For direct user interaction or coding problems, perhaps. But as API calls get cheaper, it becomes more realistic to use them for completely automated workflows against data-sets, or as sub-agents called from expensive SOTA models.

For example, in Claude, using Opus as an orchestrator to call Sonnet sub-agents, is a popular usage "hack." That only gets more powerful, as the Sonnet equivalent model gets cheaper. Now you can spawn entire teams of small specialized sub-agents with small context windows but limited scope.

Exactly.

I did create my own MCP with custom agents that combine several tools into a single one. For example, all WebSearch, WebFetch, Context7 exposed as a single "web research" tool, backed by the cheapest model that passes evaluation. The same for a codebase research

Use it with both Claude and Opencode saves a lot of time and tokens.

I'd be interested in seeing the source for this if you have a moment

Smart approach combining tools behind a single interface. The "cheapest model that passes evaluation" pattern is underrated.

One data point that might help with the research tool: not all APIs work equally well when called by agents. We scored 387 APIs on agent-friendliness and 54% fail the bar. The main gaps are no CLI tool (66%) and no machine-readable pricing (72%). If your research tool is helping agents pick APIs to integrate, the scores at clirank.dev/api/apis?sort=score could save the expensive model from wasting tokens on APIs that'll fail headless.

Seems like a huge waste of money and electricity for processes that can be implemented as a traditional deterministic program. One would hope that tools would identify recurrent jobs that can be turned into simple scripts.

It depends on the specific task.

For example: "Here our dataset that contains customer feedback comment fields; look through them, draw out themes, associations, and look for trends." Solving that with a deterministic program isn't a trivial problem, and it is likely cheaper solved via LLM.

It makes sense if the dataset is so large that LLM cost is a prohibitive factor. Otherwise a frontier LLM has the advantage of producing a better result.

That is a very complex, high level use case that takes time to configure and orchestrate.

There are many simpler tasks that would work fine with a simpler, local model.
