STMicroelectronics today announced the release of STM32 AI Model Zoo version 4.0, adding a suite of new vision, audio, and sensing models that enable developers to prototype embedded AI solutions more quickly. The expansion is part of the company’s strategy to accelerate the adoption of “physical AI” across wearables, smart cameras, and industrial automation, giving designers a broader set of pre‑trained models that can be tuned to specific hardware configurations.
In the same announcement, the company introduced the STM32V8, its first microcontroller built on an 18 nm process. The device houses an Arm Cortex‑M85 core that can run at up to 800 MHz, 4 MB of embedded phase‑change memory (PCM), and a suite of advanced security features. Manufacturing takes place in ST’s 300‑mm fab in Crolles and through a partnership with Samsung Foundry, positioning the MCU for high‑performance industrial and edge‑AI applications that previously required more powerful processors.
A key validation of the STM32V8’s capabilities came from SpaceX, which selected the chip for its Starlink mini‑laser system. The design win demonstrates the MCU’s reliability in harsh low‑Earth‑orbit environments and signals that ST is capable of meeting the stringent requirements of space‑grade electronics.
The product launches reinforce ST’s focus on high‑growth segments such as industrial automation and edge AI, while supporting its broader silicon photonics and silicon‑on‑ceramic (SiC) initiatives. The 18 nm process and PCM give the STM32V8 a competitive edge in power efficiency and memory density, allowing it to replace more powerful application processors in many use cases and opening new revenue streams in demanding embedded markets.
The announcement was met with a muted market reaction, reflecting investor caution amid ST’s Q3 2025 financials. Net revenues for the quarter were $3.19 billion, flat year‑over‑year, and net income fell to $237 million from $351 million. The modest earnings picture, combined with the need to see how the new products will translate into revenue growth, tempered enthusiasm for the launch.
Management emphasized the strategic importance of the AI Model Zoo expansion. Stephane Henry, VP of ST’s Edge AI Solution Group, said the new models “help developers jump‑start projects and strengthen deployment infrastructure,” underscoring the company’s commitment to making physical AI a reality. The company’s leadership views the STM32V8 as a key enabler for future high‑performance embedded AI solutions.
Overall, the launch signals ST’s continued investment in advanced process nodes and AI capabilities, positioning it to compete in high‑performance embedded AI markets and secure design wins like SpaceX, while navigating current earnings pressure and seeking to translate product innovation into future revenue growth.
