Blended Labs builds a school platform on Llama and reports 10 hours a week saved for teachers
Blended Labs, a German education software company, built AI tools for teachers, students and school administrators on Meta's open-weight Llama 3.1 models. In a Meta case study the company reports that teachers save an average of 10 hours per week and that over 10,000 users are on the platform. All figures are company claims.

What it took
Cost, team size and timeline were not disclosed in the sources.
The problem
Teachers and school administrators spend large amounts of time on routine work such as preparing worksheets, giving feedback, grading and reporting. Blended Labs, a German education software company, says most existing school software simply copies traditional paper practices into digital form.
What they built
Blended OS is a school management platform with AI built in. Its AI layer, called SphereAI, runs on Meta's Llama 3.1 models in 8B and 70B sizes. Llama is an open-weight model, meaning its files are published so a company can run them itself.
Teachers get a suite of more than 40 AI tools for worksheets, lesson plans, feedback, grading and analysis of student performance. Students get Lumi, an AI co-teacher for language learning and science, technology, engineering and maths, available around the clock. Administrators get AI help with admissions, performance reports and tracking teacher engagement.
How they did it
Blended hosts Llama in different ways. Some schools with privacy needs self-host it. Others use a managed inference service from Groq. The team added Microsoft's Azure Content Safety to filter prompts and answers so that students and teachers stay protected, and is adding Llama Guard Vision for image features.
The article also describes a feature in preparation: using Llama 3.2 11B Vision, students upload photos of paper homework and the system helps grade it. The sources give no team size, cost or build timeline.
Results
Blended's CEO says the Llama integration has transformed the educational experience for over 10,000 users. The company says the teacher suite saves teachers an average of 10 hours per week, and students using Lumi saw a 22% improvement in learning outcomes. It also says schools using Blended OS cut operational costs by 18%.
All figures are the company's own claims as reported by Meta, and the article does not explain how they were measured.
What to copy
Start with the repetitive tasks that eat teacher time, offer privacy-conscious schools a self-hosted option, and ask the vendor how each claimed gain was measured before you rely on it.
Lessons for your project
Ask which teacher tasks the tools replace. Blended targets worksheets, lesson planning, feedback and grading, where time savings are easiest to measure.
Define outcome measures before claiming them. The 22% learning gain here has no stated method, so a school buyer would need to test it locally.
Offer hosting choices. Blended supports self-hosting for schools with privacy needs and a managed service for others.
Add content filtering for children. Blended layered a safety filter over the model before using it in classrooms.
Caveats
- Every figure comes from Blended Labs' own statements in a Meta case study. No independent source confirms them, and the page does not explain how the 22% and 18% figures or the 10 hours were measured.
- The page gives no go-live date. The deployed date shown is the article date.
- Meta's article also describes a new Llama 3.2 11B Vision feature for grading paper assignments that was being launched, with an expected extra four hours per week saved. That is a forecast and is not counted as a result.
- The wider Blended platform includes non-AI features, so the cost figure may not come from the AI tools alone.
