What Flux is
Flux turns engineering requirements into a connected design for a complete device. Electrical, mechanical, and firmware work stay in one live project, with checks and manufacturing outputs.
Grok can search the web and X, analyze files, and return a cited answer from multiple agents. Flux turns a hardware requirement into a designed and checked device with electronics and mechanical parts in one project.

Grok is xAI's assistant for chat, live search of the web and X, file and PDF analysis, vision, memory, Canvas, and voice.[1]
Multi-agent can run parallel agents and combine their work into a cited answer. Grok Imagine creates images and videos up to 15 seconds long.[1]
Grok supports chat, live search, and multi-agent research. Flux applies an AI hardware engineering workflow to a product requirement. The schematic, PCB, mechanical design, firmware, and manufacturing files stay in one live project.

Flux imports Labcenter Proteus SDF netlists with Specctra board exports. IPC-2581 revision B and C files become board projects with reusable footprint parts. | No built-in EDA project importer.[1] |
| Versions, branches, and merges | Full change history. The AI engineer forks a design into a second version, keeps both, and merges the changes that you pick. | No native hardware design version history.[1] |
| Who reviews the work | Electrical, layout, mechanical, and firmware engineers work together in one live browser project. | You prompt the assistant and review its responses.[1] |
| Product images, videos, and documents | Product images, product videos, datasheets, and regulatory documents, made from the design in the project. | Canvas supports writing; Imagine generates images and video.[1] |
| Mechanical CAD | Mechanical CAD is kernel agnostic, from enclosures to robot arms. | No built-in mechanical CAD design workspace.[1] |
| Mechanical simulation | Finite-element stress, thermal, and airflow simulation | No built-in mechanical simulation workspace.[1] |
| Mechanical manufacturing | STEP, STL, and 3MF files, plus quotes for 3D printing, CNC machining, sheet metal, and laser cutting | No built-in mechanical manufacturing workflow.[1] |
| CNC toolpaths and G-code | The AI engineer writes the toolpaths, the G-code, a toolpath preview, and a setup sheet for the parts that it designed. | No built-in CNC toolpath or G-code workflow.[1] |
| AI models | Frontier models from several providers, including Claude, OpenAI, and Gemini models | Grok models[1] |
| Tool licenses | A Flux plan contains the editor, mechanical CAD, parts data, simulation, and manufacturing files. | SuperGrok offers higher limits and multi-agent features.[1] |
| Team knowledge and rules | Document organization rules once. Flux applies them across projects and checks the designs. | Memory and live search support ongoing conversations.[1] |
| Parallel work | Flux moves work across projects in parallel and shares status updates. Major changes pause for approval. | Multi-agent combines parallel work into a cited answer.[1] |
Orchestration
Flux keeps the electrical design, mechanical parts, and firmware connected as your team works on a device.
