GTE Large (1024-dim) at FP16 needs 0.9 GB for its weights and 7.3 GB in total at 8K context with 8 concurrent users. That means it fits on a single RTX A4000 16GB. Every figure is computed by tokcalc's open-source capacity model.

Yes. GTE Large (1024-dim) at FP16 needs 7.3 GB including the KV cache, and RTX A4000 16GB has 16 GB — so it fits on a single GPU.
330.9 tokens/sec per stream and 3971 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 772.4 ms, and inter-token latency is 3.0 ms.
$0.0210 per 1M output tokens at 1× RTX A4000 16GB ($0.3000/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.
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.
It works. Compare $0.0210 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.
