Cut your LLM bill.Pay only from what we save.
Rakuvo audits your AI model spend, finds the waste, and proves every change on your own prompts before you switch.

The problem
LLM bills grow faster than usage, and most of the waste is fixable.
~$8.4B
Enterprise spending on LLM APIs more than doubled in six months, according to Menlo Ventures. Agent workflows make it worse: they send far more tokens per task than a chatbot.
~50%
Providers already offer big discounts for cached prompts and batch jobs that many teams never switch on. And swapping a big model for a small one saves money only if quality holds, which almost nobody checks.
How it works
Find it. Prove it. Ship it.
- 01
Export usage
Send us a read-only usage export or request logs (OpenAI, Anthropic, Gemini, LiteLLM, Langfuse, Helicone). No code access, no API keys.
- 02
Audit
We find caching, batching, model-size and context waste, and give each one a savings range with the assumptions shown.
- 03
Prove
Before any switch, we replay a sample of your own prompts on the cheaper setup and measure agreement and cost.
- 04
Ship & share savings
We help roll out the changes with a fallback. You pay a share of the savings we verify, and nothing if there are none.
Proof, not promises
A cheaper model can be 80% cheaper and still change your results.
We classified 38 support tickets with GPT-4.1, then replayed the same prompts on smaller models and measured both cost and agreement.
| Switch | Measured cost | Same label | Every field identical |
|---|---|---|---|
| GPT-4.1 → GPT-4.1 mini | ~80% cheaper | 89–92% (34–35/38, two runs) | ~70% |
| GPT-4.1 → GPT-4.1 nano | ~95% cheaper | 87% (33/38, one run) | ~70% |
The gap comes from one subjective field (urgent) that the smaller models set differently. The replay shows exactly which field diverges, so you decide before you switch. Small test: 38 AI-generated tickets, one task. Results moved between runs (34 vs 35 of 38 for mini), which is itself the point: measure on your own prompts, and re-measure. It illustrates the method; it is not a benchmark.
