 - Library Support: Whether the framework has a library to support the optimizer.
 - Speed: TextGrad is about 2-3x slower than OptoPrime (Trace). OPRO has no concept of computational graph, therefore is very fast.
-- Large Graph: OptoPrime (Trace) represents the entire computation graph in context, therefore, will have issue with graphs that have more than hundreds of operations. TextGrad does not have such issue.
+- Large Graph: OptoPrime (Trace) represents the entire computation graph in context, therefore, might have issue with graphs that have more than hundreds of operations. TextGrad does not have the context-length issue, however, might be very slow on large graphs.
 
 We provide a comparison to validate our implementation of TextGrad in Trace:
