Source: RunPod pricing page, Lambda instance table, and a Vast.ai on-demand offer search, all retrieved October 3, 2026. Takeaway: a like-for-like H100 SXM hour is $3.29 on RunPod Secure Cloud, $4.29 for a single Lambda GPU, and $1.60 at the cheapest Vast.ai host in that snapshot.
RunPod: Best for Developers Who Want Flexibility
RunPod sits in the sweet spot between price and reliability. Their “Secure Cloud” tier uses datacenter hardware with strong uptime guarantees. The “Community Cloud” tier lets you access consumer GPUs at prices that rival Vast.ai — but with RunPod’s dashboard and container management on top. If you’re running LLM inference, Stable Diffusion, or fine-tuning experiments and want a polished workflow, RunPod is the easiest starting point.
Vast.ai: Best When Price Is Everything
Vast.ai operates as a GPU marketplace: individuals and small data centers list their GPUs, and you rent at the host’s on-demand rate. On October 3, 2026 the lowest of 64 rentable one-GPU RTX 4090 on-demand offers was $0.29/hr, in British Columbia. That host can still go offline mid-job. For short experiments or workloads you can checkpoint easily, the low end of the board is hard to beat. For overnight training runs, the reliability risk is significant.
Lambda: Best for Research Teams and Enterprise Workloads
Lambda offers datacenter instances with a published per-GPU-hour table. On October 3, 2026 a 1× H100 SXM was $4.29 per GPU-hour before sales tax, and the 8× H100 SXM row was $3.99 per GPU-hour, which is $31.92 for the node. The same table listed an 8× A100 SXM 80 GB at $2.79 per GPU-hour ($22.32 for the node) and did not list a 1× A100 80 GB or an RTX 4090. Lambda is the choice for ML teams that need a fixed instance price and can use the SKU that is actually on the table.
Pricing Deep Dive: RunPod vs Vast.ai vs Lambda Labs
On October 3, 2026 RunPod listed the H100 SXM at $2.69 per GPU-hour on Community Cloud and $3.29 per GPU-hour on Secure Cloud. The same day’s Vast.ai search — rentable, one GPU, on-demand, no reliability filter — returned 10 H100 SXM offers. The lowest total was $1.60/hr in France (raw $1.6037) and the median was $2.06/hr. Two of the ten were in the US or Canada; the lower of that pair was $2.67/hr. Lambda’s 1× and 8× H100 SXM rates are the $4.29 and $3.99 figures above, before tax.

Who Should Use Each Platform?
Choose RunPod if you want a balance of price and reliability with a great developer experience. Choose Vast.ai if you’re budget-constrained and willing to tolerate some uptime variability. Choose Lambda if you need a published instance price for production ML workloads and the SKU you need is on the current table.
Billing Models: What You Actually Pay
RunPod’s pricing page shows the same GPU rate per hour and per second. A 4-minute job on a Secure Cloud H100 SXM at $3.29 per GPU-hour costs $0.22. That is $3.29 × 4/60, rounded half-up to the cent. Lambda’s billing documentation says On-Demand Cloud instances are priced by hourly usage and billed in one-minute increments, from the health check after launch until you terminate the instance. The same 4-minute job on a 1× H100 SXM at $4.29 per GPU-hour costs $0.29, computed the same way.
Vast.ai on-demand rates are whatever hosts list. The October 3, 2026 search for one rentable A100 SXM4 with at least 70,000 MB of GPU memory returned 9 offers. The lowest was $0.66/hr in Germany and the median was $1.10/hr. Three were in the US or Canada, with a floor of $1.01/hr. RunPod listed the A100 SXM 80 GB at $1.39 per GPU-hour on Community Cloud and $1.59 on Secure Cloud. The A100 PCIe 80 GB row was lower: $1.19 Community and $1.39 Secure. A separate Vast.ai search for one A100 PCIe with the same memory floor returned 4 offers, lowest $0.94/hr. These marketplace figures are a snapshot, not a rate card.
Storage and Networking Costs to Factor In
As of October 3, 2026, RunPod’s pricing page lists Network Storage (Standard) at $0.07/GB/month under 1 TB and $0.05/GB/month over 1 TB. A 200 GB repository on the under-1-TB rate costs $14.00 per month while the volume exists, including when no GPU is running ($0.07 × 200). High-performance network storage on the same page is $0.14/GB/month. Lambda bills filesystems per GiB-month. The billing page’s worked example is labeled as an illustration, not the current rate; the rate is shown when you create the filesystem. The 1× H100 SXM instance row includes 2.75 TiB of SSD with the instance.
For teams running production inference endpoints that need to load multi-gigabyte models quickly, RunPod’s persistent volume that stays mounted across pod restarts is a significant practical advantage over Vast.ai’s ephemeral-first model. For single-session training jobs where you export checkpoints to S3 or similar, Vast.ai’s simplicity is adequate.
H200 and B200 Availability in 2026
As of October 3, 2026, RunPod listed the H200 at $3.59 per GPU-hour on Community Cloud and $4.59 on Secure Cloud, with 141 GB of VRAM on that page, and the B200 at $5.98 on Community Cloud and $6.79 on Secure Cloud. Lambda’s public instance table that day did not list an H200 on-demand price. It did list B200 SXM6 at $6.69 per GPU-hour on the 8× instance and $6.99 on the 1× instance, before tax. The Vast.ai snapshot included 4 rentable one-GPU H200 on-demand offers, lowest $3.56/hr in Georgia, US, and 4 rentable one-GPU B200 offers, lowest $6.25/hr in Oregon, US.
