Frequently asked questions

Can Llama 3 8B run on TPU v6e Trillium (32GB)?

Yes. Llama 3 8B at FP16 needs 24.6 GB including the KV cache, and TPU v6e Trillium (32GB) has 32 GB — so it fits on a single GPU.

How fast is Llama 3 8B on TPU v6e Trillium (32GB)?

33.15 tokens/sec per stream and 397.8 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 346.8 ms, and inter-token latency is 30.2 ms.

What does Llama 3 8B on TPU v6e Trillium (32GB) cost per million tokens?

$0.5587 per 1M output tokens at 1× TPU v6e Trillium (32GB) ($0.8000/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.

How much VRAM does Llama 3 8B need on TPU v6e Trillium (32GB)?

16.1 GB for the weights at FP16, plus 8.6 GB of KV cache for 8 concurrent requests at 8K context — 24.6 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is TPU v6e Trillium (32GB) the right choice for Llama 3 8B?

It works. Compare $0.5587 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 4× RTX 3080 10GB at $0.0443, and the fastest is 1× Cerebras CS-3 (WSE-3) at 9714 tok/s.
