 ### Model Description
 
-<!-- Provide a longer summary of what this model is. -->
+Specialize with STEM and science for science purpose AI. This idea captures the need to design artificial intelligence systems that aren’t just generalists but are deeply tuned for scientific exploration and problem-solving. By focusing on science, technology, engineering, and mathematics, such AI can move beyond surface-level pattern recognition and instead tackle real challenges in physics, biology, chemistry, and mathematics with rigor. Imagine AI models that assist in discovering new materials, predicting protein folding with precision, optimizing renewable energy systems, or solving abstract mathematical conjectures. These are not applications where shallow training suffices—this requires an AI mindset that mirrors the scientific method: hypothesize, test, refine, and explain. A purpose-built science AI would act less like a chatbot and more like a laboratory collaborator, accelerating the pace of discovery while remaining grounded in evidence and reproducibility.

 ## Bias, Risks, and Limitations
-
-<!-- This section is meant to convey both technical and sociotechnical limitations. -->
-
-[More Information Needed]
+- The model is biased toward **STEM reasoning tasks** and may underperform on humanities or everyday reasoning.  
+- Risk of **hallucinated precision**: outputs may appear mathematically rigorous but contain subtle errors.  
+- Users should treat results as **hypotheses, not ground truth**.  
 
 ### Recommendations
+- Always apply **human oversight** in professional or research-grade applications.  
+- For safe deployment, pair the model with verification tools (e.g., symbolic solvers, fact-checkers).  
 
-<!-- This section is meant to convey recommendations with respect to the bias, risk, and technical limitations. -->
