@SawyerMerritt pothole avoidance can’t come soon enough

BREAKING: Tesla has officially released FSD V14.3 I'm downloading it in my Model Y right now. Here's everything that's new: • Improved parking location pin prediction, now shown on a map with a P icon. • Increased decisiveness of parking spot selection and maneuvering. • Rewrote the Al compiler and runtime from the ground up with MLIR, resulting in 20% faster reaction time and improving model iteration speed. • Enhanced response to emergency vehicles, school buses, right-of-way violators, and other rare vehicles. • Mitigated unnecessary lane biasing and minor tailgating behaviors. • Improved handling of small animals by focusing RL training on harder examples and adding rewards for better proactive safety. • Improved traffic light handling at complex intersections with compound lights, curved roads, and yellow light stopping - driven by training on hard RL examples sourced from the Tesla fleet. • Upgraded the Reinforcement Learning (RL) stage of training the FSD neural network, resulting in improvements in a wide variety of driving scenarios. • Upgraded the neural network vision encoder, improving understanding in rare and low-visibility scenarios, strengthening 3D geometry understanding, and expanding traffic sign understanding. • Improved handling for rare and unusual objects extending, hanging, or leaning into the vehicle path by sourcing infrequent events from the fleet. • Improved handling of temporary system degradations by maintaining control and automatically recovering without driver intervention, reducing unnecessary disengagements. Upcoming Improvements: • Expand reasoning to all behaviors beyond destination handling. • Add pothole avoidance. • Improve driver monitoring system sensitivity with better eye gaze tracking, eye wear handling, and higher accuracy in variable lighting conditions.

@omooretweets @stskeeps if someone wanted to read the actual whole prompt … docs.google.com/document/d/10m…

A startup is asking job candidates to have ChatGPT assess them for the role, and submit their chat log 👇 It sounds crazy, but I think we will see more of this AI knows us better than any other software (and most humans) ever will

@rebthebarber west needs more businesses and less bricks through the windows of said new businesses. walking down east passyunk is a vibe we just don’t get here in west.

Everyone on Philly twitter is talking about how great South Philly is, but I also am loving raising my kids in West Philly. We walk them to most things and we have so much beautiful greenery! Love living here. 🥰

@Camp4 bumps it sees well (riding above the road line/ same as debris). potholes, no chance. right through them CLUNK. philly roads are a war zone this time of year. hit a massive one and now disengage every time. one almost took me out 2 days ago going 50mph. 2 foot pothole 4 inch deep

@floundies I have not found that to be true. It’s better at seeing bumps in the road than I am!

We did a family road trip to Taos this week. 5 hours each way. Our Model Y did 100% of the driving. Zero interventions. One 12-min stop each way to charge during a bathroom break. Two 25-min charges in Taos while shopping. $57 total. Three things: 1) Most people don’t know that self-driving is solved. It’s mind-blowing and alleviates a surprising amount of mental load. When the supervision requirement is removed, it will be an even bigger game-changer. 2) Once you drive a Tesla, all other cars feel like relics from a bygone era. There are lots of subtle features that you don’t notice until you drive a regular car again. 3) Tesla is light years ahead of all other automakers and that gap will only grow because no other car company can design from first principles.

@elonmusk when will tesla fsd avoid potholes? feels like i have to grab the wheel 8 times a trip in philly.

Try Tesla FSD (self-driving)!

We’ve trained a multimodal AI model to turn routine pathology slides into spatial proteomics, with the potential to reduce time and cost while expanding access to cancer care.

@DeanTTraining i wouldn’t say unlimited, but would spend more for quality!

@floundies Is the budget unlimited?

Said it before, I’ll say it again: We’re about ~3 years away from EVERY SINGLE PERSON ON PLANET EARTH agreeing that this type of Machine is LIGHT YEARS better than Barbell Bench Press for building the Chest Just give it a little more time…the stragglers will catch up shortly!

You can just do things (genetically sequence your dog’s tumors and design a bespoke mRNA cancer vaccine to save her life)

No one tells you that parenting is just relearning the world through someone who thinks worms are friends & birds are miracles. It’s the most healing thing I’ve ever done. My daughter looked out the window this morning & said, everything is green & growing. I told her, you too. And something inside me whispered, so are you. Now I’m watching her hold flowers up to the sun while the light bends like it recognizes her. It’s funny, every spring I think I’m teaching my child about the world & every spring she proves she’s the one teaching me how to see it.

