Devin Desktop now runs local LLMs, replacing costly cloud setups

Devin has evolved from a coding agent into an orchestration platform that can manage multiple AI models and agents, allowing users to replace expensive cloud setups with local LLMs. The tool now supports local model integration through its Desktop interface, offering a cost-effective alternative to cloud-based coding assistants. Devin Desktop uses the Agent Client Protocol (ACP) to connect with compatible agents like OpenCode, which can route inference requests to locally hosted models such as Qwen 3.5-9B via Ollama. This setup provides a full coding agent experience—including file editing, terminal use, and multi-agent workflows—while keeping model inference on the user's own hardware, eliminating per-prompt API costs. The experience quality depends heavily on the local model's capability and hardware performance, with smaller models requiring tasks to be broken into smaller steps. However, users with powerful Macs or PCs can run stronger models like Qwen3-coder-30B-A3B for noticeably better results, making the local setup a practical option for those with adequate hardware.
