Cut your agent bill.
Prove every dollar.
Point your base_url at us. We cut your LLM bill —
quality-gated and measured to the dollar — and you pay only a share of
what we measurably save. One line of config, your own provider keys.
free tier · one line of config · your own provider key

One line. Your SDK and keys, unchanged.
The Optimizer is a drop-in, OpenAI-compatible proxy. Change the base URL, keep your provider keys (they pass straight through). The dashboard lights up with real, attributed savings within minutes.
# before
client = OpenAI(api_key=KEY)

)A commodity gateway is table stakes. The savings live above it.
Caching and routing are commoditized. Our defensible value is the layer on top — quality-bounded, call-efficient, agent-native, and a memory that makes your savings compound the longer you run through us.
Cache · route · fallback
Exact and semantic caching, model routing to the cheapest tier that holds quality, retry → fallback → circuit breakers. The commodity base — table stakes, done right.
Cut cost only when quality holds
An LLM-judge gates every downshift and cache hit against your threshold. Below the bar, we transparently fall back. We never serve you a degraded answer to save a dollar.
Buy quality with the fewest calls
Spend extra reasoning only where it changes the answer, and stop the moment it’s good enough — the opposite of best-of-N spam. ~74% of best-of-16’s gain at ~1.2 samples.
Optimize whole agent runs
Memoize tool calls, prune carried context, reuse plan templates across a 30–50-step run — where agent cost actually lives. Plain prompt-caching can’t touch this.
Every call walks the same path — cheapest first.
- 1 cache
the cheapest call is the one we never make
- 2 trace
make the call smaller — prune, memoize, dedupe
- 3 route
task-class → cheapest model that holds quality
- 4 verify-and-stop
spend extra compute only when quality requires it
- 5 quality gate
never serve below your threshold
- 6 meter
baseline vs actual = your savings, to the dollar
Bring us your highest-cost agent.
We’ll prove the savings on one workflow first — your support bot, your coding agent — then expand across your traffic.
