A Reddit user demonstrated DeepSeek V4.1 Flash running at 1M context on consumer hardware — an RX 9070 XT 16 GB, 5800X3D, 64 GB DDR4, and PCIe 3.0 NVMe — achieving 20× faster agent session startup via a patched Strata implementation. The setup counters Sam Altman's criticism of distributed DRAM utilization by fully saturating local memory. The optimization enables high-context inference on standard gaming GPUs without datacenter infrastructure.
