Frequently asked questions

Can GPT-OSS 120B (MoE) run on Intel Gaudi 3 128GB?

Yes. GPT-OSS 120B (MoE) at AWQ 4-bit needs 66.7 GB including the KV cache, and Intel Gaudi 3 128GB has 128 GB — so it fits on a single GPU.

How fast is GPT-OSS 120B (MoE) on Intel Gaudi 3 128GB?

672.9 tokens/sec per stream and 8075 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 122.6 ms, and inter-token latency is 1.5 ms.

What does GPT-OSS 120B (MoE) on Intel Gaudi 3 128GB cost per million tokens?

$0.0688 per 1M output tokens at 1× Intel Gaudi 3 128GB ($2.00/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.

How much VRAM does GPT-OSS 120B (MoE) need on Intel Gaudi 3 128GB?

64.3 GB for the weights at AWQ 4-bit, plus 2.5 GB of KV cache for 8 concurrent requests at 8K context — 66.7 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is Intel Gaudi 3 128GB the right choice for GPT-OSS 120B (MoE)?

It works. Compare $0.0688 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 8× RTX 3080 10GB at $0.004393, and the fastest is 2× Cerebras CS-3 (WSE-3) at 166400 tok/s.
