaluation metrics. They're
-loaded normally even when training uses streaming.
-
-## Examples
-
-See the `examples/streaming/` directory for complete configuration examples:
-
-- `pretrain.yaml`: Pretraining with streaming dataset
-- `sft.yaml`: Supervised fine-tuning with streaming

-# Finetune Liquid Foundation Models 2 (LFM2) with Axolotl
-
-[Liquid Foundation Models 2 (LFM2)](https://huggingface.co/collections/LiquidAI/lfm2-686d721927015b2ad73eaa38) are a family of small, open-weight models from [Liquid AI](https://www.liquid.ai/) focused on quality, speed, and memory efficiency. Liquid AI released text-only [LFM2](https://huggingface.co/collections/LiquidAI/lfm2-686d721927015b2ad73eaa38) and text+vision [LFM2-VL](https://huggingface.co/collections/LiquidAI/lfm2-vl-68963bbc84a610f7638d5ffa) models.
-
-LFM2 features a new hybrid Liquid architecture with multiplicative gates, short-range convolutions, and grouped query attention, enabling fast training and inference.
-
-This guide shows how to fine-tune both the LFM2 and LFM2-VL models with Axolotl.
-
-## Getting Started
-
-1.  Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html).
-
-    Here is an example of how to install from pip:
-    ```bash
-    # Ensure you have a compatible version of Pytorch installed
-    pip3 install packaging setuptools wheel ninja
-    pip3 install --no-build-isolation 'axolotl[flash-attn]>=0.12.0'
-    ```
-
-2.  Run one of the finetuning examples below.
-
-    **LFM2**
-    ```bash
-    # FFT SFT (1x48GB @ 25GiB)
-    axolotl train examples/LiquidAI/lfm2-350m-fft.yaml
-    ```
-
-    **LFM2-VL**
-    ```bash
-    # LoRA SFT (1x48GB @ 2.7GiB)
-    axolotl train examples/LiquidAI/lfm2-vl-lora.yaml
-    ```
-
-### TIPS
-
-- **Installation Error**: If you encounter `ImportError: ... undefined symbol ...` or `ModuleNotFoundError: No module named 'causal_conv1d_cuda'`, the `causal-conv1d` package may have been installed incorrectly. Try uninstalling it:
-  ```bash
-  pip uninstall -y causal-conv1d
-  ```
-
-- **Dataset Loading**: Read more on how to load your own dataset in our [documentation](https://docs.axolotl.ai/docs/dataset_loading.html).
-- **Dataset Formats**:
-  - For LFM2 models, the dataset format follows the OpenAI Messages format as seen [here](https://docs.axolotl.ai/docs/dataset-formats/conversation.html#chat_template).
-  - For LFM2-VL models, Axolotl follows the multi-content Messages format. See our [Multimodal docs](https://docs.axolotl.ai/docs/multimodal.html#dataset-format) for details.

-# Finetune ArceeAI's AFM with Axolotl
-
-[Arcee Foundation Models (AFM)](https://huggingface.co/collections/arcee-ai/afm-45b-68823397c351603014963473) are a family of 4.5B parameter open weight models trained by Arcee.ai.
-
-This guide shows how to fine-tune it with Axolotl with multi-turn conversations and proper masking.
-
-Thanks to the team at Arcee.ai for using Axolotl in supervised fine-tuning the AFM model.
-
-## Getting started
-
-1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html). You need to install from main as AFM is only on nightly or use our latest [Docker images](https://docs.axolotl.ai/docs/docker.html).
-
-    Here is an example of how to install from main for pip:
-
-```bash
-# Ensure you have Pytorch installed (Pytorch 2.6.0 min)
-git clone https://github.com/axolotl-ai-cloud/axolotl.git
-cd axolotl
-
-pip3 install packaging==23.2 setuptools==75.8.0 wheel ninja
-pip3 install --no-build-isolation -e '.[flash-attn]'
-```
-
-2. Run the finetuning example:
-
-```bash
-axolotl train examples/arcee/afm-4.5b-qlora.yaml
-```
-
-This config uses about 7.8GiB VRAM.
