Model Comparison on Mechanical Engineering Drawings
rlv1204 · reddit · 2026-07-12
In a mechanical engineering context, the author tested ChatGPT 5.6 and Fable 5 by asking them to interpret two hydraulic diagrams, find differences between two cranes, and verify if specific lines connect to the auxiliary winch area.
Conclusions:
- Fable 5 caught two errors in ChatGPT 5.6's response, notably the latter's failure to correctly handle the fact that "the crane has three winches."
- In practice, such tools can assist with failure analysis and equipment comparison, but they still cannot be fully trusted in high-risk maritime/industrial hydraulic scenarios.
- A usage anomaly was also noted: Fable 5 consumed 100% of the session, while ChatGPT in "High Noon" mode used only 1%.
