AI Stack Explained in 3 Layers (LLM, Agent Harness, Omnigent)
Databricks open-sourced Omnigent, a meta-harness that routes queries across multiple agent harnesses through one runner.
“So, Databricks open-sourced a fix, Omnigen. It's a meta harness. One layer that sits above every harness.”
Databricks open-sourced Omnigent, a 'meta harness' that sits above individual agent harnesses (like Claude Code or Codex) and routes a query to whichever agent fits, running them in parallel or orchestrating them via routers and orchestrators. It matters because it addresses agent siloing, where sessions and context can't cross between closed agent ecosystems, proposing interoperability as a new top layer of the AI stack.
