Pricing & availability
How this list works
The two views
By provider shows one card per company, placed where its best offer ranked. By configuration lists every offer.
Order
What you can rent comes first: in stock, then waitlist, then not reported, then out of stock. Priced offers rank ahead of quote-only, and on-demand ahead of other billing types.
Within a group, five factors set the order:
- Location: datacenter proximity, blended with provider HQ.
- Price: hourly price, per GPU and in total.
- Billing type: reserved ahead of spot, spot ahead of quote-only.
- Specs: more VRAM, vCPUs and RAM.
- Provider diversity: a provider's repeat rows rank slightly lower, so one company can't take all the top spots.
Search
We match the provider, its country, GPU model, form factor, billing type, availability and instance name. Matching is partial and case-insensitive. Everyday words work too, so "interruptible" finds spot and "sold out" finds out of stock.
Transparency and funding
- Ads and sponsors: Paid placements sit at the top of the list and are always labeled as sponsored content. Sponsorship never influences the organic ranking itself.
- Affiliates: Affiliate links are marked. We may earn a commission if you click them, but commissions never affect the order.
- Prices: Shown in USD, converted at daily reference rates where a provider publishes in another currency. A month means 720 hours. How we estimate costs.
Heads up: A provider's own page may quote a different figure, for example on tax, region or a promotion. A monthly-only plan shows a derived hourly rate. Verify before provisioning. More on how we price.
What can the A4000 run?
One A4000 has 16 GB of VRAM. In practice, that's enough memory for roughly 8B parameters at 4-bit or 2B at 16-bit, assuming a 32K context. Below are some open-weight LLMs, with the estimated memory and GPUs each one needs.

Estimates based on the median on-demand rate. Memory is weights plus FP16/BF16 KV cache at 32K context per request. GPU counts assume 90% of advertised VRAM is usable. No guarantee of runtime support, usable performance, or that a matching quantized build exists. How we estimate costs.

No median for spot: we only show this when at least 3 providers list the GPU on that billing type. 1 provider also quotes the A4000 on a custom contract, priced per deal.
Who has the cheapest A4000?
How much does the A4000 cost per month?
-
At 720 hours per month, one A4000 costs an estimated $137 at the median on-demand price. Cheapest verified in stock: $50 per month on-demand, $36 reserved (3 mo), $43 spot.
Where can I rent an A4000?
-
GetDeploying currently tracks A4000 configs from 13 providers. The cheapest verified in-stock on-demand configs come from Vast.ai, GPU.ai, Spheron and Sesterce. See the full price comparison above for every provider and config.
Are A4000 prices going up or down?
-
As of September 13, 2026, the median on-demand price has been flat over the past 90 days, at about $0.19 per GPU per hour.
How many A4000 GPUs do I need?
-
One A4000 runs models up to roughly 8B parameters at 4-bit quantization or 2B at 16-bit, assuming a 32K context. Larger models run across multiple GPUs: the model table above shows the estimated memory and GPU count for popular open-weight LLMs.
Why choose the A4000?
-
16GB GDDR6, compact single-slot professional GPU. Low power consumption. Suitable for entry-level AI development and visualization.
When is the A4000 not a good fit?
-
No NVLink. 16GB VRAM limits model sizes. For dedicated cloud AI inference, the L4 offers better throughput at lower cost.
