Solar Open 2 (Upstage) is a 250.0B parameters MoE (15.0B active per token) open-weight model tracked on AI Hashrate. At 8K context we estimate roughly 138.88 GB VRAM for Q4 (weights 137.5 GB + KV 0.38 GB + 1 GB overhead) and 501.38 GB for FP16. About 5 GPUs/accelerators in our catalog fully fit this model at Q4 under that context assumption. Fastest Q4 configs: B200 192GB SXM ≈ 510.3 tok/s (estimated); MI300X 192GB ≈ 333.6 tok/s (estimated); H200 141GB SXM5 ≈ 306.2 tok/s (estimated); DGX Spark (GH200 480GB) ≈ 30.9 tok/s (estimated); Mac Studio M2 Ultra 192GB ≈ 30.0 tok/s (estimated). Use the table below for VRAM fit and tok/s per dollar (list MSRP). Estimates follow memory-bandwidth math; measured rows override when present. See methodology for details. Methodology.
