Pi, Hermes Make Harnesses Ownable

The next competitive layer is shifting from model access to control over the agent runtime that supplies context, tools, memory, permissions, and feedback.

• –Pi’s minimal, extensible design lets developers shape the workflow through skills, extensions, prompts, and packages rather than accept a fixed product architecture.
• –Hermes Agent pushes the opposite edge of the spectrum with persistent memory, self-generated skills, scheduled tasks, browser control, and long-running autonomy.
• –Open harnesses make model switching and self-hosting practical, reducing dependence on a single vendor’s interface, pricing, or product roadmap.
• –Custom harnesses are emerging across coding, evals, RL environments, research, design, and marketing, making orchestration a reusable engineering asset.
• –The hard problem is recursive improvement: models and harnesses must evolve together, with verification and safety controls preventing customization from becoming uncontrolled complexity.
