AI Cost Optimization

Your AI bill is 3–5× higher than it needs to be.

We audit every LLM endpoint, deploy a smart routing layer, implement prompt caching, and install hard budget caps — cutting your API spend 40–80% within 30 days. No code changes required.

The Problem

Why AI bills spiral — and why most teams don't catch it.

Half of companies with AI-core products don't track LLM costs per feature. By the time someone notices the bill, the waste has been running for months.

01

Flagship models doing commodity work

GPT-4o and Claude Opus cost 15–60× more per token than smaller models. Most companies route every request through their best model by default — including simple classification, FAQ responses, and summarization tasks where a $0.00015/1k token model is equally accurate.

02

Zero prompt caching

If your system prompt is 2,000 tokens and you make 500,000 calls per month, you're paying to process that same prompt 500,000 times. Prompt caching alone — supported by OpenAI, Anthropic, and Google — typically cuts input costs 80–90% on repetitive workloads.

03

No cost attribution

Most engineering teams can tell you the total LLM bill but not which feature, team, or workflow is driving it. Without per-endpoint attribution, you're flying blind — you can't cut what you can't see.

04

No budget caps

A misbehaving agent loop, a retry storm, or a sudden traffic spike can burn through thousands of dollars before anyone gets a Slack notification. Hard budget caps with automatic cutoffs are a one-day implementation that most teams skip until it's too late.

The Audit

Ten things we look at in every AI cost review.

Most audits stop at "which model are you using." We go deeper — into prompt structure, call patterns, retry logic, and cost attribution gaps that your provider dashboard will never show you.

What We Build

Five levers. Every one compounds on the last.

We implement them in order of impact. Most clients hit 50% savings from routing alone before we touch anything else.

Biggest lever

Intelligent model routing

A drop-in proxy layer classifies each incoming request and routes it to the cheapest model that can handle it accurately. Complex reasoning goes to flagship models. Classification, summarization, and FAQ go to mini models. Typical result: 50–70% cost reduction before any other change.

Easiest win

Prompt caching

Static system prompts, few-shot examples, and repeated context blocks are cached at the API level. Every provider supports it. Most teams haven't turned it on. A single afternoon of implementation typically saves 40–60% on input token costs for high-volume features.

Compounding

Token optimization

We audit your prompt structure for redundancy, reformat outputs to use structured JSON instead of verbose prose, and eliminate token-expensive patterns like chain-of-thought where it isn't needed. Average reduction: 20–35% on top of routing and caching savings.

Risk control

Hard budget caps

Per-feature, per-team, and per-model hard limits with Slack and email alerts at 80% threshold and automatic cutoffs at 100%. Prevents a single runaway agent or traffic spike from destroying your monthly budget while your on-call engineer is asleep.

Visibility

Real-time cost dashboard

A CFO-readable view of your AI spend by feature, model, team, and day. Built on top of your existing logging infrastructure — no new data pipelines required. Delivered as a live Grafana, Retool, or Notion dashboard depending on what your team already uses.

The Process

Audit to savings in 10 business days.

Everything is done for you. You approve the routing rules before anything goes live.

01

AI Spend Audit

We review your API logs, endpoint structure, and current model selection. You walk away with a full cost attribution map and a ranked list of every optimization opportunity sorted by dollar savings.

02

Optimization Design

We design the routing rules, caching strategy, and token reduction changes specific to your architecture. No generic templates — the routing logic is built around your actual query patterns.

03

Deploy & Verify

The routing layer goes in as a drop-in proxy. Caching changes are applied. Budget caps are configured. We verify cost reductions on live traffic before handing anything over.

Monitor & Tune

Weekly cost review for the first 60 days. We tune routing accuracy as your query patterns evolve, catch model version upgrades that change cost profiles, and flag any new spend spikes.

Ongoing cost governance

Provider Support

Llama, Mistral, and self-hosted models on your infrastructure

FAQ

Questions before you book.

Everything engineering teams ask before the first call.

Do you need access to our codebase?

No. We work from API logs and usage dashboards. We need read access to your LLM provider usage reports (OpenAI, Anthropic, Google) and a 30-minute call with your engineering lead. No code access required for the audit phase.

Which AI providers do you support?

OpenAI (including Azure OpenAI), Anthropic, Google (Vertex and AI Studio), AWS Bedrock, and Groq. If you're running open-source models on your own infrastructure, we can audit those too — the optimization principles are the same.

What if we're on an enterprise contract?

Enterprise contracts typically come with volume commitments, not discounts on wasted usage. Reducing your token consumption by 60% on an enterprise plan directly reduces your next renewal benchmark — and makes your actual usage cost materially less. We optimize usage; you renegotiate contract rates on top.

How long from audit to savings?

The audit takes 2–3 business days. Routing and caching deployment takes 3–5 days. Most clients see verified savings within 10 business days of the first call. Budget caps and dashboards are typically live within the first week.

Does model routing reduce quality?

Only if the routing rules are wrong. We validate every routing decision against your actual outputs before going live. The rule is simple: a query gets routed to a cheaper model only if that model has been benchmarked to match flagship quality on that specific task type. If it doesn't match, it stays on the flagship model.

Is this a one-time engagement or ongoing?

Both options are available. The audit and initial optimization is a one-time fixed fee. Ongoing monitoring — weekly cost reviews, routing tuning as your product evolves, and catching model version changes — is a monthly retainer. Most teams start with the one-time engagement and move to retainer after seeing the first results.
