Day 26, 27 and 28: OpenAI is officially giving us two banked resets, which means they want us sitting on a mountain of spare tokens for... GPT-6.1 ASTRA, OBVIOUSLY. Or something just as big. Get ready, because next week is going to be on fire.
Day 26/ You can now easily switch between multiple accounts on mobile, and coming soon to desktop too. Next two days will be resets… banked… do with this what you may 👀. help.openai.com/en/articles/…

Everyone knows Tibo from the Codex resets. Meet Thariq - the guy who did something similar for Claude Code. Thariq Shihipar (@trq212) > From Toronto, based in SF > Studied Engineering Science at the University of Toronto + Master’s at MIT Media Lab > Co-founded Chime (acquired by HubSpot) and scholarly platform PubPub > Founded YC-backed gaming company One More Multiverse (raised ~$17M) > Joined Anthropic in 2025 and spent over a year on Claude Code > Worked on skills, context engineering, and dynamic agent workflows > Helped cut the system prompt by ~80% as models got stronger > Became one of Claude Code’s most visible faces on X by actually talking to users > Left Anthropic in late October 2026 for a break before his next thing He went from building startups and games to helping shape one of the biggest coding agents, while staying unusually close to the community. The person many developers associated with Claude Code just stepped away right before Anthropic’s IPO.
experimenting with a lil personal project: an AI-native macOS dock with custom modes (writing, building, etc.) to help me stay focused my agent is able to customize mode behavior and add new modes, it uses jev to classify my activity + notifications in real time & act on them

GPT-6.1 Luna is showing its first signs of life, and I believe OpenAI is getting ready to launch it. Honestly, seeing it before GPT-6.1 Astra would make sense, especially if Astra is being saved for the final day of Tibo's 28 Days. The model lineup is almost complete, with only GPT-6.1 Luna and GPT-6.1 Astra left to round out the entire family. What I'm most interested in is the pricing. If Luna ends up being slightly less capable than GPT-6.1 Terra but costs a fraction of the price, it could be a serious competitor to Haiku.

GPT-6.1 Astra coming soon. My biggest question is whether it'll beat Opus 5.5 by a huge margin or just barely edge it out. I'm rooting for Opus to get publicly humiliated, with OpenAI finally getting back in the game. GPT-6 Astra already feels like an old model to me.

What if the future of robotics combines machines with living cells? Researchers at MIT have built a tiny swimming robot powered by living muscle cells that respond to light. It can move and steer a fascinating mix of biology and engineering. Could living cells play a bigger role in the robots of the future?

Are you ready to fly? Flying vehicles are no longer just science fiction. They are shaping the future of mobility. Maybe one day the sky will be our new highway!
🚨 Ravi Tamta, a BA graduate from Almora, Uttarakhand, has built an electric flying vehicle without engineering degree.
Readers added context they thought people might want to know
Ravi Tamta assembled the HAPIDA SKYNeX prototype from components including some sourced from China rather than manufacturing a fully original design from scratch; similar single-seat electric eVTOL vehicles are commercially available from Chinese suppliers. thedailyjagran.com/india/uttarakh… dainiktribuneonline.com/news/explainer… x.com/xwaceem/status…

Just saw @SpaceXSI launch The X Subscription and this is the first AI plan that actually feels complete. Space X SI put Grok, Grok Bot, Cursor and X Premium under one plan. Finally one bill and one shared usage pool instead of juggling four different subscriptions. $30 gets you what used to cost ~$90 combined, and you get more model usage per dollar. Idea → code → finished work → post, all in one place. @elonmusk @Cursor_ai @Grok @X this is the standard other companies need to match.
We've unified plans across Grok, Cursor, and X Premium. Introducing The X Subscription.

