DeepSeek-V4.1-Flash runs locally on modest hardware as users flag silent endpoint changes
Community reports show DeepSeek-V4.1-Flash running at usable speeds on single AMD MI50, 5070 Ti and multi-DGX Spark setups, while telemetry claims a provider silently swapped the API model for a -1017 variant with degraded coding behavior. Quant makers Unsloth and ISTA also published competing GGUF comparisons.

How many of you still do use DeepSeek-V4-Flash-0731 with PolyStrata/Strata or its forks because DeepSeek-V4.1-Flash-1017 is too big? - 2026-10-31 05:32 · r/LocalLLaMA

Why you can't trust cloud API endpoints: 40 days of coding-agent telemetry showing the exact day providers silently overwrote deepseek-v4.1-flash with -1017 ("faster execution, shorter answers" = 3x more swearing and 6.7x more model switches) - 2026-10-29 08:26 · r/LocalLLM
