Deploy with Sealos

Multi-Model Support

FastGPT uses the one-api project to manage model pools, supporting OpenAI, Azure, mainstream domestic models, and local models.

See: Quick OneAPI Deployment on Sealos

With Sealos, you don't need to purchase servers or domains. It supports high concurrency and dynamic scaling, and databases use KubeBlocks with far better I/O performance than simple Docker container deployments. Choose a region below based on your needs.

Singapore Region

Singapore servers are overseas with direct access to OpenAI, but users in mainland China need a VPN. International pricing is slightly higher. Click below to deploy 👇

Beijing Region

The Beijing region is hosted by Volcano Engine. Users in mainland China get stable access, but it can't reach OpenAI or other overseas services. Pricing is about 1/4 of the Singapore region. Click below to deploy 👇

1. Start Deployment

Since databases need to be deployed, wait 2–4 minutes after deployment before accessing. The default uses minimal resources, so the first access may be slow.

Follow the prompts to enter root_password and the openai/oneapi address and key.

After clicking deploy, you'll be redirected to the app management page. Click the details button on the right side of the fastgpt main app (named fastgpt-xxxx), as shown below.

After clicking details, you'll see the FastGPT deployment management page. Click the link in the external access address to open the FastGPT service.

To bind a custom domain or modify deployment parameters, click Change in the top right and follow Sealos' instructions.

2. Log In

Username: root

Password: the root_password you set during one-click deployment

How to Update/Upgrade FastGPT

Upgrade script documentation — read the docs first to determine which version to upgrade to. Do not skip versions.

For example, if you're on version 4.5 and want to upgrade to 4.5.1: change the image version to v4.5.1, run the upgrade script, wait for completion, then continue upgrading. If the target version doesn't require initialization, skip it.

Upgrade steps:

Check the update documentation to confirm the target version — avoid skipping versions.
Open Sealos app management
There are 2 apps: fastgpt, fastgpt-pro
Click the 3 dots on the right side of the app, then Change. Or click details, then Change in the top right.
Modify the image version number

Click Change/Restart to automatically pull the latest image and update
Run the initialization script for the corresponding version (if applicable)

How to Get the FastGPT Access Link
