GLM 5.3 hardware requirements and cost
Even at 4-bit it needs about 520 GB (4× H200 (564 GB)), well beyond a home workstation, so most people run it on rented multi-GPU servers. Full BF16 precision needs about 1.7 TB (Multiple nodes (over 1.1 TB)).
| Precision | Weights | With headroom | Smallest setup |
|---|---|---|---|
| BF16 (full precision) | 1.5 TB | 1.7 TB | Multiple nodes (over 1.1 TB) |
| FP8 / 8-bit | 753 GB | 866 GB | 8× H200 (1,128 GB) |
| 4-bit (GGUF Q4_K_M) | 452 GB | 520 GB | 4× H200 (564 GB) |
Estimate: parameters × bytes per parameter, plus 15% for the KV cache and runtime at modest context lengths. Long contexts and large batches need more.

Scores are published results from model cards, lab reports, and public leaderboards, each linked to its source. Settings such as thinking mode or test version differ between sources and are shown next to each score. OpenLLM Buddy catalog models are uncensored fine-tunes; their scores are those of the official base model. Data collected 2026-10-30. How the index works
