Caveman Router.
Same agent. Up to 60% cheaper.
It gives every task in Claude Code the cheapest model that can do it. You change nothing about how you work.
Your agent overpays for easy work.
Claude Code hands work to subagents: one searches the repo, one reads files, one runs the tests. Much of it is simple, and it often runs on the same expensive model as the hard problems.
Caveman already cut the words.
The Caveman skill gets coding agents to drop the filler: about 65% fewer output tokens, in Claude Code, Codex and 30 more agents.
Now Caveman picks the model.
Simple work goes to a small model. Hard problems still get the frontier one. That split is where the saving comes from.
Watch one decision.
A subagent spawns. Keep scrolling to see what the router reads before it starts.
Example subagent“Find where the session token gets refreshed.”
- Taskcode search↓ small
- Complexityspans 3 services↑ mid
- Cachecoldstays
Left alone, it runs on the lead’s frontier model, the most expensive one.
It’s a search with an answer you can check. A small model can do that.
But the answer spans three services. Tracing it takes more reasoning, so it steps up.
It starts from a fresh context, so there’s no warm cache to lose by switching.
Mid model. Strong enough for the job, cheaper than the default.
Seven more signals count on every spawn: reasoning effort, context size, tools, subagents already running, provider health, your plan and price.
Keep your agent. Keep your plan.
Same Claude Code, same Pro or Max plan. Or add more models, your call. When a subagent moves, you see one line:
Caveman · subagent on Sonnet 5 instead of Opus 5 · est. $0.84 vs $1.72 · code search
Example output
Bring any model
- OpenRouter
- OpenAI
- Anthropic
- Meta
- Mistral
- DeepSeek
- and more
Through OpenRouter or any OpenAI-compatible provider, on your own key.
If it fails, nothing changes.
No key, a slow answer, a bad reply: the task runs exactly as your agent asked. One command turns routing off.
