To enhance performance and offer more flexible pricing options, we will implement a new pricing policy effective June 10, 2025 (KST). This update will offer a wider range of pricing plans to suit your needs, and we will do our best to provide all necessary guidance to ensure a smooth transition.
Summary of Key Changes
What is an Atom?
Atom is the unit of credit used to run simulations on Materials Square.
1 Atom = $1
1 Core-hour (Spot) = 0.25 Atom
1 Core-hour (On-Demand) = 0.5 Atom
For example, with 1 Atom, you can run 2 core-hours on On-Demand (4 core-hours on Spot).
[1] Atom Pack
Atom Pack is a bulk credit package that allows users to purchase large quantities of Atoms at a discounted price, with selectable validity periods. Atoms can be flexibly applied to different jobs and core usages. In particular, the 1-month Atom Pack offers a cost-effective option for short-term use.
Key Points:
- Plan duration options: 1 month or 1 year (Pricing varies by selected duration)
- The previous GRAPHITE-100 plan is now replaced by Atom Pack AC (academic only)
*CH : Core Hour
*Prices shown are exclusive of VAT
[2] Spot Compute Subscription
Spot Subscription is a monthly or yearly plan that allows you to use simulation services on designated Spot Instances provided by Materials Square. Because Spot Instances utilize surplus server capacity, this option offers a more affordable pricing model.
Please note: Spot Instances can be interrupted at any time, which may stop your calculation. In such cases, calculations may need to be restarted manually.
