LegacyRemaster · reddit · 2026-08-01
A user shared their local deployment experience running DeepSeek-V4-Flash-0731 (Q3KXL quantized version).
- Hardware: Utilized a mixed setup with RTX 6000 (96GB) and W7800 (48GB) via llama-server.
- Performance: Successfully processed a highly complex physics simulation prompt (generating an HTML file of a breaking aquarium with realistic water flow, buoyancy, and collisions), outputting 21k tokens at an average speed of 27.2 tokens/s.
- Verdict: The author noted that the model delivers great performance at a lower cost compared to K3 and GLM 5.2.
