It provides over 20 high-performance LLMs, along with comprehensive recipes and tools to pretrain, finetune, and deploy them at scale. With a strong emphasis on minimal abstractions and full control, LitGPT ensures blazing fast, minimal, and performant solutions suitable for enterprise-scale AI applications.\n\n## Installation\n\nGetting started with LitGPT is straightforward. You can install it using pip:\n\nbash\npip install 'litgpt[extra]'\n\n\nFor advanced options, including installing from source, refer to the official documentation.\n\n## Examples\n\nLitGPT offers a simple yet powerful API for interacting with LLMs. Here's a quick example of loading an LLM and generating text:\n\npython\nfrom litgpt import LLM\n\nllm = LLM.load(\"microsoft/phi-2\")\ntext = llm.generate(\"Fix the spelling: Every fall, the family goes to the mountains.\")\nprint(text)\n# Corrected Sentence: Every fall, the family goes to the mountains.\n\n\nBeyond simple inference, LitGPT provides a command-line interface (CLI) for advanced workflows. You can easily finetune, serve, or chat with models:\n\nbash\n# Finetune a model\nlitgpt finetune microsoft/phi-2 --data JSON --data.json_path my_custom_dataset.json --out_dir out/custom-model\n\n# Deploy the model\nlitgpt serve out/custom-model/final\n\n# Chat with a model\nlitgpt chat microsoft/phi-2\n\n\n## Why Use LitGPT\n\nLitGPT stands out for several reasons, making it an excellent choice for LLM development:\n\n*   **Enterprise Ready**: Released under the Apache 2.0 license, it's suitable for unlimited enterprise use.\n*   **Developer Friendly**: Features easy debugging due to no abstraction layers and single-file implementations.\n*   **Optimized Performance**: Models are designed to maximize performance, reduce costs, and speed up training, incorporating state-of-the-art optimizations like Flash Attention v2 and multi-GPU support.\n*   **Proven Recipes**: Comes with highly-optimized training and finetuning recipes, validated at enterprise scale.\n*   **Extensive Model Support**: Offers over 20 LLMs, including popular ones like Llama, Gemma, Phi, and Mixtral, all implemented from scratch for maximum performance.\n*   **Advanced Features**: Supports low-precision settings (FP16, BF16), quantization (4-bit, 8-bit, double quantization), and Parameter-Efficient Finetuning (PEFT) methods like LoRA, QLoRA, and Adapter.\n*   **Community and Research**: LitGPT has powered significant AI projects, including TinyLlama and the NeurIPS 2023 LLM Efficiency Challenge, showcasing its robustness and impact.\n\n## Links\n\nExplore LitGPT further through these official resources:\n\n*   **GitHub Repository**: [https://github.com/Lightning-AI/litgpt](https://github.com/Lightning-AI/litgpt){target=\"_blank\"}\n*   **Discord Community**: [Join the LitGPT Discord](https://discord.gg/VptPCZkGNa){target=\"_blank\"}\n*   **Tutorials**: Dive into detailed guides on [Getting Started](https://github.com/Lightning-AI/litgpt/blob/main/tutorials/0_to_litgpt.md){target=\"_blank\"}, [Finetuning](https://github.com/Lightning-AI/litgpt/blob/main/tutorials/finetune.md){target=\"_blank\"}, [Pretraining](https://github.com/Lightning-AI/litgpt/blob/main/tutorials/pretrain.md){target=\"_blank\"}, and [Deployment](https://github.com/Lightning-AI/litgpt/blob/main/tutorials/inference.md){target=\"_blank\"}.","metrics":{"detailViews":7,"githubClicks":14},"dates":{"published":null,"modified":"2026-01-04T16:01:17.000Z"}}
