Run Qwen3 1.7B on a VPS.
September 2026 · 242 of 280 plans fit · re-ranked daily
Small model with a thinking mode; strong for its size on structured output. On a CPU-only VPS it needs about 3.7 GB of RAM: 1.3 GB of Q4_K_M weights, 922 MB of KV cache for an 8,192-token context and 1.5 GB for the OS and runtime. 242 of the 280 plans in our index fit; the cheapest comfortable pick is Contabo's Cloud VPS 4 · 4 vCPU · 8 GB at $6.39/mo, streaming an estimated 7.8–16 tok/s.

Speed = effective memory bandwidth ÷ active weight bytes (4 GB/s per shared vCPU, 6 per dedicated), shown as a band. Real numbers depend on the host CPU generation, AVX-512/AMX support and how noisy the neighbours are — treat these as order-of-magnitude.

Break-even
The Raspberry Pi 5 (16 GB) pays for itself after 50 months of replacing the VPS — and it streams an estimated 3.6–5.6 tok/s against the VPS's CPU-only pace.
* approximate: August 2026 US retail median rather than list price. Local speed = peak bandwidth × 0.7 efficiency (0.35 on CPU-only boards) ÷ active weight bytes; unified-memory machines are assumed to give models 75% of their RAM. GPU cards need a host PC that is not included in the price.
Frequently asked
- How much RAM does Qwen3 1.7B need?
- About 3.7 GB for CPU inference at Q4_K_M: 1.3 GB of weights, 922 MB of KV cache at 8,192 tokens of context, and 1.5 GB of headroom. Longer contexts need more KV cache (112 KB per token for this model).
- What is the cheapest VPS that can run Qwen3 1.7B?
- Contabo Cloud VPS 4 · 4 vCPU · 8 GB (8 GB RAM, 4 vCPU) at $6.39/mo excl. VAT runs it comfortably as of 5 Sept 2026. OVHcloud VPS-1 2027 · 2 vCPU / 4 GB at $5.35/mo is a tight fit.
- How fast will Qwen3 1.7B run on a VPS without a GPU?
- Roughly 12–23 tok/s on the top pick. Token generation is bound by memory bandwidth — each token streams the full weights once — so more and dedicated vCPUs help; a GPU or Apple-silicon machine is 10–50× faster.
