# Browse Models Learn how to effectively search and discover biological models in the Biosimulant catalog. **Time estimate**: 10 minutes ## Goal By the end of this tutorial, you'll be able to: - Search for models by name and keyword - Filter models by standard and catalog metadata - Understand the key metadata exposed on a model page - Open a model in a lab and continue from there ## The Model Browser Navigate to **Models** in the top navigation to access the model browser. ### Search Bar The search bar supports: - **Model names**: "Lotka-Volterra", "Glycolysis" - **Keywords**: "cancer", "metabolism", "signaling" - **Repository slugs**: "demo/mapk-cascade" **Tip:** Start with a broad keyword, then narrow with filters. The exact search grammar may vary across product tiers or workspaces. ## Filtering Models ### By Model Standard - **SBML**: Systems Biology Markup Language - biochemical pathway models - **NeuroML**: Neural models for computational neuroscience - **CellML**: Physiological models for cell biology - **NMODL**: NEURON MOD files for neural simulation - **ONNX**: Machine learning models for hybrid simulations ### By Catalog Metadata - **Tags**: domain labels, curation labels, or workflow labels - **Visibility/source**: public catalog versus items attached to your account, when exposed - **Recently updated** or similar sort orders, when exposed by the UI ## Model Details Click on any model to see: ### Overview Tab - **Description**: What the model represents - **Package identity**: Package name and version, if present - **Standard**: SBML, NeuroML, ONNX, or other - **Tags and metadata**: Public discovery fields attached to the model ### Package and Interface Details - **Entrypoint** or packaged artifact details - **Declared parameters** or configurable module inputs, when available - **Manifest-backed metadata** from the package or linked repository ### Versions and Linked Assets - **Current version** and update history, when versioning is enabled - **Source repository** or upload provenance, when available - **Labs using this model**, when the UI exposes related labs ## Opening a Model in a Lab 1. Open the model detail page 2. Choose **Open in Lab** or the equivalent action in your UI 3. Review the generated or linked lab configuration 4. Start a run or save the lab for later ## Best Practices 1. **Start broad, then narrow**: Begin with general terms, add filters as needed 2. **Check package metadata**: Model quality varies; versioned and clearly described packages are easier to trust 3. **Open the lab before running**: This makes it easier to inspect defaults and overrides 4. **Compare related models**: Multiple models may represent the same system differently ## Next Steps - [Run a Simulation](/how-to/web/run-simulation) - Execute a model you've found - [Biosimulant Library](/references/library) - Work with models in Python
