Experimental optimization algorithms and research prototypes under active development.

For new optimization techniques (quantization, pruning, sparsity, etc.) that are:

• Novel or research-stage algorithms
• Not yet production-ready
• May have unstable APIs

⚠️ Warning: Experimental features are not guaranteed to work across releases. APIs may change or features may be removed without notice. Use at your own risk.

Each experimental technique must include:

• README.md - Explains what the technique does, how to use it, current status, model support, and references
• Working code - Clear, readable implementation
• Comprehensive tests - Good test coverage demonstrating correctness
• Detailed documentation - Clear docs on usage, APIs, and behavior
• Example - Demonstrating usage
• Model support list - Which models/frameworks are supported
• Deployment info - Supported deployment frameworks (TensorRT-LLM, vLLM, SGLang, etc.) and whether custom kernels are required
• requirements.txt - Additional dependencies beyond base modelopt
• License headers - Apache 2.0 headers on all Python files

Organize your code however makes sense. Here are some examples:

Simple flat structure:

experimental/my_technique/
├── README.md
├── requirements.txt
├── my_technique.py
├── test_my_technique.py
└── example.py

Package structure:

experimental/my_technique/
├── README.md
├── requirements.txt
├── my_technique/
│   ├── __init__.py
│   ├── core.py
│   └── config.py
├── tests/
│   └── test_core.py
└── examples/
    └── example_usage.py

Experimental code must meet quality standards:

• Comprehensive test coverage required
• Clear documentation required
• Pass all pre-commit checks

Keep PRs focused and reviewable:

• Split large features: Break complex techniques into multiple PRs if needed
• Reasonable scope: PRs with tens of thousands of lines are difficult to review
• Incremental development: Consider submitting core functionality first, then enhancements
• If your technique is large, discuss the implementation plan in an issue first

Your technique's README.md should include:

# Your Technique Name

When a technique is ready for production (proven effective, stable API, full tests, comprehensive docs), it can be promoted to the main modelopt package.

Contributors: Open an issue proposing graduation with evidence of effectiveness and stability.

Users: If you find an experimental feature valuable, open a GitHub issue requesting promotion to production. User demand is a key signal for production readiness.

Open a GitHub issue with [experimental] prefix.
