OpenJet
What OpenJet is
OpenJet is an open-source local LLM coding agent and Python SDK that profiles hardware and configures a model to run on your own machine. Its coding assistant provides chat assistance, a coding agent, codebase indexing, and terminal access on macOS, Linux, API, and self-hosted setups. The SDK can embed a local model in an application and provision model files at build time. Listed GGUF builds include Qwen3.5 4B and 9B, Qwen3.8 27B, Qwen3.6 35B-A3B, and Gemma 4 26B for llama.cpp. OpenJet can connect to Ollama, LM Studio, or an existing llama-server through OpenAI-compatible endpoints. MCP tools and device sources such as cameras, microphones, and GPIO are supported. Offline operation is available after runtime and model assets are installed. Local models keep code and prompts on the machine; optional Slipstream routing sends selected work and repository content to external providers.
Who it suits
It suits developers and teams wanting local or offline coding assistance, especially privacy-sensitive small teams, AI consultancies, labs, and GPU workstation owners. The pilot page also names Jetson users as an intended audience.
What it does well
- Local model keeps code and prompts on-machine
- Codebase indexing and terminal access
- Supports Ollama and LM Studio connections
- Offline operation after assets are installed
- MCP tools and device sources
What to know first
- No code completion
- No supported IDEs listed
- Recommended hardware needs substantial memory
- Cloud routing sends content to providers