-
-Let us know how it goes. Happy finetuning! 🚀
-
-### TIPS
-
-- For inference, the official Arcee.ai team recommends `top_p: 0.95`, `temperature: 0.5`, `top_k: 50`, and `repeat_penalty: 1.1`.
-- You can run a full finetuning by removing the `adapter: qlora` and `load_in_4bit: true` from the config.
-- Read more on how to load your own dataset at [docs](https://docs.axolotl.ai/docs/dataset_loading.html).
-- The dataset format follows the OpenAI Messages format as seen [here](https://docs.axolotl.ai/docs/dataset-formats/conversation.html#chat_template).

-# ND Parallelism Examples
-
-This directory contains example configurations for training models using ND Parallelism in Axolotl. These examples demonstrate how to compose different parallelism strategies (FSDP, TP, CP, HSDP) for efficient multi-GPU training.
-
-## Quick Start
-
-1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html).
-
-2. Run the command below:
-
-```bash
-# Train Qwen3 8B with FSDP + TP + CP on a single 8-GPU node
-axolotl train examples/distributed-parallel/qwen3-8b-fsdp-tp-cp.yaml
-
-# Train Llama 3.1 8B with HSDP + TP on 2 nodes (16 GPUs total)
-axolotl train examples/distributed-parallel/llama-3_1-8b-hsdp-tp.yaml
-```
-
-## Example Configurations
-
-### Single Node (8 GPUs)
-
-**Qwen3 8B with FSDP + TP + CP** ([qwen3-8b-fsdp-tp-cp.yaml](./qwen3-8b-fsdp-tp-cp.yaml))
-- Uses all 3 parallelism dimensions on a single node
-- Ideal for: when model weights, activations, and/or context are too large to fit on single GPU
-
-```yaml
-dp_shard_size: 2         # FSDP across 2 GPUs
-tensor_parallel_size: 2  # TP across 2 GPUs
-context_parallel_size: 2 # CP across 2 GPUs
-# Total: 2 × 2 × 2 = 8 GPUs
-```
-
-### Multi-Node
-
-**Llama 3.1 8B with HSDP + TP** ([llama-3_1-8b-hsdp-tp.yaml](./llama-3_1-8b-hsdp-tp.yaml))
-- FSDP & TP within nodes, DDP across nodes to minimize inter-node communication
-- Ideal for: Scaling to multiple nodes while maintaining training efficiency
-
-```yaml
-dp_shard_size: 4        # FSDP within each 4-GPU group
-tensor_parallel_size: 2 # TP within each node
-dp_replicate_size: 2    # DDP across 2 groups
-# Total: (4 × 2) × 2 = 16 GPUs (2 nodes)
-```

-# Finetune OpenAI's GPT-OSS with Axolotl
-
-[GPT-OSS](https://huggingface.co/collections/openai/gpt-oss-68911959590a1634ba11c7a4) are a family of open-weight MoE models trained by OpenAI, released in August 2025. There are two variants: 20B and 120B.
-
-This guide shows how to fine-tune it with Axolotl with multi-turn conversations and proper masking.
-
-## Getting started
-
-1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html).
-
-    Here is an example of how to install from pip:
-
-```bash
-# Ensure you have Pytorch installed (Pytorch 2.6.0 min)
-pip3 install packaging==23.2 setuptools==75.8.0 wheel ninja
-pip3 install --no-build-isolation 'axolotl[flash-attn]>=0.12.0'
-```
-
-2. Choose one of the following configs below for training the 20B model. (for 120B, see [below](#training-120b))
-
-```bash
-# LoRA SFT linear layers (1x48GB @ ~44GiB)
-axolotl train examples/gpt-oss/gpt-oss-20b-sft-lora-singlegpu.yaml
-
-# FFT SFT with offloading (2x24GB @ ~21GiB/GPU)
-axolotl train examples/gpt-oss/gpt-oss-20b-fft-fsdp2-offload.yaml
-
-# FFT SFT (8x48GB @ ~36GiB/GPU or 4x80GB @ ~46GiB/GPU)
-axolotl train examples/gpt-oss/gpt-oss-20b-fft-fsdp2.yaml
-```
-
-Note: Memory usage taken from `device_mem_reserved(gib)` from logs.
