An hourly GPU rate is only half of your inference cost. The other half is how many tokens you get out of each hour.
We ran four Qwen3.5 models on the same 48GB L40S, with the same settings:
- 35B-A3B (MoE): 122 tok/s
- 4B: 102 tok/s
- 9B: 61 tok/s
- 27B: 21 tok/s
Same card, same hour. The fastest model put out about 6× as many tokens as the slowest, so each of its tokens cost about a sixth as much.
The fastest one was not the smallest. The 35B-A3B is a Mixture-of-Experts model, so only a small slice of its weights runs for each token. It outpaced the 4B dense model and ran 5.8× faster than the 27B dense one. Parameter count alone did not predict speed.
Two caveats. Each number is the best of three runs per model, and the run did not record concurrency. Batching and concurrent requests change throughput per GPU, and the gaps can shift. And speed is not quality: the bigger dense models produced better output than the smaller ones, and the MoE produced the best of all four.
Our take: before you compare hourly rates, measure tok/s for your model on the card you plan to use. The rate divided by the throughput is the number that ends up on the bill.
When you size an inference deployment, what do you check first: the hourly rate or the tok/s?

1× NVIDIA L40S 48GB, Xeon Platinum 8558 (12 vCPU), 80GB RAM
vLLM 0.26, FP8, thinking off
temp 0.7, top_p 0.8, top_k 20, seeds 1/2/3; best of 3 runs per model
tok/s as shown in the video: 35B-A3B (MoE) 122, 4B 102, 9B 61, 27B 21
Single stream, one request at a time. 122 ÷ 21 ≈ 5.8.

Kimi K3.1 Pro weights are out: 2.8T total, 104B active, 1M context.
Even in MXFP4, that's far more than any single GPU can hold.
Open weights don't make it cheap to run. They let you choose where it runs.
