Can the NVIDIA GeForce RTX 5090 run Orion Star (猎户星空大模型)?

Yes — here's how fast and up to what context, with real measured numbers.

Q8 yes 85k 93.4-111.4 t/s ~2.1-2.5 (slow)
Q4 yes 123k 166.9-198.9 t/s ~3.7-4.4 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.

FAQ

Can the NVIDIA GeForce RTX 5090 run Orion Star (猎户星空大模型)?

Yes. At Q4 it generates ~166.9-198.9 tok/s and fits up to 123k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~3.7-4.4 tok/s.

How much context fits?

At Q4, up to about 123k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
