CTO Network - The harness is the product

Stop waiting for the next model. It's coming anyway, and it'll be better, cheaper and on every provider within a quarter. Frontier capability used to be the moat. It's now a commodity you rent by the token.

So the difference moved. It's no longer who has the smartest model. It's who has the best harness: the loop, the tools, the memory, the retries, everything that turns a model into something that finishes the job.

Without it, a four-hour task forgets step two, restarts from zero, and quietly burns a weekend of tokens in a retry loop. 😱

That's not a prompt problem. It's state, recovery, routing and cost control. Most teams are still hand-rolling their harness, or skipping it entirely and blaming the model.
