For each model, the highest-precision quantization that runs entirely in fast memory; otherwise the one with the best result. Speeds are ranges; "estimate" unless a benchmark exists for this exact hardware.

Limits in plain words
80 GB of VRAM holds the weights and KV cache of models up to about gpt-oss-120b at Q4_K_M. Bigger models spill into system RAM and slow down sharply: generation speed is then limited by RAM bandwidth, not by the GPU.
Frequently asked questions
Which LLMs can the A100 80GB run?
Entirely on the GPU: gpt-oss-120b (MXFP4), Llama 4 Scout 17B-16E Instruct (Q4_K_M), Qwen2.5 72B Instruct (Q6_K), Llama 3.3 70B Instruct (Q6_K), DeepSeek R1 Distill Llama 70B (Q6_K), Mixtral 8x7B Instruct (Q8_0), Qwen3 32B (Q8_0), DeepSeek R1 Distill Qwen 32B (Q8_0). Larger models need CPU/GPU offload.
Can the A100 80GB run a 70B model?
Excellent: a 70B model at Q4_K_M needs about 45.1 GB; the A100 80GB has 80 GB.
How is the speed estimated?
Token generation reads every active weight once per token, so it is limited by memory bandwidth (1935 GB/s here). We apply an efficiency range per backend and label the result as an estimate until real benchmarks exist.
