 "details": "Qwen3.6-35B-A3B-DFlash: rope_scaling rewritten in a different format ({\"beta_fast\":32,\"beta_slow\":1,\"factor\":64,\"original_max_p... to {\"beta_fast\":32,\"beta_slow\":1,\"factor\":64,\"original_max_p...); a loader that only reads the old format rejects or ignores the new one (2026-04-17).\n\nRepository: https://huggingface.co/z-lab/Qwen3.6-35B-A3B-DFlash. Revisions from 92297e6cfd224a858c3ba24281f7c43ae6c1bb4a onward carry this change; a pin at 1f71bf5b8b3d13c6068284ca02b2c046cc0b5aed or earlier does not.\n\nChanged keys:\n- rope_scaling: {\"beta_fast\":32,\"beta_slow\":1,\"factor\":64,\"original_max_position_embeddings\":4096} -> {\"beta_fast\":32,\"beta_slow\":1,\"factor\":64,\"original_max_position_embeddings\":4096,\"rope_type\":\"yarn\",\"type\":\"yarn\"} (structural)\n\nThis record says what the change does mechanically. It is not a report that anything broke for anyone.",
