With Amazon Lookout for Vision, you pay only for what you use. There is no up-front commitment or minimum fee. After you create a project and upload baseline images, Amazon Lookout for Vision lets you detect anomalies by training a customized defect detection machine learning (ML) model on your manufacturing lines. There are two components that determine your bill: charges for training the model (training hours) and charges for detecting anomalies (inference hours).

Training Hours

You pay for the number of hours it takes to train your defect detection model. Amazon Lookout for Vision can provision multiple compute resources in parallel to quickly train your model. For example, Lookout for Vision might provision three compute resources to run simultaneously. Each resource, using three different algorithms, runs for 30 minutes. You then pick the best algorithm for your model. This means that you will have a trained model ready for use within 30 minutes, but the number of hours billed will be 1.5 hours (30 minutes x 3 algorithms).

Inference Hours

You pay for the number of hours you detect anomalies or defects with your customized model. To find defects using your model, Lookout for Vision provisions a minimum of one compute resource, known as an inference unit. You can increase or decrease your defect detection capacity depending on manufacturing line demands by requesting additional inference units. Each additional inference unit increases your processing speed by one inference unit. You are billed per inference unit/per inference hour that you use your defect detection model. For example, if you’re using two inference units and you use the model for eight hours (start at 9 AM and stop at 5 PM), you would be billed 8 x 2 = 16 inference hours. If you do not explicitly stop using your model, you will continue to be charged even if you are not actively detecting anomalies using the model.

Pricing table

Amazon Lookout for Vision Training and Inference usage is billed on minute increments, with a minimum of one minute.

Pricing examples

Example 1: Finding weld defects in automobile engine assembly

Let’s say you’re an automobile manufacturer. You want to identify weld defects in all the engines assembled in your factory using Lookout for Vision. For simplicity, assume for eight hours a day, every minute, one engine unit is inspected for weld defects before it is sent to the next stage of your assembly line. The first bill at the end of the month (22 days, assuming no weekend usage) using Amazon Lookout for Vision in US East (N. Virginia) would be calculated as follows:

Monthly training and inference hour charges
Assume it takes three training hours to train your model. You’re using inference hours on a daily basis (8 hours/day x 22 days) for 176 inference hours. On the first day, you use three training hours and four inference hours, and you can leverage the free tier for this usage. For the remaining time, you would incur charges as detailed in the table below.

Usage type Hours used Price Free tier usage Number of billable hours Charge for the month 
Training 3 hours

$2.00/hour

3 hours (max 10 per month)

0 0
Inference tier 1 176

$4.00/hour

4 hours (max 4 per month)

176 - 4 = 172 hours

172 * $4.00/hour = $688.00

 

Total Charges: $688.00

For the month, your bill will be $688.00, a total that includes $0 for training, $688.00 for inference, and complete use of the free tier.

Example 2: Finding missing components in printed circuit boards (PCBs)

Let’s say you are a printed circuit board (PCB) manufacturer. You want to check for PCBs with missing components before they are sent to the next processing stage. For simplicity, assume you need two inference units to process the number of PCBs manufactured in an 8-hour workday. Assume you’ve already used all your free tier usage for this month. The bill at the end of using Amazon Lookout for Vision for 22 days in the month (assuming you are not running the lines during the weekends that excludes eight days in the month) in US East (N. Virginia), would be calculated as follows:

Monthly training and inference hour charges

Assume you retrained your model for two training hours to improve your model performance, and you would use inference hours on a daily basis (8 hours/day x 22 days x 2 inference units) for 352 inference hours. For the 22 working days of the month, you would incur charges as detailed in the table below.

Usage type Hours used Price Number of billable hours Charge for the month 
Training 2

$2.00/hour

2 2 * $2.00/hour = $4.00
Inference tier 1 (First 300 hours) 300

300 * $4.00/hour = $1,200.00

Inference tier 2 (Next 3000 hours) 52

$3.60/hour

52

52 * $3.60/hour = $187.20

 

Total Charges: $1,391.20

For the month, your bill will be $1,391.20, a total that includes $4 for training, $1,200.00 for inference tier 1, and $187.20 for inference tier two.

Example 3: Finding surface defects in silicon wafers

Let’s say you manufacture silicon wafers on three production lines. You want to check for wafers with spots and discolorations before they are sent to the next processing stage. For simplicity, assume you need one inference unit per production line and manufacture wafers 8 hours/day. Assume you have already used all your free tier usage for this month. The bill at the end of using Amazon Lookout for Vision for 22 days in the month (assuming you are not running the lines during the weekends, that excludes 8 days in the month) in US East (N. Virginia), would be calculated as follows:

Monthly training and inference hour charges

Assume you retrained each model per production line for two training hours to improve your model performance (2 hours x 3 production lines) for six training hours, and you would use inference hours on a daily basis (8 hours/day x 22 days x 1 inference units x 3 production lines) for 528 inference hours. For the 22 working days of the month, you would incur charges as detailed in the table below.

Usage type Hours used Price Number of billable hours Charge for the month

228 * $3.60/hour = $820.80

 

Total Charges: $2,032.80

For the month, your bill will be $2,032.80, a total that includes $12 for training, $1,200.00 for inference tier 1, and $820.80 for inference tier two.
