Frequently asked questions

Can GTE Large (1024-dim) run on A100 80GB SXM4?

Yes. GTE Large (1024-dim) at FP16 needs 7.3 GB including the KV cache, and A100 80GB SXM4 has 80 GB — so it fits on a single GPU.

How fast is GTE Large (1024-dim) on A100 80GB SXM4?

1477 tokens/sec per stream and 17727 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 76.9 ms, and inter-token latency is 676.9 µs.

What does GTE Large (1024-dim) on A100 80GB SXM4 cost per million tokens?

$0.0188 per 1M output tokens at 1× A100 80GB SXM4 ($1.20/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.

How much VRAM does GTE Large (1024-dim) need on A100 80GB SXM4?

0.9 GB for the weights at FP16, plus 6.4 GB of KV cache for 8 concurrent requests at 8K context — 7.3 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is A100 80GB SXM4 the right choice for GTE Large (1024-dim)?

It works. Compare $0.0188 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 1× RTX 3080 10GB at $0.008247, and the fastest is 1× Cerebras CS-3 (WSE-3) at 177273 tok/s.
