CoCo AI (Coding Assistant)
CoCo AI is our AI-assisted coding service, utilizing Chat AI and is accessible via your SAIA API key. It brings large language models directly into your development environment for code suggestions, chat-based assistance, and autonomous multi-step coding tasks.
Getting Started
Before configuring any tool, you need:
- A SAIA API key. If you don’t have one yet, request one here.
- A supported editor or terminal. See the sections below.
- A model to use. Browse the available models. We recommend starting with
qwen3-coder-30b-a3b-instructordevstral-2-123b-instruct-2512for coding tasks.
Info
Only models hosted on GWDG’s HPC infrastructure (internal models) are available via the API. External models (e.g., GPT-4, Claude) are accessible through the Chat AI web interface only and cannot be used with CoCo AI.
Code Completion vs. Agentic Coding
CoCo AI supports two categories of AI-assisted development:
| Code Completion | Agentic Coding | |
|---|---|---|
| What it does | Inline suggestions as you type, plus chat for explaining or editing code | Autonomous multi-step tasks: reading your codebase, editing files, running commands |
| Level of autonomy | You drive; the model suggests | The model drives; you review and approve |
| Best for | Writing code faster, understanding unfamiliar code, quick edits | Refactoring across files, generating tests, scaffolding projects |
Not sure which to start with? Code completion is the simpler entry point. If you find yourself describing multi-step plans in the chat, consider switching to an agentic tool.
