Comma 4, Body 2, and Beyond: Inside the Next Era of Open-Source Autonomy

Comma Con 2025: Outwit, Outplay, Outlast

San Diego, CA — November 2025

This year’s Comma Con felt electric from start to finish. The energy in the room reflected just how far the community has come — and how much further it’s about to go. Between Adeeb’s sharp and self-aware Oh Shit, End the Sale talk and George Hotz’s Survivor-themed Outwit, Outplay, Outlast, attendees got an unfiltered look at Comma AI’s mindset as the company continues to push open-source automation and embedded intelligence forward.

It was especially cool to see the evolution of both Comma as a company and the devices themselves during Adeeb’s presentation. He walked the audience through the journey from early prototypes to polished hardware, underscoring how design, efficiency, and simplicity have become core to Comma’s DNA.

Then George took the stage, delivering one of the most inspiring talks of the event. He reflected on how Comma has survived and will continue to survive even as so many well-funded competitors have come and gone — their billions in investments effectively evaporating while Comma stayed lean, adaptive, and focused. It was a reminder that innovation isn’t just about resources — it’s about persistence, clarity, and the courage to build differently.

🚀 The Big Reveal: Comma 4

The biggest shock came with the official unveiling of the Comma 4 device. It’s smaller, sleeker, and somehow even more refined than anyone expected. The crowd reaction said it all — a mix of disbelief and validation from the “told-ya-so” crowd that’s been predicting new hardware for months.

Under the hood, the specs aren’t radically different from the Comma 3X, but there are a few key refinements. The Comma 4 uses a Snapdragon 845 MAX instead of the standard 845, offering modest performance improvements, but the real breakthrough lies in the new physical design. The updated chassis delivers substantial thermal efficiency gains, allowing the device to run cooler and more consistently under heavy load. Combined with a reduction in internal components, the redesign also makes the Comma 4 far easier and more cost-effective for Comma AI to manufacture — an important step toward scalability.

Adeeb mentioned during his talk that this is the first Comma device he truly feels reaches the level of a consumer electronic — something that looks, feels, and performs like a polished product ready for everyday use. It’s not just a developer tool anymore; it’s a sign that Comma is crossing over from enthusiast hardware into something that can stand confidently alongside mainstream tech.

This iteration isn’t about cramming in new specs; it’s about refinement and maturity. The Comma 4 represents a carefully engineered evolution — streamlined, cooler-running, and built for the next phase of open-source driver-assist hardware.

⚙️ Hardware Innovations: Body 2 and Compute 100 W

Another major highlight was the hardware showcase — especially the new Body 2, priced at just $200. George Hotz explained that Comma is aiming the Body 2 squarely at the toy market, keeping the price extremely low to get it into as many hands as possible and letting the community figure out creative and useful ways to build on it.

This approach captures Comma’s open-source spirit perfectly. The Body 2 appears to be a streamlined, second-generation version of the original Comma Body robotics kit — smaller, cheaper, and far more accessible to hobbyists, students, and developers who want to explore real-world AI and robotics. While it’s not yet clear how feature-rich it will be compared to the first-generation Body, its low entry cost and modular design could make it a gateway device for a whole new generation of creators.

Alongside Body 2 was the Comma Compute, a 100 W external processing unit designed to leverage an eGPU for running much larger models on Comma hardware. Attendees got a first look at the compute kits — available as ready-made or build-your-own-case versions — showing Comma’s continued focus on keeping high-performance experimentation open and affordable.

🌤️ Sunnypilot’s Growing Role

It was also great to see Sunnypilot represented with their own booth, where they discussed how the new hardware will shape third-party development. They previewed a web-based settings manager that allows remote configuration of Comma 3X devices — a huge quality-of-life improvement for anyone managing multiple installs.

They also confirmed that Navigate on Sunnypilot will soon make its return, reintroducing smarter routing and adaptive navigation features that many have been eager to see back in action. With the community already experimenting on new hardware, Sunnypilot’s forward-thinking development pace ensures that innovation won’t slow down as the ecosystem evolves.

🧠 Culture, Code, and Community

Comma Con 2025 reinforced why this movement is so unique. It’s not just about self-driving or assistive automation — it’s about creating the foundation for real-world AI that anyone can learn from, contribute to, and build upon. The talks, the booths, the hallway conversations — all of it captured a sense of curiosity and shared purpose that’s hard to find anywhere else in tech today.

From Adeeb’s reminder that vision and honesty go hand-in-hand, to George Hotz’s message about endurance and adaptability paired with a clear mission, this year’s event was more than a showcase — it was a checkpoint on a much larger journey. And judging by what we saw in San Diego, that journey is accelerating faster than ever.
