Agent harnesses, frameworks, and orchestration systems.
Every coding agent is chasing a smarter model. omp, a security researcher's 1.14-million-line fork of Pi, bet that the harness around the model matters more, and built an edit format good enough to make cheap models land edits on the first try. It's mostly right. It also ships pointed at your foot.
Omnigent is Databricks' bid to become the orchestration layer above coding agents — one YAML spec driving Claude Code, Codex, Cursor, and Pi behind a governance engine that agents cannot talk their way around.
LangChain, LangGraph, Claude Agent SDK, OpenAI Agents SDK, Flue, Pydantic AI, and NVIDIA's NeMo Agent Toolkit — compared through a hybrid self-hosting lens, with the marketing stripped off.