-
-### Training 120B
-
-On 8xH100s, make sure you have ~3TB of free disk space. With each checkpoint clocking in at ~720GB, along with the base
-model, and final model output, you may need at least 3TB of free disk space to keep at least 2 checkpoints.
-
-```bash
-# FFT SFT with offloading (8x80GB @ ~49GiB/GPU)
-axolotl train examples/gpt-oss/gpt-oss-120b-fft-fsdp2-offload.yaml
-```
-
-To simplify fine-tuning across 2 nodes × 8x H100 (80GB) GPUs, we've partnered with [Baseten](https://baseten.co) to showcase multi-node
-training of the 120B model using Baseten Truss. You can read more about this recipe on
-[Baseten's blog](https://www.baseten.co/blog/how-to-fine-tune-gpt-oss-120b-with-baseten-and-axolotl/). The recipe can
-be found on their
-[GitHub](https://github.com/basetenlabs/ml-cookbook/tree/main/examples/oss-gpt-120b-axolotl/training).
-
-ERRATA: Transformers saves the model Architecture prefixed with `FSDP` which needs to be manually renamed in `config.json`.
-See https://github.com/huggingface/transformers/pull/40207 for the status of this issue.
-
-```bash
-sed -i 's/FSDPGptOssForCausalLM/GptOssForCausalLM/g' ./outputs/gpt-oss-out/config.json
-```
-
-When using SHARDED_STATE_DICT with FSDP, the final checkpoint should automatically merge the sharded weights to your
-configured `output_dir`. However, if that step fails due to a disk space error, you can take an additional step to
-merge the sharded weights.  This step will automatically determine the last checkpoint directory and merge the sharded
-weights to `{output_dir}/merged`.
-
-```bash
-axolotl merge-sharded-fsdp-weights examples/gpt-oss/gpt-oss-120b-fft-fsdp2-offload.yaml
-mv ./outputs/gpt-oss-out/merged/* ./outputs/gpt-oss-out/
-```
-
-
-### Inferencing your fine-tuned model
-
-#### vLLM
-
-GPT-OSS support in vLLM does not exist in a stable release yet. See https://x.com/MaziyarPanahi/status/1955741905515323425
-for more information about using a special vllm-openai docker image for inferencing with vLLM.
-
-Optionally, vLLM can be installed from nightly:
-
-```bash
-pip install --no-build-isolation --pre -U vllm --extra-index-url https://wheels.vllm.ai/nightly
-```
-and the vLLM server can be started with the following command (modify `--tensor-parallel-size 8` to match your environment):
-```bash
-vllm serve ./outputs/gpt-oss-out/ --served-model-name axolotl/gpt-oss-20b --host 0.0.0.0 --port 8888  --tensor-parallel-size 8
-```
-
-#### SGLang
-
-SGLang has 0-day support in main, see https://github.com/sgl-project/sglang/issues/8833 for infomation on installing
-SGLang from source. Once you've installed SGLang, run the following command to launch a SGLang server:
-
-```bash
-python3 -m sglang.launch_server --model ./outputs/gpt-oss-out/ --served-model-name axolotl/gpt-oss-120b --host 0.0.0.0 --port 8888 --tp 8
-```
-
-### Tool use
-
-GPT-OSS has a comprehensive tool understanding. Axolotl supports tool calling datasets for Supervised Fine-tuning.
-
-Here is an example dataset config:
-```yaml
-datasets:
-  - path: Nanobit/text-tools-2k-test
-    type: chat_template
-```
-
-See [Nanobit/text-tools-2k-test](https://huggingface.co/datasets/Nanobit/text-tools-2k-test) for the sample dataset.
-
-Refer to [our docs](https://docs.axolotl.ai/docs/dataset-formats/conversation.html#using-tool-use) for more info.
-
-### Thinking and chat_template masking conflict
-
-OpenAI’s Harmony template hides `thinking` in all non-final turns, which conflicts with Axolotl’s `chat_template` masking.
-
-If your dataset has `thinking` content mid-turn, there are two paths we recommend:
-
-- Train only on the last turn. This can be accomplished via chat_template's [train on last doc](https://docs.axolotl.ai/docs/dataset-formats/conversation.html#training-on-last-message).
