Ex-DeepMind engineer open-sources A11, thin layers instead of heavyweight agent frameworks
helenapnkv · reddit · 2026-09-07
A developer who worked at Google DeepMind (now at JetBrains) released A11, an open-source continuation of Action Engine. His thesis: agent frameworks that define your agent for you become another thing to work around once demos turn into real features—problems with streaming, state, remote execution, cancellation, and subagent discovery recur across teams, including Genie 3/Veo at DeepMind. A11 offers deliberately thin, single-purpose layers around two plain concepts: Actions (executable code with I/O schemas and lifecycle behavior, registered in an ActionRegistry) and nodes, designed to fit existing applications rather than force apps into a framework's control flow.
