Why build your own

Stop sending a Ferrari to haul copper pipe.

Frontier AI from OpenAI and Anthropic is a Ferrari. It's an amazing engine, priced like one, and most of your work never needs half of what it does.

Price for a 200A panel swap?

Usually $2,400 with permit. Want me to draft the quote?

Use it

Use a more powerful model that was trained on your specific business.

Built-in team chat

Your own chat for your business.

When training finishes, your model is ready in a chat that works just like ChatGPT or Claude. Invite your team and they sign in with their work email. Nothing to install.

Arrow can run it on your computers too.

Henderson wants the panel moved to the garage. What should I quote?

Going by your last three panel relocations: about $3,100 with permit, a day and a half for two guys. Want me to draft it in your usual quote format?

Yes, draft it.
