Local AI · Local AI
The complete map of local AI: why ownership wins, what hardware actually matters, which stack to install — and the exact month your setup pays for itself.
Your prompts, your documents, your family's voice notes — processed by silicon in your house, not by a company you'll never meet. Local AI makes "we take privacy seriously" literal.
Subscriptions are forever-rentals with annual price hikes. A one-time hardware purchase runs the best open models for years, offline, at electricity cost.
Three typical subscriptions cost $600+/year. A capable used rig costs less than one year of renting — and keeps every upgrade Open-weights ship.

$0
Models up to ~8B at readable speeds (Qwen3 4B is the sweet spot), plus Whisper and image gen on Apple silicon.
+
• Zero investment • Perfect for testing the waters • Apple silicon Macs punch far above their class
−
• Slow for big models • Image gen is painful on CPU
$250–400 (used RTX 3060 12GB)
8B–14B models at Q4–Q6 with real context, SDXL image gen, Whisper, embeddings. The classic first rig.
+
• Cheapest true AI GPU • Huge second-hand market • Runs 90% of daily-driver workloads
−
• 70B-class models are out of reach • Older architecture (no FP8)
$700–1600 (used RTX 3090 → RTX 4060 Ti 16GB / 5060 Ti 16GB)
32B reasoning models, Qwen3 30B-A3B at speed, FLUX image generation, serious RAG with long context.
+
• 32B-class local reasoning • FLUX-class image gen • Used 3090 = best VRAM-per-dollar ever
−
• Used-market lottery on the 3090 • Power draw needs a decent PSU
$1400–3500 (M-series, 32–64GB unified)
70B-class models quietly on a desk, excellent Whisper/audio, decent image gen. One cable, no jet engine.
+
• Huge unified memory for LLMs • Silent and efficient • Best watts-per-token in the house
−
• Image gen slower than NVIDIA • Not upgradeable — buy the RAM you'll need
$3500+ (2× RTX 3090/4090, or 5090)
70B at Q4 comfortably, 100B+ MoEs, fine-tuning your own models, serving the whole family or office.
+
• Frontier-adjacent, fully private • Fine-tuning becomes practical • Can pay for itself hosting for others
−
• Real money and a real PSU • Heat and noise need planning

No. Ollama runs 3–4B models on any modern CPU, and Apple silicon Macs are excellent without any discrete GPU. A 12GB card is where it gets fast and serious.
For chat, writing, coding help and private RAG: 8–32B open models are genuinely competitive for daily tasks. For frontier edge cases, the biggest cloud models still win — the ROI question is whether those edge cases justify $600+/year.
Compressing the model's weights from 16-bit to ~4-bit numbers so it fits in a fraction of the VRAM, losing very little quality. Q4_K_M is the community default. See the glossary.
Yes: 3–8B models run fine on recent laptops (CPU or integrated GPU). Dedicated 8GB+ laptop GPUs unlock the comfortable tier. MacBooks with 16GB+ unified memory are the best laptops for this.
A desktop rig under mixed use adds roughly $1–3/month in most regions. The ROI calculator includes an optional conservative estimate.
