1st Place: Nova taught Grok to reverse-engineer binaries into clean C. Started with 262KB GameBoy ROMs, ended up rebuilding a 1995 car’s ECU runtime. Theo C Supratik Panuganti

Congratulations to the winners of the SpaceXAI Grokathon 2026. Here are the top 3 projects that were built in the 12 hours!

2nd Place: Signal embeds followers’ bios, posts, and engagement into a living graph and A/B tests different launches using simulated populations of your following, so every post hits maximum engagement. @adibilawar @jasonlai150_ @SChen1249 @JeffreyZh0u

3rd Place: ThinkVoice lets you speak without moving your mouth by combining Grok Voice with brain-sensing technology. It understands the conversation, suggests what you might want to say next, and lets you select a response using subtle motor movements. @Daniel_farinax @yangchasiu @elithpalomino

We are rapidly scaling our engineering team! Join us at

@elonmusk @theoc____ @supratikp07 @henryzhangumich From Game Boy ROMs to a 1995 car ECU. That’s a wild jump in difficulty.

@theoc____ @henryzhangumich ‼️‼️‼️
@theoc____ @supratikp07 @henryzhangumich So can Nova take the Tesla car software binary and decompile it and then we can ask it to add in stuff we want? 😉

@theoc____ @supratikp07 @henryzhangumich That’s seriously impressive. Turning binary reverse-engineering into clean, understandable C is a huge leap. 🔥🤖

@theoc____ @supratikp07 @henryzhangumich Can we use AI tools like this to detect spyware code embedded in defense parts imported from China? Decompile the onboard memory and analyze it for any phone-home commands?

@theoc____ @supratikp07 @henryzhangumich woah

@theoc____ @supratikp07 @henryzhangumich Congrats, really cool ideas and use cases.

@theoc____ @supratikp07 @henryzhangumich Can it use stored libraries and classes too ? Maybe even some optimized inline ASM code? I would play around with that for months.

@theoc____ @supratikp07 @henryzhangumich Grokathon results are wild. Reverse-engineering binaries into clean C, engagement simulation graphs, and brain-sensing voice control — all built in 12 hours. This is what happens when the model is actually useful.

@elonmusk @theoc____ @supratikp07 @henryzhangumich That’s awesome

@theoc____ @supratikp07 @henryzhangumich Crazy work!

@theoc____ @supratikp07 @henryzhangumich Reverse-engineering old binaries into clean C and rebuilding a 1995 car ECU runtime from scratch, is a pretty wild demonstration of where AI coding is headed.

Rebuilding a legacy ECU runtime from raw binary using Grok is an incredible demonstration of AI-assisted systems engineering. Bridging the gap between legacy automotive architecture and modern autonomous hardware software stack design is a massive frontier. Congrats Nova team! 👏

@elonmusk @theoc____ @supratikp07 @henryzhangumich Impressive work by the Nova team .. teaching Grok to turn raw binaries into clean C, from GameBoy ROMs all the way to a 1995 car ECU. Reverse-engineering just leveled up. 🚀

@theoc____ @supratikp07 @henryzhangumich So sick

@theoc____ @supratikp07 @henryzhangumich They are the ones who built Nova, and we are directing the payments to them. Good luck with your SpaceX career! $nova FXFmeTMRGN7wUyMQotZHEW9K6Gn4uR1cMZFHmb7Vpump

@theoc____ @supratikp07 @henryzhangumich Cool! Now decompile machine learning neural net to C. Start with a small one.

@theoc____ @supratikp07 @henryzhangumich Yeah this is awesome and first prize material!

@elonmusk @theoc____ @supratikp07 @henryzhangumich Kandis needs @XMoney option!!!!

@theoc____ @supratikp07 @henryzhangumich This is insanely valuable!!!

@theoc____ @supratikp07 @henryzhangumich Wao! The agent uses a careful test harness to take binary programs apart, rebuilds them into clean code, turns simple examples into fun browser games that people can remix, and turns complex real-world systems into interactive 3D simulations you can control and explore.

@theoc____ @supratikp07 @henryzhangumich This is fantastic! Think of all the stuff that's hidden in random legacy executables that can now be fixed, extended, and otherwise leveraged!

@elonmusk @theoc____ @supratikp07 @henryzhangumich

@theoc____ @supratikp07 @henryzhangumich lfg @henryzhangumich

@theoc____ @supratikp07 @henryzhangumich Congratulations everyone!👏🏻🙌🏻🎊

CreativityMaxy 😂 Fun, open engagement, user creativity door is wide open Great work👏🏽 Being first place, I have to assume Copy Right authorization was granted ( Kirby ) Will this be managed / monitored in the future? Or will every user have the wheel and go where ever they please with 0 liability using Nova?

@theoc____ @supratikp07 @henryzhangumich 🔥

@elonmusk @theoc____ @supratikp07 @henryzhangumich Impressive🔥

@elonmusk @theoc____ @supratikp07 @henryzhangumich Super Micro's guidance beat came alongside broader strength in AI-adjacent hardware names this week. One earnings call rarely moves a sector, but it does tell you where the next few quarters of capital expenditure are already committed.

@theoc____ @supratikp07 @henryzhangumich @grok ELI5 and add necessary context and definitions and core assumptions

@elonmusk @theoc____ @supratikp07 @henryzhangumich Wow
