# LMFlow vs llmflows

*GraphCanon updated Aug 16, 2026*

## Verdict

Pick LMFlow if lMFlow is an extensible Python toolkit for fine-tuning and inference on large foundation models with Gradio-based chatbot deployment; pick llmflows if lLMFlows is designed for developers seeking a streamlined way to build and deploy language model applications with an emphasis on transparency and simplicity.

[LMFlow](https://optimalscale.github.io/LMFlow/) reports 8.5k GitHub stars, 825 forks, and 88 open issues, last pushed May 22, 2026. [llmflows](https://llmflows.readthedocs.io) has 707 stars, 35 forks, and 19 open issues, last pushed Feb 20, 2025. Figures are from public GitHub metadata via [LMFlow's repository](https://github.com/OptimalScale/LMFlow) and [llmflows's repository](https://github.com/stoyan-stoyanov/llmflows).

## Choose when

### Choose LMFlow if…

- License: LMFlow is Apache-2.0, llmflows is MIT.
- Tags unique to LMFlow: deep-learning, instruction-following, language-model, pretrained-models.
- You require an extendable framework to fine-tune or conduct inference operations on large foundational models where a user-friendly chatbot UI can be integrated using Gradio.

### Choose llmflows if…

- License: llmflows is MIT, LMFlow is Apache-2.0.
- Tags unique to llmflows: ai, gpt-4, llm, llm-inference.
- If you need a Python framework that prioritizes the clarity and ease of use in developing language model apps.

## When NOT to use LMFlow

- You do not need a Python-based solution for your large foundation model tasks, or if your projects specifically require languages other than Python.
- Your project requires commercial use with simplified authorization processes, since LMFlow demands signing a specific document to obtain authorization for commercial use.

## When NOT to use llmflows

- Do not choose LLMFlows if advanced customization or integration with more complex frameworks is required for your project.
- Avoid using this tool in scenarios where you need real-time adaptive features that are highly dynamic, as LLMFlows emphasizes explicitness which can limit flexibility.
