Stop Guessing Your OpenAI API Costs
Track every GPT-4, GPT-4o, and o-series token in real time. Set budget alerts, detect anomalies, and reduce your OpenAI bill by up to 60%.
The OpenAI Cost Problem
OpenAI's billing dashboard updates once a day and gives you a single dollar number with no breakdown by model, feature, or user. When your engineering team ships a new agent or chains GPT-4 calls together, costs can spike 10× overnight — and you won't see it until the invoice arrives.
AI Cost Guard solves this by attaching to every API call at the SDK level. You get per-request cost attribution, real-time dashboards, and automated alerts before your budget is blown — not after.
What You Get
Real-Time Cost Dashboard
See GPT-4, GPT-4o, and o-series costs update within seconds. Filter by model, project, environment, or user.
Budget Alerts & Auto-Stop
Set daily / monthly spend caps. Get Slack or email alerts at 50%, 80%, and 100% — or auto-pause calls at your limit.
Anomaly Detection
AI-powered spike detection flags unusual cost patterns (e.g., 3× normal token usage) and sends a push notification instantly.
Token-Level Attribution
Every request is logged with model, prompt tokens, completion tokens, latency, and cost. Group by feature, endpoint, or team.
Model Mix Optimization
AI Autopilot analyses your prompts and suggests cheaper models (e.g., move from GPT-4 to GPT-4o-mini) with quality-score validation.
Duplicate Prompt Detection
Detect repeated prompts automatically and cache responses to slash redundant API calls by up to 40%.
Two-Line Integration
Wrap your existing OpenAI SDK in the AI Cost Guard proxy — no code refactor, no infrastructure changes.
import { CostGuard } from '@aicostguard/sdk';
// Wrap your OpenAI client — that's it
const guard = new CostGuard({ apiKey: 'cg_...' });
const openai = guard.wrap(new OpenAI());
// Use openai as normal — costs tracked automatically
const chat = await openai.chat.completions.create({
model: 'gpt-4o',
messages: [{ role: 'user', content: 'Hello!' }],
});Supported OpenAI Models
AI Cost Guard tracks pricing for every OpenAI model including:
Frequently Asked Questions
How does AI Cost Guard monitor OpenAI costs?+
AI Cost Guard integrates via a lightweight SDK proxy. Every API call to OpenAI flows through a two-line wrapper that logs tokens, latency, and cost in real time — with zero overhead.
Does it work with GPT-4o-mini and o3?+
Yes. AI Cost Guard supports all current OpenAI models including GPT-4, GPT-4o, GPT-4o-mini, GPT-4 Turbo, o1, o1-mini, o3, o3-mini, o4-mini, and the new GPT-4.1 family.
Can I set budget limits on OpenAI spend?+
Absolutely. Budget Guard lets you set daily, weekly, or monthly spend caps per project. When a threshold is reached you get a Slack / email alert — or auto-stop to prevent overruns.
How fast does tracking show up?+
Costs appear in the dashboard within seconds of the API call completing. Aggregates (daily, weekly, monthly) refresh every 60 seconds.
