With the popularity of AI programming assistants, developers are increasingly relying on cloud-based large models like Claude and GPT-4 to assist with coding. However, these services usually charge by token, and even for relatively simple tasks—such as generating boilerplate code, writing unit tests, or performing simple code refactoring—developers consume valuable API call credits. Over time, these 'daily expenses' add up to a significant cost burden.
More importantly, many developers have privacy concerns about sending code to the cloud for processing, especially when it involves sensitive business logic or proprietary codebases. How to enjoy the convenience of AI-assisted programming while reducing costs and protecting data privacy has become an urgent issue for the developer community to solve.
