Overview
This chapter documents the AI inference, voice processing, and workflow automation services running on Centerpoint. All GPU-accelerated workloads leverage an NVIDIA GeForce RTX 5080 connected to the Mini PC via OcuLink, providing 16 GB of GDDR7 VRAM on the Blackwell architecture (Compute Capability 12.0).
GPU Hardware
| Property | Value |
|---|---|
| GPU | NVIDIA GeForce RTX 5080 |
| VRAM | 16 GB GDDR7 (16,303 MiB) |
| Architecture | Blackwell (Compute Capability 12.0) |
| Connection | OcuLink (external GPU enclosure) |
| NVIDIA Driver | 580.159.03 |
| CUDA Version | 12.9 |
| Container Runtime | nvidia (all GPU containers) |
All containers that use the GPU are launched with runtime: nvidia and
NVIDIA_VISIBLE_DEVICES=all. No device passthrough via --device /dev/dri is
used — the Intel Arc / IPEX-LLM path has been retired.

Compose Project
Most AI stack services (Ollama, Open Web UI, Kokoro, Faster-Whisper, Open Notebook,
Riffado) are managed as a single Portainer compose project called ai-stack on
a shared ai-internal bridge network plus traefik-net. N8N, PaperlessAI, and
MCP GitHub are separate Portainer stacks.
