Stop Sending Every Small Task to Your Strongest Model

Support classification, summarization, and structured extraction often run on a flagship model for a boring reason: the project connected one model early, and every later feature inherited it.

If you want to reduce AI cost, the first move is not replacing every request with a cheaper model. It is building a task-routing table.

Start with three task tiers

Task	Default path	Escalate when
Classification, short summaries, field extraction	Validate an efficient model first	Output fails, intent is unclear, or the rule does not apply
Knowledge-base Q&A, everyday coding help	Use a route that meets the quality bar	Grounding is missing or reasoning gets complex
Critical customers, complex code, high-risk decisions	Stronger model or human review	Do not force a downgrade

The third column matters as much as the first two.

“If it is not here tomorrow, I will decide whether to ask for a refund” should not be forced into either “refund” or “shipping.” It needs escalation or a human path.

Start automation with rules you can explain

The most useful kind of automatic model selection is not a black box that guesses every business intent. It begins with explicit task paths.

A support classifier can use one validated efficient route. A knowledge-base answer can use another. A critical content review can have a clear escalation rule.

zltokens can help a team put that routing table into its API workflow, so requests follow agreed rules. Teams can then inspect the model, usage, errors, and final charge in their usage records.

The practical benefit is simple: your cost is no longer determined by whoever last changed the default model.
