TextGrad: dynamic optimization of your LLM
Summary
This post aims to be a comprehensive tutorial on Textgrad.
Textgrad enables the optimization of LLM’s using their text responses.
This will be part of SmartAnswer the ultimate LLM query tool which I will be blogging about shortly.
Why TextGrad?
- Brings Gradient Descent to LLMs – Instead of numerical gradients, TextGrad leverages textual feedback to iteratively improve outputs.
- Automates Prompt Optimization – Eliminates the guesswork in refining LLM prompts.
- Works with Any LLM – From OpenAI’s GPT to local models like Ollama.
What is TextGrad?
Bringing Gradients to LLM Optimization
Traditional AI optimization techniques rely on numerical gradients computed via backpropagation. However in LLM-driven AI systems, inputs and outputs are often text, making standard gradient computation impossible.
