How it compares. H100 80GB HBM3: GLM-4.7-Flash 186.1 tok/s, Gemma 4 31B 76.59 (31B), Nemotron 3.5 Lightning 30B A3B 323.6 (32B), Nemotron-3-Nano-30B-A3B 316.5 (32B), Qwen3 30B A3B 283.8 (31B). 3 of 4 beat GLM-4.7-Flash here. Nemotron 3.5 Lightning 30B A3B, Nemotron-3-Nano-30B-A3B and Qwen3 30B A3B are mixture-of-experts, so per token they compute only a slice of their size.

Cost on a rented GPU. 1M generated tokens of GLM-4.7-Flash: $1.10 on a A100 40GB SXM4 ($0.47/hr, 2.3 hours), $1.39 on a RTX PRO 6000 Blackwell Workstation Edition ($1.08/hr, 77 min, 1.3x the cost).

Cheapest hourly rate we track on RunPod and Vast.ai, divided by the measured speed. Startup time and storage are extra.

Speed tiers for GLM-4.7-Flash. 30+ tok/s: 10 (RTX PRO 6000 Blackwell Workstation Edition, B300, H200). 30 tok/s is roughly where replies outpace reading.

Reading your prompt. Before GLM-4.7-Flash writes anything it reads the input: 8066.8 tok/s on the RTX PRO 6000 Blackwell Workstation Edition (0.5s for a 4,000-token prompt), 2086.0 on the L4 (1.9s). Long documents and big code files feel this number more than the generation speed.

VRAM for GLM-4.7-Flash. Measured peak 17.9GB, so 24GB is the smallest common card size; smallest card it ran on: A10G (24GB). With long context: Q4_K_M 23GB (tested), Q2_K 15GB, Q3_K_M 19GB, Q5_K_M 27GB, Q6_K 32GB.

Power on GLM-4.7-Flash. Most efficient: L4, 52W, 0.19 kWh per 1M generated tokens. Hungriest: B200, 309W, 0.47 kWh. At $0.15/kWh: $0.029 per 1M generated tokens.

Our verdict

Fastest on GLM-4.7-Flash: NVIDIA RTX PRO 6000 Blackwell Workstation Edition, 215.6 tok/s. Cheapest to rent per job: NVIDIA A100 40GB SXM4, $1.10 per 1M generated tokens.

FAQ

What GPU do I need to run GLM-4.7-Flash?

How much does it cost to run GLM-4.7-Flash in the cloud?
$1.10 per 1M generated tokens on a NVIDIA A100 40GB SXM4 at $0.47/hr, cheapest of 9 rentable cards we measured.
Can I run GLM-4.7-Flash on a 12GB, 16GB or 24GB card?
It used 17.9GB at the precision we tested. 12GB: no; 16GB: only at Q2_K (15GB); 24GB: yes.
Is the H100 80GB HBM3 or the A100 80GB SXM4 faster for GLM-4.7-Flash?
The H100 80GB HBM3: 186.1 vs 124.1 tok/s, 50% faster on our bench.

How we test

llama.cpp llama-bench at Q4_K_M, 512-token prompt and 128 generated tokens, three runs after a warmup, full GPU offload, with power and VRAM sampled throughout. Token generation is memory-bandwidth-bound, so the ranking tracks bandwidth closely, which makes it a fair guide to cards we haven't run yet.
