@AntonyVo @BrainsAndTennis @SwingVisionApp @comma_ai Sure but it’s not realistic for it to be 100% in all scenarios. There’s a long tail of edge cases.

Similar to Tesla Autopilot, you need to be able to take over and get to the destination manually. The second part is the bigger problem currently given the constraints of the UX.

[Swupnil Sahai 🎾🧠 @SwupnilSahai]

@AntonyVo @BrainsAndTennis @SwingVisionApp @comma_ai Yea most of these are not AI issues and just inflexibility in the user interface/data manipulation. Ability to add/delete/merge points would probably help a ton.

And yes partial scores coming soon!

[Swupnil Sahai 🎾🧠 @SwupnilSahai]

@BrainsAndTennis @AntonyVo @SwingVisionApp Can this run for 2 hours on a phone without killing the battery and overheating the device? Does it work across a variety of court angles, setup heights, surfaces, lighting conditions, etc? Can it handle edge cases across amateur play that result in support tickets? 😭

[Swupnil Sahai 🎾🧠 @SwupnilSahai]

@AntonyVo @BrainsAndTennis @SwingVisionApp Running a small model within the constraints of a phone is infinitely more difficult than burning tokens on an LLM. We are improving every month and the state of the art in mobile but it takes time to get this working accurately for all customers.

It’s not good that the United States Government is more hostile to Anthropic, an American company opposed to spying on Americans, than it has been to TikTok, an arm of the Chinese surveillance state.

I didn’t realize we don’t pursue pedophiles if the stock market is doing well. Thank you, Pam Bondi, for that clarification.

[Ron Filipkowski @RonFilipkowski]

I might believe these Epstein allegations about Trump if he was accused in the past by 27 different women of sexual assault, found liable for it, bragged on tape/video about grabbing women, going backstage while girls were changing at pageants, and how hot his daughter was.

Tech CEOs and thoughts leaders who normally have a lot of say about the Billionaire Tax / Mamdani fearmongering

will suddenly have nothing to say on ICE gestapo thugs shooting people on the streets in plain sight.

RFK Jr saying "none of the 72 vaccines given to children have been tested against placebo "

The reality :

- Children are not given 72 vaccines
- The ones they are given have been tested against placebo

This serial liar is your HHS Secretary.

[Swupnil Sahai 🎾🧠 @SwupnilSahai]

@mkanapaka @SwingVisionApp We tested this. It’s quite inaccurate and mostly generic advice rather than specific to your actual form.

And it’s not on-device inference. So you will pay more for worse feedback.

We are building an on-device version of this and have better training data than the open web.

[Swupnil Sahai 🎾🧠 @SwupnilSahai]

@bowtiedgerman @tonal solves this. It’s counterintuitive but the instructors make every workout feel personal & fun.

18 months in & I feel no loss of human connection and have no desire to ever pay for a public gym again.

This is from someone who hates WFH & prefers going into the office!

[Swupnil Sahai 🎾🧠 @SwupnilSahai]

@jsjoeio @FarzaTV Try @SwingVisionApp - ball tracking is real-time, on device. Zero compute costs :)

[Swupnil Sahai 🎾🧠 @SwupnilSahai]

@MtcPatton70195 @MarioNawfal Yes! The cost is zero for us to run the models, so we don’t have to charge customers as much 🙂

⚫️ UNCANNY VALLEY: AI IN SPORTS — FAIR OR UNFAIR ADVANTAGE?

Are we witnessing the end of human merit in sports?

@SwupnilSahai—ex-Tesla engineer and co-founder of @SwingVisionApp—thinks AI isn't just changing the game. It's redefining the rules, the training, even the players themselves.

From iPhones that out-call line judges to AI coaching that levels the field, this episode explores what happens when everyone has a superpower—and why the next era of sports might feel more like cyborg vs. cyborg.

But Swupnil says the real win? It's access. AI could democratize elite performance for everyone.

Welcome to The Uncanny Valley Weekly Series with @operationdanish, Fridays at 4:20PM ET, ONLY on 𝕏.

Episode 8: THE AUGMENTED ATHLETE—ARE WE ALL AI JUICING NOW?

00:22 – “It’s already better than us at some tasks.”

01:21 – Why user-friendly AI will explode in the next 24 months.

02:41 – Most people still underestimate what’s coming.

04:30 – Universal basic income? Guardrails? Swupnil says we better start now.

06:08 – “AI might be more dangerous than nukes.”

07:30 – The kill switch question—and why Tesla has it right.

08:27 – AI is now coaching, calling, and editing your tennis matches.

09:25 – AI > coach? Why SwingVision is training better and cheaper.

10:29 – The @elonmusk moment that changed everything.

12:48 – On-device AI: faster, private, and zero marginal cost.

15:21 – No data? No problem. Building training sets from scratch.

16:32 – AI won’t ruin sports—it could equalize them.

17:43 – Microchips and implants: when tech becomes the body.

19:29 – Will SwingVision become more than sports?

20:00 – Craziest prediction: AI commentators for every high school game.

21:50 – Subscription vs. surveillance: the real cost of AI access.

23:42 – Hardware is king—and it’s catching up fast.

24:54 – “10 people will run the next billion-dollar startup.”

25:33 – His biggest fear? “Regulation is too slow—and bad actors move fast.”

26:06 – His message to AGI in 2040: “Hey... we come in peace.”

28:33 – Trusted by pros like Andy Roddick + 100+ D1 teams.

29:36 – Are we all just juicing with AI now?

30:48 – “It’s still up to you. It’s on your racket. Literally.”

69 𝕏 MINUTES | SWINGVISION CEO: AI AND AUGMENTED REALITY COULD CHANGE TENNIS FOREVER

CEO of SwingVision, Swupnil Sahai:

"When it comes to tennis, AI can augment your training and help you get better faster, but it still comes down to you to hit the shot and execute.

Ultimately, computers enable everybody to have an even playing field, which is not necessarily the case today.

Today, with Swingvision, what’s really cool is that you can just set up your own iPhone behind the court, and it can call the lines for you.

The AI is able to process the video footage on the court at 60 frames per second, which is much better than what the human eye can do.”

@seti_park @aelluswamy The 2016 Vision crew @jmusk 🤠

[Swupnil Sahai 🎾🧠 @SwupnilSahai]

@seti_park Fun fact: James & I met as interns on Autopilot back in 2016 when David Nister led the first 6-person Vision team.

@aelluswamy was a junior engineer and my mentor that summer - he eventually became my boss and took over the entire Autopilot team before my eyes 🥲
