TextGrad

Product: TextGrad is a Python package for building LLM-gradient pipelines that optimize text.
How it works: The framework implements backpropagation through natural-language feedback provided by LLMs.
API style: TextGrad offers an API for defining loss functions and optimizing them with text feedback, modeled on PyTorch’s API.
Optimization targets: The project describes optimizing text, code, solutions to problems, molecules, and prompts.
Use cases: The site highlights coding, scientific problem solving, reasoning, chemistry, and medicine applications.
Install: The documentation says to install TextGrad with pip using `pip install textgrad`.
Additional installs: The repository also documents conda-forge installation, a GitHub development install, and an optional vLLM extra.
Model providers: The repository says its experimental LiteLLM engine supports models available through LiteLLM, including Bedrock, Together, and Gemini.
Credentials: The project’s tutorials say an OpenAI or Anthropic key is needed to run the LLMs in those tutorials.
License: The repository provides the software under the MIT License, which includes an “AS IS” warranty disclaimer.
Support: The repository asks users to report issues with its experimental engines but does not specify a support service or response time.
Intended users: The site says TextGrad mirrors PyTorch’s syntax and abstraction, and that people who know PyTorch will find it familiar.
Research status: The repository states that TextGrad was published in Nature on 19 March 2025.
