Which local LLMs fit on an A100 (80GB HBM2e)?

The A100 has 80GB HBM2e of discrete VRAM. After a 2 GiB reserve for the OS and display, about 78 GiB is usable for a model. At an 8K context the largest model in our list that fits is gpt-oss-120b at MXFP4 (about 62.8 GiB).

These are estimates from the model's config and file sizes, not measurements. How we calculate

Which models fit at 8K

Each model uses the highest-precision file that fits, one chat at a time.

Detailed checks

Can Qwen2.5-72B-Instruct run on A100?

Memory

NVIDIAA100 80GB SXM HBM2e
Memory kindDiscrete VRAM
Marketed80GB HBM2e
Gross80.00 GiB (85,899,345,920 bytes)
Default reserve2.00 GiB (2,147,483,648 bytes)
Net budget78.00 GiB (83,751,862,272 bytes)

The reserve is an adjustable assumption. On a headless machine you can lower it in the calculator.

Two of these cards do not add up to one bigger card. Each copy of a model has to fit on one card unless the engine splits it with tensor parallelism.
