TextGrad: Automatic ''Differentiation'' via Text -- using large language models to backpropagate textual gradients. Published in Nature.

+Novel LLM-based backpropagation approach with strong academic credibility (published in Nature)
+Familiar PyTorch-like API makes gradient-based text optimization accessible to ML practitioners
+Extensive model support through litellm integration, compatible with virtually any major LLM provider

-Experimental new engines may have stability issues as the project transitions from legacy implementations
-Text-based gradients are inherently less precise than numerical gradients, potentially causing slower convergence
-Heavy dependency on external LLM APIs can result in significant costs and latency for optimization tasks

•Prompt optimization for LLM applications requiring systematic improvement of prompts based on output quality
•Fine-tuning text generation systems by optimizing intermediate text representations using gradient-like feedback
•Developing text-based loss functions for natural language tasks that need iterative refinement through LLM evaluation
