From Rising AI Costs to
Smarter Model Usage.

We helped a growing AI product reduce unnecessary model spend and improve response speed by matching each task to the right model, reducing repeated work, and tracking cost by feature and workflow.

What We Set Out to Improve.

Business
AI-Enabled SaaS Company

A growing business looking to use AI in a practical way without creating more complexity for teams or customers.

Partnership
AI Cost & Performance Optimization

Coretus handled discovery, UX, AI workflows, integrations, testing, deployment, and ongoing improvement.

Goal
Lower AI Cost & Improve Response Speed

Make AI useful in daily operations while keeping the experience simple, measurable, and easy to manage.

What We Built
AI Cost & Performance Optimization Layer

A focused AI solution designed around the client's existing workflows, users, and business systems.

What Was Getting in the Way.

As product usage increased, AI costs became harder to predict. Expensive models were being used for tasks that did not always need them, and some requests were slower than users expected.

The company did not want to reduce AI capability. It wanted to use the right level of intelligence for each task and understand exactly where cost and response time were coming from.

Rising Model Cost
High-capability models were used even for simple requests.
Slow Responses
Long processing chains increased user wait time.
Poor Cost Visibility
The team could see the total bill but not which features were driving it.
The Solution

What We Built.

01
Measure Cost & Response Time
We tracked model usage, token consumption, processing time, retries, and feature-level AI activity.
Key details
Input Usage Cost Response time
Control Business Rules
Experience Simple For Users
02
Route Tasks Intelligently
Simple tasks were handled by lighter models while complex tasks used stronger models only when necessary.
Key details
AI Context Aware
Actions Smart Model Routing
Review Human When Needed
03
Reduce Repeated Work
Caching, better prompts, fewer unnecessary calls, and optimized context reduced avoidable model usage.

Before and After

How the Workflow Improved.

Area
Before
After
Model Choice

One Model for Everything

Most tasks used the same expensive model.

Task-Based Routing

Each workflow uses the level of model capability it needs.

AI Spend

Monthly Total Only

Teams lacked feature-level cost detail.

Cost by Workflow

Spend becomes easier to understand and control.

Response Speed

Long Chains

Some requests involved unnecessary processing.

Lean Workflows

AI calls and context are reduced where possible.

Key Features

What Made the Solution Useful.

MODEL ROUTING

Right Model for the Task

Different AI models can be selected based on task difficulty, risk, or response needs.

Business impact
Lower Unnecessary Cost
COST ANALYTICS

Feature-Level AI Cost

Teams can see which workflows and features consume the most AI resources.

Business impact
Better Budget Control
Response time OPTIMIZATION

Faster AI Workflows

Reduced calls, better prompts, and caching help improve response speed.

Business impact
Better User Experience
Faster Delivery

How We Reduced Build Time.

Tested foundations helped the team spend less time on setup and more time on the parts that made this product useful.

What accelerated the work

4 reusable building blocks
01

Secure Access

A tested starting point for secure access reduced repeated setup work.

02

AI Workflow Layer

Reusable work for ai workflow layer let the team focus more time on the client’s specific needs.

03

Monitoring & Feedback

This made it easier to add monitoring & feedback without rebuilding common foundations.

04

Human Review

A tested starting point for human review reduced repeated setup work.

How We Kept It Safe and Reliable.

01
Permissions
The AI only accesses information and actions that are approved for the user and workflow.
ACCESS CONTROLLED
02
Human Oversight
Important or unusual cases can be routed to a person before any sensitive action is taken.
HUMAN IN CONTROL
03
Activity Tracking
Key AI actions and outcomes can be recorded so teams understand what happened.
TRACEABLE
04
Continuous Improvement
Rules, prompts, workflows, and controls can be adjusted as usage patterns change.

Client Testimonial

In their own words.

The goal was not to make the AI cheaper by making it worse. We made the system smarter about when it actually needed the expensive model .
