# LLM Foundry This repository contains code for training, finetuning, evaluating, and deploying LLMs for inference with [Composer](https://github.com/mosaicml/composer) and the [MosaicML platform](https://forms.mosaicml.com/demo?utm_source=github.com&utm_medium=referral&utm_campaign=llm-foundry). Designed to be easy-to-use, efficient _and_ flexible, this codebase enables rapid experimentation with the latest techniques. You'll find in this repo: * `llmfoundry/` - source code for models, datasets, callbacks, utilities, etc. * `scripts/` - scripts to run LLM workloads * `data_prep/` - convert text data from original sources to StreamingDataset format * `train/` - train or finetune HuggingFace and MPT models from 125M - 70B parameters * `train/benchmarking` - profile training throughput and MFU * `inference/` - convert models to HuggingFace or ONNX format, and generate responses * `inference/benchmarking` - profile inference latency and throughput * `eval/` - evaluate LLMs on academic (or custom) in-context-learning tasks * `mcli/` - launch any of these workloads using [MCLI](https://docs.mosaicml.com/projects/mcli/en/latest/) and the [MosaicML platform](https://www.mosaicml.com/platform) * `TUTORIAL.md` - a deeper dive into the repo, example workflows, and FAQs # DBRX DBRX is a state-of-the-art open source LLM trained by Databricks Mosaic team. It uses the Mixture-of-Experts (MoE) architecture and was trained with optimized versions of [Composer](https://github.com/mosaicml/composer), LLM Foundry, and [MegaBlocks](https://github.com/databricks/megablocks). The model has 132B total parameters and 36B active parameters. We have released two DBRX models: | Model | Context Length | Download | | ------------------ | -------------- | -------------------------------------------------- | | DBRX Base | 32768 | https://huggingface.co/databricks/dbrx-base | | DBRX Instruct | 32768 | https://huggingface.co/databricks/dbrx-instruct | Our model weights and code are licensed for both researchers and commercial entities.

This codebase may also work on systems with other devices, such as consumer NVIDIA cards and AMD cards, but we are not actively testing these systems. If you have success/failure using LLM Foundry on other systems, please let us know in a Github issue and we will update the support matrix! | Device | Torch Version | Cuda Version | Status | | -------------- | ------------- | ------------ | ---------------------------- | | A100-40GB/80GB | 2.3.1 | 12.1 | :white_check_mark: Supported | | H100-80GB | 2.3.1 | 12.1 | :white_check_mark: Supported | ## MosaicML Docker Images We highly recommend using our prebuilt Docker images. You can find them here: https://hub.docker.com/orgs/mosaicml/repositories. The `mosaicml/pytorch` images are pinned to specific PyTorch and CUDA versions, and are stable and rarely updated. The `mosaicml/llm-foundry` images are built with new tags upon every commit to the `main` branch. You can select a specific commit hash such as `mosaicml/llm-foundry:2.3.1_cu121-36ab1ba` or take the latest one using `mosaicml/llm-foundry:2.3.1_cu121-latest`. **Please Note:** The `mosaicml/llm-foundry` images do not come with the `llm-foundry` package preinstalled, just the dependencies. You will still need to `pip install llm-foundry` either from PyPi or from source. | Docker Image | Torch Version | Cuda Version | LLM Foundry dependencies installed? | | ------------------------------------------------------ | ------------- | ----------------- | ----------------------------------- | | `mosaicml/pytorch:2.3.1_cu121-python3.11-ubuntu20.04` | 2.3.1 | 12.1 (Infiniband) | No | | `mosaicml/llm-foundry:2.3.1_cu121-latest` | 2.3.1 | 12.1 (Infiniband) | Yes | | `mosaicml/llm-foundry:2.3.1_cu121_aws-latest` | 2.3.1 | 12.1 (EFA) | Yes | # Installation This assumes you already have PyTorch, CMake, and packaging installed. If not, you can install them with `pip install cmake packaging torch`. To get started, clone the repo and set up your environment. Instructions to do so differ slightly depending on whether you're using Docker. ### With Docker (recommended) We *strongly* recommend working with LLM Foundry inside a Docker container (see our recommended Docker image above). If you are doing so, follow these steps to clone the repo and install the requirements. ```bash git clone https://github.com/mosaicml/llm-foundry.git cd llm-foundry pip install -e ".[gpu]" # or `pip install -e .` if no NVIDIA GPU. ``` ### Without Docker (not recommended) If you choose not to use Docker, you should create and use a virtual environment. ```bash git clone https://github.com/mosaicml/llm-foundry.git cd llm-foundry # Creating and activate a virtual environment python3 -m venv llmfoundry-venv source llmfoundry-venv/bin/activate pip install cmake packaging torch # setup.py requires these be installed pip install -e ".[gpu]" # or `pip install -e .