You are using X, you post something, and it sometimes travels to a wide range of audiences, and others are travelling into the 20s, kind of impression. First, that's a wild difference, but have you ever thought about why that happens? It got me curious about what X actually does before deciding who sees your post. So I went through its published algorithm code, and some of the things I found were really surprising. For example: X's algorithm gives a weight of +0.5 and a report −234. So one report cancels 468 likes? Nope. X literally added a warning in the source code saying that's wrong. Those weights multiply predicted probabilities, not actual engagement counts. And reports are over 1,000x less likely than likes. Here's how the pipeline actually works: 1. Discovery: Thunder finds posts from accounts you follow. Phoenix and SimClusters discover posts outside your network. If your post never enters someone's candidate pool, ranking doesn't even matter. 2. Prediction: Phoenix estimates whether that viewer might like, reply, quote, share, follow, click, keep reading, or react negatively. Different viewer, different score. There isn't one universal popularity score attached to your post. 3. Distribution: Out-of-network posts face a discount. Repeated posts from the same author lose some priority. There's even a mechanism to give underexposed authors a chance. Posting more doesn't automatically mean getting more reach. 4. Visibility: This one gets overlooked. Separate filters can remove posts from recommendations, sometimes only for non-followers. The For You pipeline also filters out-of-network replies and reposts. A post can be visible on your profile but still struggle to reach new people. So those viral engagement-point charts? Misleading. The code also doesn't establish a magic posting hour, a guaranteed 30-minute test, or a blanket penalty on external links. Likes aren't useless. Engagement counts are used elsewhere, but one reply doesn't simply equal ten likes. After going through this, I think most creators are optimizing for the wrong thing. X isn't just counting reactions. It's predicting which reactions are likely from each person, after deciding which posts are even eligible to reach them. That explains something important about the system, even if it doesn't tell me exactly why my own posts performed so differently. Your post isn't competing on likes alone. It first has to reach an audience the system thinks will care.

The honest opinion: If you want to get serious work done without interruption, fast and in one shot, move to $100 pro plan. The 5-hr limit in $20 plan, is barely getting work done. If you fire sone complex task prompt, it will suck up the whole 5-hr limit and you're waiting for your next 5-hr limit to finish it up. Yup, they said to fix the bugs and asked to use skill file for context, but even after that consumption of token is like water, even for Astra light use. The problem here is that you have been allocated the weekly limit and then you are not allowed to use it. The $20 plan is just for the small experiment work and if you're serious and want to build something, go for $100 plan. That will be much beneficial and you will be given more priority. This is not criticism but the experience what we have felt by using $20 plan.

UPI feels free. The payment rails aren’t. MDR is the fee sitting behind digital payments, and it’s back in India’s UPI debate. Here’s what MDR actually is, who pays it, where the money goes, and why it suddenly matters again. 👇

have an update to share that i’ve been keeping to myself for a while. i got laid off recently. it wasn’t something i expected, and honestly, it took me some time to accept the reality. but i’m ready to move forward, and i’m now looking for my next opportunity. i’m an AI Engineer with experience across GenAI, LLMs, agentic AI, backend systems, and building AI solutions end to end. i’m currently looking for Forward Deployed Engineer (FDE) / SDE roles, especially at AI startups where i can work closely with customers, understand real-world problems, and turn them into solutions that actually ship. also open to AI Engineer and Founding AI Engineer roles. i’m also open to freelance and GTM opportunities where i can help teams build, launch, and take AI products to market. if you’re hiring or know a team that’s hiring, i’d genuinely appreciate an intro. RTs & referrals would mean a lot. 🤍

Jio spent the last decade putting towers across India. Its next network may sit 650 km above them. Reliance Jio is reportedly targeting September 2027 for the first test launch of its own satellite network, and this is much bigger than putting one satellite into space. The plan: 🛰️ ~1,600 satellites in Low Earth Orbit 🌍 ~650 km above Earth 📡 broadband + cellular backhaul 📱 direct-to-device connectivity planned ⚡ roughly 100–150 Gbps capacity per satellite A few test satellites would go up first in September 2027 to validate the hardware, software and network. If those tests work: 2028: larger deployment begins 2030: ~400–450 satellites 2035: full constellation At full scale, the network is reportedly designed to provide around 4–4.8 Tbps of capacity over India. But the more interesting part is what this does to Jio itself. Jio already owns much of the terrestrial stack: fibre → towers → 4G/5G → devices/customers Now add: satellites → direct connectivity from space Remote villages, highways, islands or disaster-hit areas no longer necessarily need a nearby tower or fibre connection first. And for India, this could mean something strategically bigger: its first large-scale homegrown LEO broadband constellation, instead of depending entirely on foreign satellite networks. IN-SPACe has already found Jio's proposed architecture technically sound, with ISRO and DoT/WPC involved in the evaluation. Jio is now working through the international orbital and spectrum process with the ITU. One important unknown remains: Who builds and launches 1,600 satellites? Jio hasn't publicly named the manufacturing or launch partners yet. That may end up being one of the most interesting parts of this story. India's telecom race started on the ground. The next layer is being built in orbit.

Notion nearly died before most people had even heard of it. The idea was ambitious. The product kept breaking. Cash was disappearing. Instead of shipping more features, the founders eventually made the much harder call: start again. That reset became the Notion we know today. 🧵

India’s AI story is moving down the stack. TCS subsidiary HyperVault and partners plan to build up to ₹700B (~$7.4B) in a 1GW AI data center campus in Telangana. This isn’t another software launch. It’s compute infrastructure at scale. (1/4)🧵
