In 2025, we marveled at agents that could browse the web. Now in mid-2026, something fundamentally different has emerged: autonomous AI systems that combine deep research, infrastructure provisioning, code generation, and quality assurance into a single coherent workflow. This isn’t incremental improvement. It’s architectural evolution. And four open-source projects reveal the pattern. ...
