Honest assessment
Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Bender primarily supports Swift, which restricts its usability for developers who prefer or are more comfortable with other languages like Python or JavaScript.
Being optimized for macOS and iOS devices means it may not perform as well on non-Apple hardware, limiting its cross-platform utility.
The open-source nature of Bender has resulted in a smaller community compared to more established frameworks like TensorFlow or PyTorch, leading to fewer contributed features and slower issue resolution.
Setting up the environment requires detailed knowledge of Metal API and Swift, which can be challenging for beginners or those new to Apple's ecosystem.
