Customers running GitLab Duo Agent Platform Self-Hosted operate under constraints many software teams don’t face: data residency mandates, air-gapped networks, and compliance regulations that prohibit sending source code to third-party APIs. Those constraints also come with a trade-off. The most capable models tend to land in cloud-first deployments, leaving regulated and isolated environments a step behind on AI capability, and forcing teams into a single-model setup that’s either overkill for routine work or underpowered for complex agentic tasks.
