Google Research is the research division within Google that focuses on building the next generation of artificial intelligence, machine learning, and computing tools. It works on both short-term projects that improve Google's products and longer-term research into how AI systems can learn and improve.
Google Research develops tools and frameworks that other developers and scientists can use freely. In October 2026, the team released Harness², an open-source framework that helps AI agents improve at tasks without needing to retrain their underlying models. Instead of rewriting the model, researchers and developers tweak how the agent is set up, which saves time and computing power.
Google Research also shares its work at major events. Its researchers have spoken at conferences such as MIT's EmTech Future, where experts discuss how AI is merging with other fields like science and industry.
Google Research is part of Google (which is under the parent company Alphabet). It employs researchers, engineers, and PhD-level scientists who publish findings, release open-source software, and collaborate with universities and other institutions around the world. The division has a long history, including earlier programs such as offering PhD degrees through its research group.
In recent years, the team has continued to release practical tools that let others build better AI systems without starting from scratch. Harness² is one example of this approach: give away the tool, let the community improve it, and advance the field together.
What is Google Research? Google Research is the artificial intelligence and technology research division of Google. It runs studies, builds new tools, and publishes its findings so that researchers and developers everywhere can use them.
What is Harness²? Harness² is an open-source framework from Google Research that lets AI agents get better at tasks without retraining the model behind them. Developers adjust the agent's setup instead of rebuilding the core AI, which is faster and less expensive.
Does Google Research work only on Google products? No. Google Research publishes many tools and findings for the public, including open-source frameworks. Its work also reaches universities, other companies, and independent developers through conferences and shared software.
