You think it is hard to export an agent? It's a master prompt, a collection of documents and a few generic plugins like function calling and code execution. This will be implemented in open source soon. You can even fine-tune on your bot logs.
My company will be all over this.
We 'could' continue to use open-source components we're gluing together ourselves.
But risk-aversion and speed-of-iteration are key for us. We'll throw money at a reliable end-to-end solution with solid infrastructure.