-
-- Adjust your dataset to only have `thinking` content in the last turn.
-
-### TIPS
-
-- Read more on how to load your own dataset at [docs](https://docs.axolotl.ai/docs/dataset_loading.html).
-- The dataset format follows the OpenAI Messages format as seen [here](https://docs.axolotl.ai/docs/dataset-formats/conversation.html#chat_template).

-# Finetune HunYuan with Axolotl
-
-Tencent released a family of opensource models called HunYuan with varying parameter scales of 0.5B, 1.8B, 4B, and 7B scale for both Pre-trained and Instruct variants. The models can be found at [HuggingFace](https://huggingface.co/collections/tencent/hunyuan-dense-model-6890632cda26b19119c9c5e7). This guide shows how to fine-tune it with Axolotl with multi-turn conversations and proper masking.
-
-## Getting started
-
-1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html). You need to install from main as HunYuan is only on nightly or use our latest [Docker images](https://docs.axolotl.ai/docs/docker.html).
-
-    Here is an example of how to install from main for pip:
-
-```bash
-# Ensure you have Pytorch installed (Pytorch 2.6.0 min)
-git clone https://github.com/axolotl-ai-cloud/axolotl.git
-cd axolotl
-
-pip3 install packaging==23.2 setuptools==75.8.0 wheel ninja
-pip3 install --no-build-isolation -e '.[flash-attn]'
-
-# Install CCE https://docs.axolotl.ai/docs/custom_integrations.html#cut-cross-entropy
-python scripts/cutcrossentropy_install.py | sh
-```
-
-2. Run the finetuning example:
-
-```bash
-axolotl train examples/hunyuan/hunyuan-v1-dense-qlora.yaml
-```
-
-This config uses about 4.7 GB VRAM.
-
-Let us know how it goes. Happy finetuning! 🚀
-
-### Dataset
-
-HunYuan Instruct models can choose to enter a slow think or fast think pattern. For best performance on fine-tuning their Instruct models, your dataset should be adjusted to match their pattern.
-
-```python
-# fast think pattern
-messages = [
-    {"role": "system", "content": "You are a helpful assistant."},
-    {"role": "user", "content": "/no_think What color is the sun?" },
-    {"role": "assistant", "content": "<think>\n\n</think>\n<answer>\nThe sun is yellow.\n</answer>"}
-]
-
-# slow think pattern
-messages = [
-    {"role": "system", "content": "You are a helpful assistant."},
-    {"role": "user", "content": "/no_think What color is the sun?" },
-    {"role": "assistant", "content": "<think>\nThe user is asking about the color of the sun. I need to ...\n</think>\n<answer>\nThe sun is yellow.\n</answer>"}
-]
-```

-# SLURM Multi-Node Training
-
-This directory contains an example SLURM script for running Axolotl training jobs across multiple nodes in a SLURM cluster.
-
-## Prerequisites
-
-- Access to a SLURM cluster with GPU nodes
-- Axolotl installed on all nodes (see [installation docs](https://docs.axolotl.ai/docs/installation.html))
-
-## Usage
-
-### Standard SLURM Clusters
-
-1. Copy [`axolotl.slurm`](./axolotl.slurm) to your working directory.
-2. Place your Axolotl config file (`train.yaml`) in the same directory.
-3. Set the appropriate environment variables for the job:
-    ```bash
-    export HF_TOKEN="your-huggingface-token"
-
-    # metric tracking
-    # export WANDB_API_KEY="your-wandb-api-key"
-    # ...
-    ```
-4. Submit the job:
-   ```bash
-   sbatch --export=ALL,NUM_NODES=2,NUM_TRAINERS=8,PRIMARY_ADDR=<master-node>,PRIMARY_PORT=29400 axolotl.slurm
-   ```
-
-   Where:
-   - `NUM_NODES`: Number of nodes to use
-   - `NUM_TRAINERS`: GPUs per node (typically 8)
-   - `PRIMARY_ADDR`: Hostname/IP of the master node
-   - `PRIMARY_PORT`: Port for distributed training (default: 29400)
-
-5. (Optional) Run other slurm commands:
-    ```bash
-    # check job info
-    scontrol show job axolotl-cli
-
-    # check job queue
-    squeue
-
-    # check cluster status
-    sinfo
-    ```
-
-### RunPod Instant Clusters
-
-Axolotl works with RunPod Instant Clusters. This feature provides managed SLURM clusters with zero configuration.
