Free Developer Tier
The Free Developer Tier package is designed to provide you with an affordable and accessible way to use PhoenixAI services. By understanding and complying with the package's limitations, you can take advantage of PhoenixAI's benefits without incurring any charges from PhoenixAI.
The Free Developer Tier only exempts you from your CCU usage charges. You still need to pay your cloud provider for the infrastructure used to run your Free Developer Tier cluster.
Create a Free Developer Tier cluster
You are allowed to create only one Free Developer Tier cluster per account. If you already have a Free Developer Tier cluster within your PhoenixAI Cloud account, you must unlock or release it before you can create a new Free Developer Tier cluster again.
A Free Developer Tier cluster consists of the following components:
- One FE
- Up to 4 CPU cores
- Up to 16 GB RAM
- One CN
- Up to 4 CPU cores
- Up to 16 GB RAM

Scaling restrictions
Scaling is not allowed in Free Developer Tier clusters.
You must first unlock your Free Developer Tier cluster before you can scale it. Once unlocked, your Free Developer Tier cluster will be treated as a regular cluster and charged at the published fee rate.
When you attempt to scale your Free Developer Tier cluster, PhoenixAI prompts you to unlock the cluster before you can continue. For more information, see Scale a PhoenixAI cluster.
Billing concerns
A Free Developer Tier cluster is not included in the billing process, and its CCU consumption will always be 0. As such, no CCU charges will ever be incurred while you are using your Free Developer Tier cluster. You still need to pay your cloud provider for the infrastructure used to run your Free Developer Tier cluster.
