LLM Cost Optimization — Cut Your AI Bill 40–70%
If your OpenAI or Anthropic bill is rising faster than your usage, you're paying for waste. We audit your LLM spend, route requests to the right-sized model, cache aggressively, and tune prompts — typically cutting bills 40–70% without dropping accuracy.
Composite from recent audits — exact mix varies by workload.
- Prompt caching — 35%
- Anthropic / OpenAI / Bedrock cache for system prompts and tool definitions.
- Model right-sizing — 30%
- Route easy 80% to Haiku / 4o-mini after eval-verified switch.
- Prompt diet & compression — 20%
- Trim system prompts, drop unused tool defs, compress context.
- Streaming + batching — 10%
- Use streaming where UX matters, batch where it doesn't.
- Retrieval cleanup — 5%
- Smaller chunks, smarter k, less context bloat.
Numbers are typical, not a quote. The audit gives you the real projection for your workload.
What you get
When it fits
- Monthly LLM spend is already painful ($20k+/mo) or growing fast
- Latency is a real product issue — users wait, conversion drops, on-call gets paged
- You have evaluation signal (or are willing to create it) so we can downsize models with confidence
- Someone owns the bill — finance, engineering leadership, or the platform team
When it doesn't
- The spend is genuinely small — premature optimization will cost more than it saves
- You can't measure quality, so we can't prove the cheaper model is good enough
- The accuracy floor is regulatory — sometimes the expensive model is required and we'll tell you
Process
Week 1: audit — spend by model, feature, and prompt; eval-coverage check. Weeks 2–3: build the eval harness for the top 3–5 use cases. Weeks 4–6: implement model routing, caching, and prompt diet behind feature flags. Week 7: rollout and dashboard handover. Most clients see the first ~25% cut by week 3.
Full delivery processPricing
Fixed-fee audit ($10–20k) — produces savings projection and is creditable against implementation. Implementation runs $40–120k depending on surface area. Outcome-based pricing available when current spend is high enough that the math works for both sides.

- Will accuracy drop?
- No — the eval harness is the gate. We don't downsize a model until the eval shows the smaller model meets or beats the larger one on your real data. If a use case can't be downsized, we leave it alone.
- Which providers do you work with?
- OpenAI, Anthropic, AWS Bedrock, Google Vertex, Azure OpenAI, and open-source via vLLM or together.ai. We're agnostic — the routing layer can mix providers, and many of our biggest savings come from running the right model on the right provider.
- How quickly do we see savings?
- Typically a 20–30% cut by week 3 from prompt caching alone — that's the lowest-hanging fruit and often the single biggest lever. Full 40–70% reduction usually lands by week 6–8 once routing and eval-verified downsizing are deployed.
- Is this a one-time engagement or ongoing?
- Either. Most clients take a fixed-fee implementation, then a quarterly check-in to catch creep — new features, new models, new prompts that drift. LLM cost is a living target; one cleanup doesn't last forever.