` if no NVIDIA GPU. ``` ### TransformerEngine and amp_fp8 support NVIDIA H100 GPUs have FP8 support; we have installed Flash Attention and Transformer in our Docker images already (see above). If you are not using our Docker images, you can install these packages with: ```bash pip install flash-attn --no-build-isolation pip install git+https://github.com/NVIDIA/TransformerEngine.git@stable ``` See [here](https://github.com/mosaicml/llm-foundry/blob/main/TUTORIAL.md#TransformerEngine-and-amp_fp8-support) for more details on enabling TransformerEngine layers and amp_fp8. ### AMD (BETA support) In [our testing of AMD GPUs](https://www.mosaicml.com/blog/amd-mi250), the env setup includes: ```bash git clone https://github.com/mosaicml/llm-foundry.git cd llm-foundry # Creating and activate a virtual environment python3 -m venv llmfoundry-venv-amd source llmfoundry-venv-amd/bin/activate # installs pip install cmake packaging torch pip install -e . # This installs some things that are not needed but they don't hurt pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/rocm5.4.2 ``` **Lastly**, install the ROCm enabled flash attention (instructions [here](https://github.com/ROCmSoftwarePlatform/flash-attention/tree/flash_attention_for_rocm2#amd-gpurocm-support)). Notes: 1. We don't yet have a Docker image where everything works perfectly. You might need to up/downgrade some packages (in our case, we needed to downgrade to `numpy==1.23.5`) before everything works without issue. ### Intel Gaudi Support for LLM Foundry on Intel Gaudi devices is experimental, please use the branch `habana_alpha` and see the [README on that branch](https://github.com/mosaicml/llm-foundry/blob/habana_alpha) which has [install instructions and known issues.](https://github.com/mosaicml/llm-foundry/tree/habana_alpha?tab=readme-ov-file#intel-gaudi) For training and inference performance results on Intel Gaudi2 accelerators, see our blog: https://www.databricks.com/blog/llm-training-and-inference-intel-gaudi2-ai-accelerators # Quickstart > **Note** > Make sure to go through the installation steps above before trying the quickstart! Here is an end-to-end workflow for preparing a subset of the C4 dataset, training an MPT-125M model for 10 batches, converting the model to HuggingFace format, evaluating the model on the Winograd challenge, and generating responses to prompts. **(Remember this is a quickstart just to demonstrate the tools -- To get good quality, the LLM must be trained for longer than 10 batches 😄)** ```bash cd scripts # Convert C4 dataset to StreamingDataset format python data_prep/convert_dataset_hf.py \ --dataset c4 --data_subset en \ --out_root my-copy-c4 --splits train_small val_small \ --concat_tokens 2048 --tokenizer EleutherAI/gpt-neox-20b --eos_text '<|endoftext|>' # Train an MPT-125m model for 10 batches composer train/train.py \ train/yamls/pretrain/mpt-125m.yaml \ variables.data_local=my-copy-c4 \ train_loader.dataset.split=train_small \ eval_loader.dataset.split=val_small \ max_duration=10ba \ eval_interval=0 \ save_folder=mpt-125m # Convert the model to HuggingFace format python inference/convert_composer_to_hf.py \ --composer_path mpt-125m/ep0-ba10-rank0.pt \ --hf_output_path mpt-125m-hf \ --output_precision bf16 \ # --hf_repo_for_upload user-org/repo-name # Evaluate the model on a subset of tasks composer eval/eval.py \ eval/yamls/hf_eval.yaml \ icl_tasks=eval/yamls/copa.yaml \ model_name_or_path=mpt-125m-hf # Generate responses to prompts python inference/hf_generate.py \ --name_or_path mpt-125m-hf \ --max_new_tokens 256 \ --prompts \ "The answer to life, the universe, and happiness is" \ "Here's a quick recipe for baking chocolate chip cookies: Start by" ``` Note: the `composer` command used above to train the model refers to the [Composer](https://github.com/mosaicml/composer) library's distributed launcher. If you have a write-enabled [HuggingFace auth token](https://huggingface.co/docs/hub/security-tokens), you can optionally upload your model to the Hub! Just export your token like this: ```bash export HF_TOKEN=your-auth-token ``` and uncomment the line containing `--hf_repo_for_upload ...` in the above call to `inference/convert_composer_to_hf.py`. # Registry You can use the registry to customize your workflows without forking the library. Some components of LLM Foundry are registrable, such as models, loggers, and callbacks. This means that you can register new options for these components, and then use them in your yaml config. ## Discovering registrable components To help find and understand registrable components, you can use the `llmfoundry registry` cli command. We provide two commands currently: - `llmfoundry registry get [--group]`: List all registries, and their components, optionally specifying a specific registry. Example usage: `llmfoundry registry get --group loggers` or `llmfoundry registry get` - `llmfoundry registry find
