Answers to the ten most common questions about running AI locally, from hardware to privacy to performance.
Q: Do I need a powerful computer to run AI locally?
Not necessarily. A modern computer with 16 GB RAM can run text-based AI (chat, code, search) on CPU at usable speeds. For image and video generation, you need a dedicated GPU with at least 6 GB VRAM. See the complete hardware guide for specific recommendations.
Q: Is local AI as good as ChatGPT or Midjourney?
For most tasks, yes. Open-source models like Llama 3.1 70B match GPT-4 on standard benchmarks. SDXL and FLUX produce images comparable to Midjourney. The gap has closed significantly in 2026. The main trade-off is that cutting-edge frontier models (GPT-5, Claude 4) are still cloud-only. Read our comparison post for detailed benchmarks.
Q: Is it really private? What data is collected?
Local-only apps and models can keep prompts, images, and files on your device when network integrations are disabled. Telemetry and other network behavior depend on product settings and the selected workflow. Current relay-assisted sync is server-assisted, not private E2EE. See our privacy architecture for the current boundary.
Q: Can I use it offline?
Absolutely. Once you have downloaded the apps and models, everything runs without internet. See 5 workflows you can run offline for practical examples.
Q: Does it work on Mac?
Yes. Thumper-Run supports macOS on Apple Silicon (M1, M2, M3, M4). Metal acceleration provides GPU-like performance for many AI tasks. Intel Macs have limited support (CPU only for most models).
Q: Does it work on AMD GPUs?
Yes, via ROCm on Linux. AMD support has improved dramatically in 2026. See our AMD GPU setup guide for supported cards and configuration.
Q: How much disk space do I need?
It depends on what you run. A typical setup:
- Thumper-Run app: ~100 MB
- One chat model (Llama 3.1 8B): ~4.5 GB
- One image model (SDXL): ~6.5 GB
- One or two apps (ComfyUI, Open WebUI): ~2 GB
- Total: ~15 GB minimum, 50 GB comfortable
The model management system helps you track and reclaim disk space.
Q: Can I use multiple AI tools at the same time?
Yes, but each GPU-accelerated tool uses VRAM. With 8 GB VRAM, you can run one tool at a time. With 16 GB+, you can run a chat model and an image generator simultaneously. Thumper-Run tracks VRAM usage and warns you before launching apps that would exceed your budget.
Q: Is it legal to run these models?
Yes. All models in the Thumper-Run catalog are released under open-source or permissive licenses (Apache 2.0, MIT, Llama Community License, CreativeML). You can use them for personal and commercial purposes. Check each model's license for specific terms.
Q: How do I update apps and models?
Thumper-Run checks for updates automatically. When an update is available, you will see a notification in the app dashboard. One click updates the app while preserving your data and settings. The platform overview describes the update mechanism.
