What are the Risks & Limitations of Qwen1.5-72B

Limitations

Inference Speed: Significantly slower than the 14B and 32B versions.
VRAM Requirement: Needs at least two 80GB GPUs for 16-bit inference.
Context Jitter: "Needle in a haystack" recall is unstable past 64K.
Knowledge Decay: Cutoff prevents awareness of 2025–2026 events.
Formatting Errors: Struggles with strict JSON output in complex schemas.

Risks

Privacy Controls: Less robust than the 2026-era sovereign models.
Training Bias: Inherits societal prejudices from 2023-era web crawls.
Logic Shadowing: May overwrite user intent with "preferred" answers.
Tool-Use Failure: High rate of malformed API calls in agentic mode.
Safety Alignment: Can be "lobotomized" by over-alignment during tuning.

How to Access the Qwen1.5-72B

ModelScope Portal

Visit ModelScope.cn (Alibaba's model hub) to find the optimized versions of the Qwen1.5-72B model.
