Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the SAVRN Index, read Sep 18, 2026.

SAVRN's Notes on Qwen3-30B-A3B-Instruct-2507

One MI300X is enough for this one. Full 16-bit weights are 61.1 GB and need 73.3 GB in memory, 8-bit lands at 36.6 GB, and 4-bit at 18.3 GB, all inside a single 192 GB card at $1.85 an hour. The 30.5B parameters are spread across 128 experts, and this is the instruct build in non-thinking mode dated July 2025. The 262,144-token context points at long documents and tool-driven agent work.

Apache 2.0 lets you run it commercially, modify it and redistribute the result, keeping the notices and stating changes. Access is open, and the 27 safetensors files total 61 GB. Before committing, read the Qwen3 technical report at arXiv:2505.09388 and decide whether you will actually fill the 262,144-token window, because 73.3 GB is weights plus overhead, not a full context. The only score in our file is 70.4 on GPQA, so test your own workload.
