Claims
- The AI model is no longer the core product; orchestration systems built around models are.
- An agent harness defines the rules governing how an agent loops and acts.
- Codex, Perplexity Computer, and Claude Code are all examples of model-plus-harness orchestration systems.
Key quotes
The model is no longer the product. Codex, Perplexity Computer, or Claude Code - all are orchestration system. It takes a model and pairs it with an agent harness.
What is an agent harness? The rules for how the agent loops around.
