Cerence and Nvidia Unveil Automotive Large Language Model CaLLM for New Generative AI Features in Cars

Are you ready to dive into the future of in-car user experiences? If so, you’re in the right place. In this blog post, we’ll be exploring the groundbreaking introduction of Cerence’s new large language model (LLM) for cars. Get ready to learn all about the Cerence Automotive Large Language Model (CaLLM) and why it’s set to revolutionize the way we interact with our vehicles.

Cerence CaLLM

CaLLM is not your average large language model. It’s been specifically tailored for in-car user experiences, utilizing Cerence’s multi-billion token automotive dataset to create a truly personalized and adaptable AI assistant. This model is not just about general knowledge – it’s designed to seamlessly integrate into your vehicle’s functions, features, and requirements. Plus, it can be customized for automakers, allowing for fine-tuning and the creation of bespoke applications.

But that’s not all – CaLLM also comes with a suite of native features, including Cerence Car Knowledge, allowing users to personalize their assistant and access built-in information tailored specifically for their vehicle. As Cerence CTO Iqbal Arshad puts it, this breakthrough in-car computing platform offers a unified conversational interface that will redefine the way we interact with our cars.

Future Integrations and Collaborations

Cerence has been at the forefront of car voice AI since its spin-off from Nuance, and it’s not slowing down anytime soon. From upgrading BMW’s AI platform to embedding Microsoft Teams in its voice AI system, Cerence is always looking for new ways to enhance the in-car experience. In fact, the company has recently inked a deal with iHeartMedia and Radioline to incorporate their audio content into its customizable voice assistant platform. And let’s not forget about the Cerence Exterior Vehicle Communication tool, which allows drivers to control their car with their voice from outside the vehicle.

This isn’t the first time Cerence has collaborated with Nvidia, either. The two companies have a long-standing partnership, with Cerence already supporting Nvidia’s Drive Concierge in-car infotainment system. Now, with the introduction of CaLLM, the stage is set for Cerence to lead the way with its automotive-specific LLM and in-car computing platform.

The Future of Automotive LLMs

So, what does all this mean for the future of in-car user experiences? According to Nvidia vice president of automotive Ali Kani, the possibilities are endless. With the use of generative AI and automotive LLMs, we can expect new, intuitive, and personalized user experiences both inside and outside the car. By tapping into Nvidia’s expertise in cloud and edge technologies, Cerence can more quickly train, scale, and deploy these models within their in-car user-experience platform, resulting in safer, smarter, and more enjoyable rides for all.


In conclusion, the introduction of Cerence’s CaLLM is set to redefine the way we interact with our vehicles. From its highly adaptable and customizable nature to its seamless integration into the in-car user experience, CaLLM is paving the way for a new era of automotive voice technology. Keep an eye on Cerence and Nvidia, as they continue to push the boundaries of what’s possible in the automotive industry.

If you’re as excited about the future of in-car user experiences as we are, then stay tuned for more updates on Cerence’s revolutionary CaLLM and the potential it holds for the automotive industry. The future is here, and it’s looking brighter than ever.
