What Is DDS Hub? A Beginner's Guide to Using Claude, Codex and GLM AI Models

AI models are becoming an important part of modern software development.

Developers use models such as Claude, Codex, and GLM for:

Code generation
Debugging
AI coding assistants
Automation workflows
Software engineering tasks

However, accessing and managing different AI models can be complicated. Different models may require different APIs, different clients, and different configurations.

DDS Hub provides a simpler way for developers to manage AI model access through a group-based API system.

This guide explains:

What DDS Hub is
How DDS Hub works
How to create and use API keys
How model groups work
How to choose the right group for Claude, Codex, and GLM workflows

What Is DDS Hub?

DDS Hub is an AI model access platform that provides developers with access to multiple AI model ecosystems through dedicated API groups.

Instead of connecting every application directly to different AI providers, developers can configure their tools with DDS Hub's API endpoint and use the appropriate model group.

The basic workflow is:

code

Developer
↓
AI Client / Application
↓
DDS Hub API Gateway
↓
Selected Model Group
↓
AI Model

DDS Hub supports different AI workflows, including:

Claude Code development
Codex coding workflows
GLM API applications
AI automation projects

How Does DDS Hub Work?

DDS Hub uses a group-based API key system.

A common misunderstanding is that one API key can access all AI models. This is not how DDS Hub works.

Each API key belongs to a specific group. The relationship is:

code

API Key
↓
Model Group
↓
Available Models

Example 1: Claude Group

Create:

code

API Key A
↓
Claude Group

This key can access Claude models included in the Claude group. It cannot access:

Codex models
GLM models

Example 2: Codex Group

Create:

code

API Key B
↓
Codex Group

This key is used for Codex-related workflows. It cannot access:

Claude models
GLM models

This design provides better control over:

Model access
Pricing
Stability
Usage scenarios

Understanding DDS Hub Model Groups

Different users have different needs.

Some developers need stable API access.
Some prefer lower-cost options.
Some only need AI coding assistants.

DDS Hub separates these requirements into different groups.

Claude Groups

Claude models are widely used for:

AI coding
Software architecture
Debugging
Long-context reasoning

DDS Hub provides different Claude-related groups.

Group	Access Method	Features	Best For
Claude Max Pool Group	Claude Code CLI only	Optimized for Claude Code usage	Individual developers
Claude Stable Group	API access	Higher stability	Development and production
Claude Discount Group	API access	Lower cost, possible stability/cache fluctuation	Testing and lightweight workloads

Claude Max Pool Group

This group is designed for users who mainly use:

Claude Code CLI
AI programming assistants

Example workflow:

DDS Hub Claude Group
↓
Claude Models

It is suitable for developers who want a Claude Code experience.

Claude Stable Group

The stable group focuses on API-based applications. Suitable for:

SaaS products
Backend integration
Automation systems
Development environments

Claude Discount Group

The discount group focuses on cost efficiency. It is suitable for:

Experiments
Personal projects
Lightweight coding tasks

Because it focuses on lower cost, users may experience:

Availability changes
Cache differences
Performance fluctuations

Codex Groups

Codex is designed for coding-focused workflows. DDS Hub provides multiple Codex access methods.

Group	Access Method	Best For
Codex Basic Group	Codex Client	Standard Codex usage
Codex CC Group	Claude Code integration	AI coding workflows
Codex External Group	API access	Applications and automation

Codex Basic Group

Designed for users who mainly work with Codex clients. Typical use cases:

Code generation
Programming assistance
Daily development

Codex CC Group

This group allows developers to use Codex capabilities inside Claude Code workflows. Useful for users who want:

Claude Code interface
Codex model capability

Codex External Group

Designed for API integration. Suitable for:

Software products
Developer tools
Automated coding systems

GLM Groups

GLM models are popular for cost-efficient AI applications. DDS Hub provides:

Group	Protocol	Usage
GLM Group	OpenAI Compatible API	Application development
GLM CC Group	Claude Code compatible	AI coding

GLM OpenAI Compatible API

Developers can use standard OpenAI-compatible SDKs.

Example:

code

Suitable for:

AI applications
Backend services
Experiments

How To Use DDS Hub

The basic setup process is simple.

Step 1: Create a DDS Hub Account

Step 2: Select the Correct Group

Choose based on your usage:

Your Goal	Recommended Group
Claude Code	Claude Max / Claude CC compatible group
Claude API	Claude Stable or Discount
Codex Client	Codex Basic
Codex API	Codex External
GLM Application	GLM API

Step 3: Create an API Key

Create an API key under your selected group.

Example:

code

sk-xxxxxxxx

Remember: one API key belongs to one group.

Step 4: Configure Your Application

For Claude Code:

bash

export ANTHROPIC_AUTH_TOKEN="your_api_key"
export ANTHROPIC_BASE_URL="https://www.ddshub.cc"

For OpenAI-compatible applications, configure the DDS Hub endpoint and API key.

You can find step-by-step setup instructions in the DDS Hub documentation.

How To Choose The Right Group

Different workflows require different choices.

Personal Coding

Recommended:

Claude Max Pool
Codex Basic

Reason: simple setup and optimized for client usage.

Software Development

Recommended:

Claude Stable
Codex External
GLM API

Reason: more suitable for applications and testing.

Cost Optimization

Recommended:

Claude Discount
GLM Group

Reason: lower cost for experiments and lightweight tasks.

Why Use a Group-Based System?

A group-based architecture provides several advantages.

Better Control

Each key has clear permissions. Developers know:

Which model they are using
Which resources they access
What pricing applies

Easier Management

Teams can separate:

Development keys
Production keys
Testing environments

Flexible AI Workflow

Different tasks can use different models.

Example:

code

Complex reasoning
↓
Claude Group

Fast coding
↓
Codex Group

Cost-efficient tasks
↓
GLM Group

DDS Hub for Modern AI Development

Modern developers rarely use only one AI model. Different models have different strengths.

A practical workflow may combine:

Task	Model Type
Architecture analysis	Claude
Fast coding	Codex
Cost-efficient generation	GLM

DDS Hub allows developers to organize these workflows through different groups. You can compare the available options on the DDS Hub models page.

Conclusion

DDS Hub is a flexible AI model access platform built around a group-based API system.

Instead of managing multiple complex integrations, developers can:

Choose the right model group
Create a dedicated API key
Configure their development tools
Start using AI models

Whether you are using Claude Code, Codex workflows, or GLM applications, choosing the correct group helps balance:

Performance
Stability
Cost

Understanding the relationship between API Key → Group → Model is the first step to using DDS Hub effectively. When you're ready, activate API access on DDS Hub and create your first group-based key.
