Prices verified June 19, 2026. Vast.ai prices are marketplace medians and fluctuate constantly — your mileage will vary by region and host.
RunPod is what we reach for when we actually need work to get done. The pricing is higher than Vast — there's no avoiding that — but the things you get in exchange matter for real workloads.
Use RunPod when:
Where RunPod stings: the price. A100 80GB at $1.49/hr is roughly 2x what Vast can offer. Over a month of heavy usage that's a real number.
Our pod: A100 SXM 80GB, US-KS-2, $1.49/hr, 150GB Network Volume. Running months without unplanned restart. Used for daily Wan 2.2 video generation, ComfyUI workflows, and Flux fine-tuning.
Start with RunPod See real pricingVast.ai is a marketplace. Anyone with a GPU and an internet connection can list it for rent. That's the source of both its big advantage (cheap) and its big disadvantage (inconsistent). It's not strictly worse than RunPod — it's a different shape, and for some workloads it's the right shape.
Use Vast.ai when:
Where Vast stings: no persistent storage worth speaking of. Bandwidth often billed separately. Host quality is a roll of the dice — we've had instances die 4 hours in. Support is mostly community-driven.

The honest math: Vast looks cheaper, but factor in your hourly rate. If a Vast eviction costs you 30 minutes of rebuild time and you bill $100/hour for your work, you just paid $50 in time to save $0.50 in GPU cost. The math only works if the workload is fully unattended and resumable.
This is the section that should drive most of your decision. The price difference is real, but the reliability difference is bigger.
RunPod Secure Cloud uses actual data-center hardware in actual data centers. The machines are owned, racked, and monitored by RunPod or their hosting partners. The hardware is the same kind that hyperscalers use — A100 SXM nodes with NVLink, redundant power, redundant networking, the works.
We've run a single A100 SXM 80GB pod on RunPod US-KS-2 for months at $1.49/hr. In that entire window we've had:
That's the bar. For production work, for client deliverables, for anything where "the job got killed at 2am and now we're behind" is a real cost — RunPod is the answer.
RunPod's Community Cloud is a different beast. That's host-provided hardware, similar in shape to Vast. Cheaper, less consistent. Fine for short jobs, not what we'd build a service on.
Vast.ai is fundamentally a marketplace. The hardware is owned by hosts — individuals, small companies, mining operations rotating into AI, sometimes legitimate data centers. The quality distribution is wide. The platform exposes a reliability score per host (a percentage based on historical uptime) but it's a lagging indicator. A host can have 99% historical uptime and still kick you off tomorrow because their landlord cut the power.
In our experience across dozens of Vast rentals:
If you're checkpointing every 10 minutes and your jobs are resumable, that's an acceptable failure rate at half the cost. If you're running a stateful interactive session or an exposed service, it's catastrophic.
If you do go Vast, here's how to skew the odds:
If we had to pick one thing that separates RunPod from Vast, it's this. Storage is the difference between "GPU rental is an annoying chore" and "GPU rental is part of my workflow."
RunPod offers Network Volumes — block storage that lives independently of your pods. You can mount the same volume to any pod you spin up, in any compatible region. They're billed by GB-month (roughly $0.10/GB/month, with some variance by region) and they persist whether or not you have a pod running.
Our setup: a 150GB Network Volume in US-KS-2 that contains:
Cost: about $15/month for the volume. Time saved: 30-45 minutes of re-downloading checkpoints every time we spin a fresh pod. We spin pods on/off as needed; the volume just stays put.
This single feature changes how you think about GPU rental. You stop treating the pod as "my workspace" and start treating the volume as "my workspace, the pod is just the compute attached to it."
Vast has no equivalent. Storage is local to whatever host you rent. When you stop, terminate, or get evicted from an instance, the data goes with it. You can request larger disk allocations on a host, but it's not portable.
Workarounds:
None of these match the workflow of "mount a volume, work, unmount, come back tomorrow."
If you do nothing else differently: use RunPod's Network Volumes. The $10-20/month they cost will save you hours per week. We learned this the hard way after spending an entire afternoon re-downloading checkpoints to a Vast host that then died overnight.
How fast can you go from "I want a GPU" to "I'm running code on it"? Both platforms are faster than they used to be, but they have different characteristics.
