The title feels misleading. Why clickbait on that when you can just be genuine about the architecture?
Is RAG dead? I would be very surprised a local small SOTA embedded model like llama-embed-nemotron-8b doesnt outperform the Haiku layer for this application. Should be pretty cheap and easy to prove out. With 32K context size, you can literally one shot the whole ticket.
Looking at the diagram, is this seriously a case of replacing basic functional concepts like "write to clickhouse" or "have we seen this before" to a model? could those be actual function calls in some language?
just seems wasteful all around. having an agent in the critical path when a regular expression (or similar) could do just seems odd. yeah haiku is cheap but re.match() is cheaper.
I do a similar thing with a "planner agent" that uses the cheapest (I think it's using openai-gpt-5.2-mini or something at like 20 cents for 1M.) that more or less emits a plan name, task list and the task list has a recommended model in each task. It's not perfect, but many of our tasks are accomplished with lighter weight models. When doing code generation or fixing we upgrade to a more expensive model, planning and decisions are done more cheaply. Keep in mind the tasks are relatively constrained, so planning done with a cheap agent makes sense here. An open-ended agent would likely use a more expensive call for planning.

“Let a cheap agent decide if the expensive one is needed.”
