OpenAI is developing ways for its models to help engineers design, simulate and build physical products, with work spanning mechanical and electrical engineering and system design. The company says its internal teams are already using ChatGPT and Codex to prepare drawings, set up simulations and revise designs across disciplines.
In one test, OpenAI used GPT‑6 to define requirements for a device that lets users talk to Codex. Its Astra model produced the device’s appearance, enclosure, printed circuit board, interface, firmware and software integrations. Two team members completed the side project in under a week, and a contract manufacturer produced a small batch of prototypes in under a month.
The device still needed multiple rounds of review before it was ready for manufacturing. OpenAI says Astra did not consistently account for production limits, tolerances or assembly requirements, highlighting areas where future models need to improve.
OpenAI’s hardware and infrastructure teams use ChatGPT and Codex to create and revise CAD models, prepare manufacturing drawings, configure simulations and review designs. The company says token usage across those teams has increased 23-fold since February.
OpenAI also reported results from BenchCAD 2.0, a test of models’ ability to reconstruct 3D parts and assemblies and identify circuit-board connections. A newer internal model scored an average of 0.875, compared with 0.594 for GPT‑6 Astra at its highest reasoning setting. OpenAI describes the results as an early indication of potential gains in engineering iteration, while noting that design is only one part of the broader engineering process.
The company is working with industry collaborators to assess model outputs for accuracy and practical use. With Chip Ganassi Racing, it is testing workflows that turn 3D scans of existing parts into editable CAD models and 2D manufacturing drawings, particularly when the original design files are unavailable. CGR engineers review the results for accuracy and manufacturability.
OpenAI has also announced a research collaboration with Mazda. Its teams are working with the automaker’s aerodynamics and crash-safety engineers to explore vehicle designs using simulations of airflow and structural behavior, while considering performance, styling and cost. OpenAI says it plans to share further progress and results in the coming months.