The RunPod Network Volume workflow side-steps the second-cold-start problem entirely. The volume is already mounted; the models are already there; the pod boots and you're working.
RunPod includes inbound and outbound bandwidth on Secure Cloud pods. We've moved hundreds of gigabytes through our pods without seeing a bandwidth line item. Network throughput from US-KS-2 to typical destinations measures in the multiple Gbps range. Latency to common services (Hugging Face, GitHub, S3) is what you'd expect from a tier-1 data center.
RunPod also exposes proxied ports for serving HTTP from a pod (handy for running Jupyter, ComfyUI's UI, or a quick API endpoint). You get a unique URL like https://<pod-id>-8888.proxy.runpod.net without configuring anything.
Vast bills bandwidth on most hosts. The exact rate varies by host but $0.005-0.02/GB is common. For a workload that pulls 50GB of model weights at session start and uploads 5GB of generated outputs, that's $0.30-1.10 per session in bandwidth alone — not a huge number, but it adds up over many sessions.
Vast hosts vary wildly in network quality. Some are on fiber with multi-Gbps uplinks; others are on residential cable with bursty throughput. Filter listings by the host's bandwidth score if it matters to you.
Vast does let you expose ports for HTTP/SSH services, but you're working with whatever port forwarding the host has set up. There's no clean equivalent to RunPod's proxy URLs.
RunPod has a real support team. We've filed tickets and gotten responses within hours, even on weekends. The Discord is active with both staff and power users. For business-critical issues (billing, region availability, account issues), this matters.
Documentation is good — opinionated and up to date. The CLI has a Python SDK that actually works.
Vast.ai's support is more community-driven. The Discord is active and helpful, but official ticket responses are slower (sometimes 24+ hours). For a platform that's fundamentally a marketplace, this is somewhat baked into the model — when something goes wrong, it might be the host's fault, not Vast's.
Vast's documentation is comprehensive but assumes more technical knowledge. The CLI is powerful once you learn it but has a steeper curve than RunPod's tooling.
Both platforms bill cleanly and let you cap spend. Neither will surprise you with a $10K bill if you set reasonable guardrails. The Vast bandwidth line is the one item people tend to overlook.
→ RunPod. The Network Volume holds your models and ComfyUI install. Spin up, mount, work, unmount, repeat. This is literally our workflow — see our AI video generator comparison for the model side.
→ Either works. Vast saves you ~40% on the training run. If you're doing this once a month, the savings don't justify learning Vast's quirks. If you're doing 10 a week, Vast.
→ RunPod Serverless. Nothing on Vast comes close to the autoscaling model RunPod offers here.
→ RunPod Secure Cloud with reserved pricing, or a hyperscaler. Both Vast and RunPod Community can be evicted; you don't want that on day 4 of a 5-day run.
→ Vast.ai. A 3090 at $0.20/hr lets you experiment for hours on a $10 budget. Learn to checkpoint, accept some eviction risk, save money.
→ Vast. The marketplace has a wider variety of consumer GPUs, older datacenter cards, and unusual configurations.
→ RunPod, but honestly consider a managed inference platform like Replicate or a small dedicated server. GPU rental is optimized for compute, not always-on services.
→ Either. Neither platform polices the content of your jobs as long as it's legal. RunPod is the smoother experience; Vast is cheaper. See our AI image generator guide for the model side.
For transparency, here's our current GPU footprint at Null Agency as of June 2026:
Total monthly GPU spend: $200-300. For comparison, the equivalent commercial AI subscriptions (Runway Pro, Midjourney max tier, Sora Pro) would run us $400+ and still wouldn't let us run open-source uncensored models. Self-hosted on rented GPU is the move.
RunPod is the default. If you're starting from zero, sign up for RunPod, create a Network Volume, and build your workflow around it. The premium over Vast is real but small in absolute dollars, and the reliability plus persistent storage saves you more time than the money costs you.
Vast.ai is the optimization. Once you understand what your workloads look like — what's checkpointable, what's fire-and-forget, what's worth saving 40% on — start moving the right pieces to Vast. Treat Vast like spot instances on AWS: cheap when it works, replaceable when it doesn't.
The wrong move is starting on Vast because it's cheaper, having a bad eviction experience in your first week, and concluding "GPU rental is hard." It isn't. You just picked the harder platform first.
