View all →Harness Engineering: Why the Scaffolding Around the Model Is the Real Source of Agent Power
Frontier models are converging, so the real differentiator has moved to the harness — the engineered scaffolding of context, tools, loops, verification, and memory wrapped around the model. Here is how harness engineering works, dissected across Claude Code, Cursor, and Devin, and why it produces what we call hyper agents.
Crusoe
An AI-first cloud built on cheap, clean power — on-demand GPU clusters (H100s up to GB200 NVL72), managed Slurm/Kubernetes, and managed inference. The compute layer that removes the hardest blockers to fine-tuning and serving your own models.
Pi
A minimal, open-source coding agent that lives in your terminal — read/write/edit/bash out of the box, then bent to your workflow with TypeScript skills, sub-agents, and 15+ model providers you can swap mid-session. The hacker’s coding agent.
