Prefer an active alternative unless you maintain a private fork or need a frozen dependency. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. - Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ## When NOT to use unsloth - Avoid using Unsloth if your primary requirement is cloud-based deployment and management; this tool focuses on local machine capabilities. - Do not use Unsloth Core or Studio if you do not have the necessary infrastructure to support running language models locally, especially if you lack GPU resources. - If security is a paramount concern and you cannot tolerate any potential risks of exposing local services (even with HTTPS tunnels), a fully managed cloud-based service might be more appropriate than虞 ## Common questions ### What is the difference between nni and unsloth? nni: An open source AutoML toolkit for automate machine learning lifecycle, including feature engineering, neural architecture search, model compression and hyper-parameter tuning.. unsloth: A web UI for training and running open models locally..
