• 2026-10-21 (~3:00 AM ET, MSN syndication — https://www.msn.com/en-us/technology/artificial-intelligence/deepseek-open-sources-its-inference-engine-withholds-cost-saving-components/ar-AA2fHRpt): DeepInfer open-sourced for V4.1-Flash under Apache 2.0, with cost-saving components withheld; earlier coverage of the release centered on the open-sourcing act and performance stats, the withholding is the new delta. Flanks the efficient-tier record (Sep 19: V4.1-Flash architecture cutting GPU memory for agent sessions 75%, ~4× concurrent sessions per GPU) — whether the withheld parts are what backs those architecture claims is not established in the coverage. Watch: which components are withheld and any DeepSeek statement on why, whether the open code reproduces the published serving performance, and whether independent hosting of V4.1-Flash inference emerges.
