DSolve[Derivative[1][y][x] == (I/2)*x^2*(I - 2*Sqrt[-x^3 + 6*y[x]]),y[x],x]
\[\left \{\left \{y(x)\to \frac {1}{6} \left (-W\left (-i e^{-x^3-1-6 c_1}\right ){}^2-2 W\left (-i e^{-x^3-1-6 c_1}\right )+x^3-1\right )\right \}\right \}\]

dsolve(diff(y(x),x) = 1/2*I*x^2*(I-2*(-x^3+6*y(x))^(1/2)),y(x))
\[i \ln \left (x^{3}-6 y \left (x \right )-1\right )+2 \sqrt {-x^{3}+6 y \left (x \right )}-2 \arctan \left (\sqrt {-x^{3}+6 y \left (x \right )}\right )+2 i x^{3}-c_{1} = 0\]
