Four ways to run local AI inference, side by side: a plug-and-play Lucebox, cloud APIs, an NVIDIA DGX Spark, and a Mac Studio. Cost, setup, throughput, privacy, and support, no spin.
| What | Lucebox | Cloud API | DGX Spark | Mac Studio |
|---|---|---|---|---|
| Upfront cost | $5,999 | $0 | $6,500 | $11,999 with 256 GB |
| Ongoing cost | Electricity only | Per token, forever | Electricity only | Electricity only |
| 27B decode (Qwen3.8-27B) | 61.3 tok/s | Varies | 36.59 tok/s (reported) | 56.4 tok/s on M5 Max (reported) |
| Setup | Plug in, pair, go | API key | Manual | Manual |
| Privacy | Fully local | Data leaves | Fully local | Fully local |
| Tuned engine | Lucebox engine, pre-tuned | n/a | Stock | Stock |
| Memory | 32 GB VRAM + up to 192 GB unified | n/a | 128 GB unified | up to 512 GB unified |
| Support / warranty | 1-year, parts & labor | SLA | Vendor | Apple |
| Open source | Yes | No | Partial | No |
Cloud APIs have zero upfront cost and infinite scale, which is the right call for spiky or low-volume work. The trade is that the meter never stops and your prompts and data leave your machine. For a steady workload, a one-time $5,999 Lucebox is several times cheaper over two years, and nothing ever leaves the box.
On DeepSeek V4 Flash, Lucebox decodes at 86 tokens per second, over 2× the 35.3 reported for a DGX Spark and the 39.35 reported for an M5 Max. On Qwen3.8-27B, one user’s long-prompt run reached 61.3, against 36.59 and 56.4 reported. The public records use their own quants and harnesses, so read them as separate results, not a controlled test. The machine pairs a Radeon AI PRO R9700 with Ryzen AI MAX+ PRO 495 unified memory and tunes the runtime to the exact silicon. Our engineering history stays public, including up to 207 tok/s in the prior CUDA reference run and 10x faster long-context prefill.
If you run local AI regularly and want it fast, private, and a fixed cost, Lucebox is the turnkey option. It starts at $5,999, and deliveries of the first Lucebox Zero 495 batch are expected in January 2027.