@riostoriches traded my ‘23 model 3 for a ‘26 model y and the hardware difference is night and day. self drive is incredible. 95% of my miles are my car driving me places autonomously so far.

The Math on a Tesla Model Y at 0% interest: $529/mo x 72 months = $38,088 The oldest Tesla Model Y (2020) currently sits at $20k - $25k which was 6 years ago In 6 years you would have paid $38,088 to own the same car that could be worth $20,000 Worth it?

@FinFreedom414 have a. have strived for b for years.

Imagine you had to choose your life at age 40: Option A: Single. No kids. $10M net worth. Travel anywhere. Total freedom. Quiet house. Quiet holidays. Option B: Married. 3 kids. $1M net worth. Drive a Toyota. Chaos every morning. Loud house. Full dinner table. Be honest, which life are you choosing?

Holy shit... Microsoft open sourced an inference framework that runs a 100B parameter LLM on a single CPU. It's called BitNet. And it does what was supposed to be impossible. No GPU. No cloud. No $10K hardware setup. Just your laptop running a 100-billion parameter model at human reading speed. Here's how it works: Every other LLM stores weights in 32-bit or 16-bit floats. BitNet uses 1.58 bits. Weights are ternary just -1, 0, or +1. That's it. No floats. No expensive matrix math. Pure integer operations your CPU was already built for. The result: - 100B model runs on a single CPU at 5-7 tokens/second - 2.37x to 6.17x faster than llama.cpp on x86 - 82% lower energy consumption on x86 CPUs - 1.37x to 5.07x speedup on ARM (your MacBook) - Memory drops by 16-32x vs full-precision models The wildest part: Accuracy barely moves. BitNet b1.58 2B4T their flagship model was trained on 4 trillion tokens and benchmarks competitively against full-precision models of the same size. The quantization isn't destroying quality. It's just removing the bloat. What this actually means: - Run AI completely offline. Your data never leaves your machine - Deploy LLMs on phones, IoT devices, edge hardware - No more cloud API bills for inference - AI in regions with no reliable internet The model supports ARM and x86. Works on your MacBook, your Linux box, your Windows machine. 27.4K GitHub stars. 2.2K forks. Built by Microsoft Research. 100% Open Source. MIT License.

@nextphlmayor just make walnut street pedestrian year round!

Open Streets has been so successful in Philadelphia that it is being expanded in 2026. We love to see it. Now the question is… how far can we take this? Sansom? Locust? Walnut? Chestnut?

@Romy_Holland swear they gave me really bad plantar fasciitis. used to wear them daily. don’t touch them anymore. PF mostly healed / gone.

i worked as the personal assistant for a billionaire at the height of the allbirds craze and one day he handed me 2 pairs of allbirds and said “i ordered these and they don’t fit. can you take them?” i was like “yep i’ll go return them” and he was like “no…what if you just…took them away so they weren’t in my house anymore and i didn’t have to think about them.”

Spring is almost here in #Philly Romanticizing the abundance of flowers that we will ultimately see. 💕

Many of you asked about the numbers👇 Heat pump costs $12,500 and takes 24 years to pay back. Adam’s miner setup cost $3,000 and earns him fresh bitcoin every day. Detailed blog post with schematics and calculations coming next week🤝​​​​​​​​​​​​

this is such a cute idea

@BritHugoboom amen!

I believe a lot of the loneliness epidemic is because we live in a generation of flakes. Before, you had to stay true to your word because if you were supposed to meet a friend at 1 pm for coffee and they were nowhere to be found, it was embarrassing. Now, people can cancel 5 minutes before via smartphone for “self care” or any random reason. Or they just don’t respond for 3 days and are like I’m so sorry I’m just now seeing this! Be for real, you’re on your phone nonstop. I think a lot of the loneliness epidemic is self inflicted. You should just be going out and doing things. I always tell my husband if he’s invited somewhere go because every single time without fail, you meet someone cool. It’s always worth it to go out.