-
-1. **Deploy a SLURM Cluster**:
-   - Go to [RunPod Instant Clusters](https://console.runpod.io/cluster)
-   - Click "Create a Cluster"
-   - Choose your GPU type, node count, and region
-   - Choose an [Axolotl cloud docker image](https://docs.axolotl.ai/docs/docker.html#cloud)
-   - Deploy the cluster
-
-2. **Connect to the Controller Node**: Find the controller node in the RunPod console and connect via SSH
-
-3. **Follow the instructions in [Standard SLURM Clusters](#standard-slurm-clusters)**

-# Finetune SmolVLM2 with Axolotl
-
-[SmolVLM2](https://huggingface.co/collections/HuggingFaceTB/smolvlm2-smallest-video-lm-ever-67ab6b5e84bf8aaa60cb17c7) are a family of lightweight, open-source multimodal models from HuggingFace designed to analyze and understand video, image, and text content.
-
-These models are built for efficiency, making them well-suited for on-device applications where computational resources are limited. Models are available in multiple sizes, including 2.2B, 500M, and 256M.
-
-This guide shows how to fine-tune SmolVLM2 models with Axolotl.
-
-## Getting Started
-
-1.  Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html).
-
-    Here is an example of how to install from pip:
-    ```bash
-    # Ensure you have a compatible version of Pytorch installed
-    pip3 install packaging setuptools wheel ninja
-    pip3 install --no-build-isolation 'axolotl[flash-attn]>=0.12.0'
-    ```
-
-2. Install an extra dependency:
-
-    ```bash
-    pip3 install num2words==0.5.14
-    ```
-
-3.  Run the finetuning example:
-
-    ```bash
-    # LoRA SFT (1x48GB @ 6.8GiB)
-    axolotl train examples/smolvlm2/smolvlm2-2B-lora.yaml
-    ```
-
-## TIPS
-
-- **Dataset Format**: For video finetuning, your dataset must be compatible with the multi-content Messages format. For more details, see our documentation on [Multimodal Formats](https://docs.axolotl.ai/docs/multimodal.html#dataset-format).
-- **Dataset Loading**: Read more on how to prepare and load your own datasets in our [documentation](https://docs.axolotl.ai/docs/dataset_loading.html).

-# Streaming Dataset Examples
-
-This directory contains example configurations for using Axolotl's streaming dataset
-functionality, which enables memory-efficient training with large datasets.
-
-## Examples
-
-Run the following examples with e.g. `axolotl train examples/streaming/sft.yaml`; no
-`axolotl preprocess` required!
-
-### Pretraining (`pretrain.yaml`)
-
-Demonstrates streaming configuration for pretraining tasks using the fineweb-edu dataset
-with SmolLM2-135M.
-
-- Uses `pretraining_dataset` configuration for automatic streaming
-- Multipack attention control to prevent cross-attention between packed sequences
-- Buffer size configuration for memory management
-
-### SFT (`sft.yaml`)
-
-Shows how to use streaming for supervised fine-tuning with the Alpaca dataset.
-
-- Explicit `streaming: true` flag for SFT datasets
-- Memory-efficient training on instruction datasets
-- Evaluation datasets are currently not streamed
-
-## Key Configuration Options
-
-### `streaming`
-- Enables streaming mode for standard datasets
-- Automatically enabled for `pretraining_dataset`
-
-### `streaming_multipack_buffer_size`
-- Controls buffer size for sample packing (default: 10,000)
-- Larger values improve packing efficiency but use more memory
-- Adjust based on available memory
-
-### `shuffle_merged_datasets`
-- Enables shuffling of streaming datasets
-- Requires additional memory for shuffle buffer
-
-### `sample_packing`
-- Packs multiple samples into single sequences
-- Minimize per-step padding tokens
-
-## Performance Tips
-
-- Download small / frequently-used datasets locally for better performance
-- Larger buffer sizes improve packing efficiency
