Quick Deployment with the Litmus CLI:** - This is the easiest way to set up Litmus. - Make sure you have the Google Cloud SDK installed and configured with the correct project. - Install the Litmus CLI: - **Linux**: - install:`curl https://storage.googleapis.com/litmus-cloud/install/linux.sh | sudo sh` - binary: [https://storage.googleapis.com/litmus-cloud/prod/linux/litmus](https://storage.googleapis.com/litmus-cloud/prod/linux/litmus) - sha256: [https://storage.googleapis.com/litmus-cloud/prod/linux/litmus.sha256](https://storage.googleapis.com/litmus-cloud/prod/linux/litmus.sha256) - **OSX**: - install:`curl https://storage.googleapis.com/litmus-cloud/install/osx.sh | sudo sh` - binary: [https://storage.googleapis.com/litmus-cloud/prod/osx/litmus](https://storage.googleapis.com/litmus-cloud/prod/osx/litmus) - sha256: [https://storage.googleapis.com/litmus-cloud/prod/osx/litmus.sha256](https://storage.googleapis.com/litmus-cloud/prod/osx/litmus.sha256) - Deploy Litmus: `litmus deploy` - Deploy the proxy service (optional): `litmus proxy deploy` - **The deployment script will:** - Create service accounts and grant necessary permissions. - Deploy the worker service and the API service to Cloud Run. - Deploy the proxy service to Cloud Run if you choose to. **2. Manual Setup:** - **If you prefer manual deployment:** - **Set up your Google Cloud project:** Enable the required APIs (Firestore, Cloud Run, BigQuery). - **Deploy the worker service:** Build a Docker image for the worker service in the `worker` directory and deploy it to Cloud Run. - **Deploy the API service:** Build a Docker image for the API service in the `api` directory and deploy it to Cloud Run. - **Deploy the proxy service:** Build a Docker image for the proxy service in the `proxy` directory and deploy it to Cloud Run. - **Configure API settings:** Create a `api/util/settings.py` file with your Google Cloud project ID, region, and other settings. - **Deploy the UI:** Deploy the user interface code in the `api/ui` directory to a web server (e.g., Nginx, Apache). - **Connect the UI:** Configure the UI to connect to the deployed API service. **3. Using Litmus:** - Access the web interface. - Create and manage test templates, defining test requests, expected responses, and LLM evaluation prompts. - Select your desired evaluation methods in your templates (Custom LLM Evaluation, Ragas, DeepEval). - Optionally configure your LLM client to use the proxy service. - Submit test runs, monitor progress, and analyze the detailed results, including LLM-based assessments. - Explore proxy data and understand your LLM usage patterns. --- ## License Apache 2.0; see [`LICENSE`](LICENSE) for details. ``` --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/tools/google-litmus`](/api/graphcanon/tools/google-litmus) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
