Frequently asked questions

Can Multilingual E5 Large (1024-dim) run on Mac M2 Ultra (192GB)?

Yes. Multilingual E5 Large (1024-dim) at FP16 needs 7.6 GB including the KV cache, and Mac M2 Ultra (192GB) has 192 GB — so it fits on a single GPU.

How fast is Multilingual E5 Large (1024-dim) on Mac M2 Ultra (192GB)?

464.3 tokens/sec per stream and 5571 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 711.8 ms, and inter-token latency is 2.2 ms.

What does Multilingual E5 Large (1024-dim) on Mac M2 Ultra (192GB) cost per million tokens?

— per 1M output tokens at 1× Mac M2 Ultra (192GB). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.

How much VRAM does Multilingual E5 Large (1024-dim) need on Mac M2 Ultra (192GB)?

1.1 GB for the weights at FP16, plus 6.4 GB of KV cache for 8 concurrent requests at 8K context — 7.6 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is Mac M2 Ultra (192GB) the right choice for Multilingual E5 Large (1024-dim)?

It works. Compare — per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 1× RTX 3080 10GB at $0.0105, and the fastest is 1× Cerebras CS-3 (WSE-3) at 139286 tok/s.
