   Cogitator – A Python Toolkit for Chain-of-Thought Prompting▲54

   Hi everyone, I made an open-source Python toolkit/library, named Cogitator, to make it easier to try and use different chain-of-thought (CoT) reasoning methods. The project is at the beta stage, but it supports using models provided by OpenAI and Ollama. It includes implementations for Cot strategies and frameworks like Self-Consistency, Tree of Thoughts, and Graph of Thoughts. GitHub link of the project: https://github.com/habedi/cogitator
