   Patients Bring AI Diagnoses to Doctors, Raising Safety Concerns

   Huxiu AI reports that many Chinese patients use AI to check symptoms or obtain medical advice before visiting a doctor, with a survey of 1,333 respondents finding that 69.7% had brought AI-generated advice to a consultation. The article says the viral hospital notice circulating on social media was a joke rather than a real announcement, while documenting a case in which a child received delayed evaluation because a parent relied on an AI answer. It argues that AI is more useful for organizing symptoms, medication information and questions than for making diagnoses.

   ByteDance paper finds periodic blind spots in DeepSeek V4 chunked KV-cache compression

   A ByteDance team paper, “Periodic Weak Spots: Phase Sensitivity from Chunked KV-Cache Compression,” says the chunked KV-cache compression used by the DeepSeek V4 series creates “phase sensitivity”: adding only decorative equals signs ahead of a code snippet flipped DeepSeek-V4-Flash-Base's completion between 8 and 32, with an error rate of about 71.3% when the count of equals signs modulo 4 was 0 or 1 and about 91.5% accuracy when it was 2 or 3. In a 128K-token needle-in-a-haystack test with roughly 16,000 key-value pairs, moving a single pair changed accuracy by up to 40.2% for V4-Flash-Base and 34.8% for V4-Pro-Base, with gaps of 19.1% and 14.8% remaining after post-training; halving the compression stride in DeepSeek-V4.1-Flash narrowed the gap to 6.1% but did not remove it. Control models trained from scratch on the Qwen3-0.6B architecture showed the same periodic swings whenever fixed-length chunked compression was used, while a full-attention baseline did not, which the authors present as a structural flaw rather than a tuning issue.
