Inspired directly by Bennett, I’m working on a similar solution to the 8sleep mattress
Will release a working model within 48 hours, completely open-source
Reverse-engineering the Whoop 5.0 to work without a subscription in 24 hours.
Starting now.

minor update 28 hours in
we got a local app server, schedule editor, comfort-level display, alarm config, hot flash flow, sleep report UI, Autopilot recap/profile, and bridge setup courtesy of ninesleep/OpenSleep
still buggy, UI needs lots of love but it works!

One idea i have about the dead internet theory is that all platforms will pivot to prioritizing paid subs for users via better features because advertisers will slowly begin running ineffective ads cause the real users on any given platform will be outnumbered by bots 10/1

Reminded I am still so far behind in AI adoption. Learned a ton talking to @jameshalldon and Co. about how to use, and be free of, frontier models, and got to see how people are using AI to enhance and express themselves while solving problems at @AIPSummit

GPT-5.5 is going to have a party for itself. it chose 5/5 at 5:55 pm for the date and time.
if you'd like to come, let us know here: luma.com/5.5
codex will help the team pick people from the replies. 5.5 had some good ideas/requests for the party, which we'll do.

rediscovering making friends from first principles
The IRL connection economy is a $400B market.
And companies are racing to own it.
In the last 6 months, $800M in capital was deployed on "IRL" bets.
@Tinder invested $60M into a new Events feature for connecting matches in-person. They're pivoting to IRL and offering experiences such as speakeasies, raves, and pottery classes.
@222place: raised a $10.1M Series A to curate blind social experiences for Gen Z. Personality-matched groups sent to hyperlocal nightlife events.
@JagermeisterUSA launched BestNightsVC - the only venture fund in the world dedicated solely to nightlife and IRL connection. 16 portfolio companies across 4 continents.
@timeleft: dinner with 5 strangers, every Wednesday. €18M ARR. 6,500 dinners/week across 200 cities.
Dion: members-only social app where the first move is buying someone a real drink, redeemed IRL. 10K members, 30K on the waitlist founded by @revekkapal.
Pie: Bonobos founder @dunn built an IRL friendship app. $24M raised. 130K MAU.
@weroad_official: group trips for 20-30 year olds who don't know each other beforehand. $150M valuation.
Matchbox: is an algorithm-powered matching platform for IRL events and has powered over 100,000 connections. founded by @liamjmcgregor (prev @MarriagePact)
New dating apps like Known @Celesteamadon, Cerca @MylesCerca, and Ditto @AllenWangzian are aiming to improve connection amongst young people.
Billion-dollar companies are paying $$$ for community and events leads:
- @AnthropicAI: Marketing Events Manager ($255k)
- @tryramp: Community Manager ($223k)
- @tryramp: Events & Culture Manager ($181k)
- @duolingo: Senior Community Manager ($193k)
- @NotionHQ: Community Programs Lead
Everyone knows the more time we spend online, the more valuable real-life connection becomes.
The question isn't whether IRL wins.
It's who facilitates it best.

Have you tried the new local model? It's Gemma-4-31B-IT-NVFP4. It's literally Bonsai-8B-gguf. It's on Qwopus3.5-27B-v3-GGUF. It's Nemotron-Cascade-2-30B-A3B. It's literally Qwen3.5-27B-Claude-4.6-Opus-Reasoning-Distilled. You can probably find it on Trinity-Large-Thinking. Dude it's Qwopus3.5-9B-v3-GGUF. It's a gpt-oss-puzzle-88B original. It's on Qwen3.5-35B-A3B-APEX-GGUF. You can watch it on context-1. You can go to LFM2.5-350M and watch it. Log onto Bonsai-8B-mlx-1bit right now. Go to zeta-2. Dive into Qwen3-Coder-Next. You can Llama-3.3-70B-Instruct it. It's on Voxtral-4B-TTS-2603. Qianfan-OCR has it for you. gemma-4-26B-A4B-it has it for you.
