OpenAI and chip-design software developer Synopsys (新思科技) signed a binding multiyear agreement to jointly develop GPT-Synopsys, including revenue sharing.

OpenAI and Synopsys (新思科技; ticker SNPS in the supplied report) signed a binding multiyear agreement to jointly develop GPT-Synopsys, a specialized semiconductor-design model. The reported agreement includes revenue sharing and joint go-to-market cooperation, but no revenue-sharing percentages, minimum payments, or total contract value are supplied.

Synopsys will provide electronic design automation (EDA) tools and chip-design expertise, while OpenAI will provide frontier models and hosted infrastructure. OpenAI will license Synopsys EDA tools for development, and the planned model will run on OpenAI-hosted infrastructure with integration into Synopsys.ai and Synopsys Autopilot.

The reported data protections include encryption, configurable access controls, and a commitment not to use customer design data for model training. The signed agreement establishes a development arrangement, not a generally available product; one later message uses “ChatGPT-Synopsys,” while the detailed agreement reports consistently identify the planned model as GPT-Synopsys.

Separately, Synopsys reportedly raised full-year revenue guidance to $11 billion–$11.2 billion, from $9.69 billion–$9.74 billion, and adjusted earnings-per-share guidance to $19.04–$19.12, from $15.04–$15.10. It also projected approximately 15% fiscal 2027 revenue growth, described returning up to 50% of free cash flow through repurchases, and planned approximately $1 billion of buybacks over the coming months; the supplied reports do not establish that the OpenAI agreement caused those revisions.
