Harness THE AI term that became increasingly important in 2026.

For a long time, AI discussions were mostly about the model.

Which model is better? Which benchmark was beaten? Which new release changed everything again?

But over time, it became clear that the model is no longer the only success factor.

We saw that again around Google I/O. In a Hard Fork interview, Sundar Pichai tied Google's agentic-coding gap partly to lacking developer surfaces like Claude Code or Cursor. Not model capability alone.

That is exactly where the harness comes in.

It is the layer around the model: tools, context management, agent runtimes, guardrails, hooks, memory, verification, and workflows.

So what is a harness exactly?

Was it a new invention, or did it gradually emerge over time?

And what does it mean for the future of AI?

We answer these questions in our latest article.
