No explicit service-level pricing is outlined beyond potential costs from using integrated third-party models or services. - **Adopt for:** Unveils capabilities for LLM-powered Dart/Flutter applications with a focus on component chaining and RAG pipelines. - **License detail:** LangChain.dart operates under the permissive MIT License, allowing free use and modification as long as copyright and license information are preserved. ## Choose when ### Choose chainlit if… - chainlit is primarily Python; langchain_dart is Dart. - License: chainlit is Apache-2.0, langchain_dart is MIT. - Tags unique to chainlit: chatgpt, langchain, llm, openai. - Also covers AI Agents. - - When you want to develop conversational AI applications rapidly using familiar Python syntax. ### Choose langchain_dart if… - langchain_dart is primarily Dart; chainlit is Python. - License: langchain_dart is MIT, chainlit is Apache-2.0. - Pricing: Freely available for use and licensed under MIT. No explicit service-level pricing is outlined beyond potential costs from using integrated third-party models or services.. - Tags unique to langchain_dart: ai, dart, flutter, generative-ai. - Also covers Data & Retrieval. - You are developing Dart or Flutter applications that require integration with various Language Models (LLMs) without rewriting extensive connectivity code. ## When NOT to use chainlit - - Avoid if your development team is not comfortable with Python as Chainlit relies heavily on its ecosystem for rapid conversational AI development. - - Not suitable if you require customization in low-level components, as it abstracts a lot of these away to provide quick builds. ## When NOT to use langchain_dart - Your application does not require the chaining of multiple components or complex use cases such as RAG pipelines and can function with direct, simple API calls to language models. - You are looking for a framework that supports languages other than Dart; LangChain.dart is specifically designed for Dart/Flutter applications only. - You have specific requirements or constraints around licensing that do not align with the MIT License under which LangChain.dart is released. ## Common questions ### What is the difference between chainlit and langchain_dart? chainlit: Build Conversational AI in minutes ⚡️. langchain_dart: Build LLM-powered Dart/Flutter applications..
