Do Vultr referral credits expire?

Referral credits are subject to Vultr's official program terms, which may include expiration policies. Please review Vultr's current terms at vultr.com for the most accurate and up-to-date information on credit validity.

Is this site affiliated with Vultr Inc.?

No. This website is independently operated and is NOT affiliated with, endorsed by, or officially partnered with Vultr Inc. We are an independent resource that uses Vultr's public referral program.

Can referral credits be withdrawn as cash?

No. Vultr referral credits are account credits applicable toward Vultr services only. They cannot be withdrawn as cash or transferred to other accounts.

What happens if I don't use the referral link?

If you sign up for Vultr without using the referral link, no referral credits will be applied. The referral code must be embedded in the signup URL for tracking purposes.

Are GPU servers good for AI startups?

Yes. Cloud GPU servers are ideal for AI startups because they eliminate the massive upfront capital cost of GPU hardware, allow instant scaling, and provide access to enterprise-grade NVIDIA GPUs (A100, H100) on demand.

What GPU VRAM do I need to run a 70B LLM?

A 70B parameter model in FP16 requires approximately 140GB of VRAM. In practice, you'd need either multiple A100 80GB GPUs or a single H100 NVL configuration. Quantization (GGUF, AWQ, GPTQ) can reduce this to 35-45GB at 4-bit precision.

Can I run Stable Diffusion on a cloud GPU?

Absolutely. Stable Diffusion XL runs efficiently on GPUs with 16GB+ VRAM. Cloud GPU instances are excellent for batch image generation, running ComfyUI workflows, and serving image generation APIs at scale.

Data Center GPUs

Designed for 24/7 compute workloads, data center GPUs like the NVIDIA A100 and H100 offer ECC memory, NVLink connectivity, and Tensor Core acceleration purpose-built for AI training and inference.

Consumer GPUs

Consumer GPUs (RTX series) offer excellent price-to-performance for development, testing, and smaller model inference. Ideal for prototyping before scaling to data center hardware.

VRAM Matters for LLMs

A 7B parameter model requires ~14GB VRAM in FP16. A 70B model needs ~140GB. Larger VRAM enables bigger models, longer context windows, and larger batch sizes for throughput.

Bare Metal vs Virtualized

Bare metal GPU instances give you direct hardware access with no hypervisor overhead — critical for maximum training throughput. Virtualized GPUs offer flexibility at slightly lower peak performance.
