Frequently asked questions

Can Multilingual E5 Large (1024-dim) run on Cerebras CS-3 (WSE-3)?

Yes. Multilingual E5 Large (1024-dim) at FP16 needs 7.6 GB including the KV cache, and Cerebras CS-3 (WSE-3) has 44 GB — so it fits on a single GPU.

How fast is Multilingual E5 Large (1024-dim) on Cerebras CS-3 (WSE-3)?

11607 tokens/sec per stream and 139286 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 44.8 ms, and inter-token latency is 86.2 µs.

What does Multilingual E5 Large (1024-dim) on Cerebras CS-3 (WSE-3) cost per million tokens?

— per 1M output tokens at 1× Cerebras CS-3 (WSE-3). 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 Cerebras CS-3 (WSE-3)?

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 Cerebras CS-3 (WSE-3) 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.
