It supports commercial usage with a permissive MIT license and is implemented in C++. ## Choose when ### Choose Lumos if… - Lumos is primarily TypeScript; gpt4all is C++. - Tags unique to Lumos: chrome-extension, langchain, langchain-js, llm. - Also covers Developer Tools. ### Choose gpt4all if… - gpt4all is primarily C++; Lumos is TypeScript. - Tags unique to gpt4all: ai-chat, llm-inference. - - When you require on-device inference capabilities without reliance on cloud services. ## When NOT to use Lumos - Last GitHub push was 535 days ago (dormant maintenance, Jan 26, 2025). Validate activity before betting a new project on Lumos. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. - Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. ## When NOT to use gpt4all - - In environments strictly requiring models supported by mainstream frameworks like TensorFlow or PyTorch, as GPT4All focuses on its standalone implementation. - - When the project demands seamless integration with popular cloud infrastructures that don't align well with local deployments. ## Common questions ### What is the difference between Lumos and gpt4all?
