GoGuardian: Safer schools, empowered teachers, thriving students
GoGuardian · United States
GoGuardian, which powers safe, focused learning for half of U.S. K-12 students, migrated its ML infrastructure to Databricks to manage billions of daily inferences for web filtering, classroom management and harm prevention while maintaining a PII-free, COPPA/FERPA-compliant data environment. Using Delta Lake, Lakeflow, Unity Catalog, MLflow and Databricks Model Serving, GoGuardian achieved up to 50% reduction in machine learning operational costs, 90% operational cost savings with its Delphi website classification model, and a 62% reduction in inappropriate device use among students. AI-driven prioritization also cut the volume of records requiring human review for high-risk content by over 95%, from 1 million to 35,000-45,000.
Overview
GoGuardian, which powers safe, focused learning for half of U.S. K-12 students, migrated its ML infrastructure to Databricks to manage billions of daily inferences for web filtering, classroom management and harm prevention while maintaining a PII-free, COPPA/FERPA-compliant data environment. Using Delta Lake, Lakeflow, Unity Catalog, MLflow and Databricks Model Serving, GoGuardian achieved up to 50% reduction in machine learning operational costs, 90% operational cost savings with its Delphi website classification model, and a 62% reduction in inappropriate device use among students. AI-driven prioritization also cut the volume of records requiring human review for high-risk content by over 95%, from 1 million to 35,000-45,000.
The challenge
GoGuardian needed to manage 4 to 6 billion ML inferences daily across fragmented, disconnected services spanning data management, ML development, model serving and monitoring, causing operational and cost inefficiencies. The company also needed to maintain strict compliance with COPPA and FERPA through a PII-free, privacy-first data environment, while manual data labeling for sensitive use cases like self-harm detection became a bottleneck slowing development.
The solution
GoGuardian migrated to Databricks, using Delta Lake to bring structure and reliability to their AWS S3 environment. They implemented Databricks Lakeflow for a real-time ingestion pipeline with dbt for SQL-based transformations including hashing logic to remove sensitive student data. Serverless infrastructure eliminated manual cluster management, Unity Catalog provided unified governance and access control, MLflow gave end-to-end control over the ML lifecycle, and Databricks Model Serving scaled models — including their proprietary Delphi website-classification model — to meet real-time demands, all within a PII-free environment for data preparation and transformation.
Reported business value
GoGuardian's operational costs for machine learning services dropped by up to 50% across key use cases, with the Delphi website classification model achieving up to 90% savings compared to previous AWS deployments. Schools using GoGuardian's filtering solutions reported a 62% reduction in inappropriate device use among students. AI-driven prioritization of high-risk content cut the volume of records requiring human review by over 95%, from 1 million records to 35,000-45,000.

Open Universities Australia triples lead qualification with generative AI agents
Open Universities Australia (OUA) used LivePerson's AI Studio to build an LLM-powered generative AI agent that handles initial prospective-student inquiries, replicating the conversational style of human advisors. The agent achieved 3x lead qualification rates compared to self-searching students and 2x compared to OUA's prior scripted chatbot, with an average response time of 6.3 seconds versus roughly 2 minutes for human advisors.
Miami Dade College boosts student pass rates by 15% with Microsoft 365 Copilot
Miami Dade College deployed Microsoft 365 Copilot among its President's Cabinet and senior leaders, and used Microsoft Copilot Studio to build AI-powered assistants supporting personalized learning, coding exercises, essay structures and math problems around the clock. In the first semester of implementation in STEM and advanced analytics courses, the college saw a 15% increase in student pass rates and a 12% decrease in dropout rates. A survey found 77% of users completed tasks faster, 76% saw improved work quality, and 81% reported increased productivity; if just 15% of MDC's more than 6,000 employees saved 12 minutes a day, that would total nearly 50,000 hours a year. Encouraged by these results, MDC expanded its Copilot deployment by 400 licenses, prioritizing student-facing employees.
Harvard Medical School's Walter Lab runs 1.7 million protein interaction predictions using NVIDIA DGX Cloud
The Walter Lab at Harvard Medical School, with access to NVIDIA DGX Cloud through the National Science Foundation's NAIRR pilot program, completed nearly 1.7 million protein-protein interaction predictions on ColabFold in three months using 32-node DGX clusters with 256 A100 GPUs, a task that previously would have taken years. The team curated 40,000 high-confidence protein interactions among 300 human genome maintenance proteins using two custom ML tools (KIRC and SPOC), publishing results via the Predictomes website.
Lola - Success story at the University of Murcia
The University of Murcia deployed the chatbot Lola, built by 1MillionBot, to handle student queries during registration and university entrance exam periods. Lola has logged over 74,000 unique conversations with about 25,000 students, with a 93.4% accuracy rate. In June-July 2019, Lola answered queries from 5,525 users across 12,247 conversations and 34,423 messages, resolving 94.2% of queries, versus 28,000 inquiries handled by staff the year before implementation.
