Frequently asked
- Can A100 80GB run Mixtral-8x7B-v0.1?
- Not at fp16 — Mixtral-8x7B-v0.1 needs about 95.3 GB while A100 80GB has 80 GB. It fits at INT4 quantization (25.6 GB) with some accuracy trade-off. For full precision, use H200 instead.
- How much VRAM does Mixtral-8x7B-v0.1 use?
- About 95.3 GB at fp16, 25.6 GB at INT4 (for a 4K context, batch size 1). Longer contexts add to KV cache size; larger batches increase activations.
- What's the fastest way to run Mixtral-8x7B-v0.1 on A100 80GB?
- Use a production inference engine like vLLM, SGLang, or TensorRT-LLM with paged attention — they cut KV cache 2–3× vs the naive estimate and batch multiple requests efficiently. For A100 80GB, enable Flash Attention 2.
- Where can I rent a A100 80GB?
- GPUniq aggregates live A100 80GB offers from verified providers. You can deploy an instance in about a minute and pay hourly with no commitment.
