Cline is an open-source AI coding assistant that enhances development workflows by integrating powerful language models directly into popular integrated development environments (IDEs). By partnering with Baseten's model-serving infrastructure, Cline offers users access to advanced models such as DeepSeek R1, Kimi K2, and Qwen3 Coder, optimized for various coding tasks. The integration facilitates building complex applications, debugging, and exploring new technologies, providing tools for modern software development. To use Cline, developers must install it into their IDE and configure Baseten with an API key for model access. Cline offers "Plan" and "Act" modes, allowing users to either architect solutions or implement them directly, as demonstrated by generating a browser-based Flappy Bird game. The choice of model depends on the coding scenario, with Qwen3 Coder suited for rapid prototyping, Kimi K2 for complex integrations, and DeepSeek R1 for in-depth analysis and problem-solving. Users are encouraged to experiment with the full range of models available through a single Baseten API key to enhance their development processes.
