REBUILD

Physical job by day. Building an AI workspace by night.
Documenting every step until it pays for my time.

[REBUILD @RebuildDaily]

@ChatGPT Intelligent UI: more visual answers. As someone who checks his project at 2am after 11.5 hours on a construction site, "fast and visual" beats "long and smart" every time.

@OpenAIDevs @coreyching Plugins for ChatGPT is exactly the kind of thing a night-shift builder like me needs.

I work 11.5 hours on a construction site, then build until 2am. Anything that saves me 20 minutes a night is worth learning.

What's the easiest first plugin for someone with no team?

[REBUILD @RebuildDaily]

@leevalueroach The other side of this: I work a physical job, 11.5 hours a day on a construction site. AI can't carry a block or plaster a wall (yet).

But I'm using the nights to learn it anyway. Better to be the guy who runs the robot than the guy replaced by it.

[REBUILD @RebuildDaily]

@Leigh_Phillips I'm the mud. Six days a week, 11.5 hours on a construction site: facades, concrete, bricklaying, plastering.

At night I learn to build with AI until 2am.

My bet: the future isn't "trades vs AI". It's trades who can use AI.

[REBUILD @RebuildDaily]

Nobody on my construction site knows what I'm building.

They only know I'm building something.

Six days a week, 11.5 hours a day, I do whatever the site needs. Facades. Concrete work. Bricklaying. Plastering. Painting. Some days I carry 25 kg blocks up a scaffold.

I know almost every part of this job. And some days I'm so tired of it.

Then I go home, open a laptop, and work until 2am. Some nights I fall asleep on the keyboard.

No team. No investors. Only my belief in myself.

My coworkers don't know what I'm creating. This account is the only place I talk about it.

Why do I do it? One reason.

I never want my future kids to work as hard as I do.

Last week I looked up the robots coming for my job. One lays 500 blocks an hour. Fine. But none of them can do what I do: all of it, every day. So I'm learning to build with AI.

I'm documenting every step here until it starts paying for my time.

If you're also building something in secret, say hi 👇

[REBUILD @RebuildDaily]

I've carried blocks up scaffolds for years.

So I checked who is coming for my job.

> hadrian x · lays up to 500 blocks an hour
> fieldprinter · prints the floor plan, 75% less layout time
> jaibot · drills ceilings 2x faster, nobody works overhead
> spot · walks the site alone, 80% less inspection time
> rebar robots · tie steel 2-3x faster than by hand

and that's the funny part:

they're not coming for the skilled work.

they're coming for the jobs that wreck your back.

nobody on site is going to miss those.

[REBUILD @RebuildDaily]

@tonysimons_ Early access without knowing it is the best kind.

Custodian by day, agents by night. I'm the construction version of your story: Mon to Sat, 11.5 hours on site, then a laptop until 2am.

Following your journey 🤝

[REBUILD @RebuildDaily]

Cheaper and faster means something different when your build time is what's left after an 11.5-hour shift on a construction site. Cheap models are what let night-shift builders actually ship.

[ClaudeDevs @ClaudeDevs]

Haiku 5.5 is now available in the Claude Platform and Claude Code. On average, it costs around 75% less to run than Haiku 4.5.

It pairs well with Opus 5.5 or Sonnet 5.5 as a subagent. Use it for high-volume, cost-sensitive tasks like summaries, compactions, or database queries.

[REBUILD @RebuildDaily]

Genuine question: when a model proves something new in math, who checks the proof at 2am? Asking as the guy who checks his own agent's code at that hour.

[Tibo @thsottiaux]

Completely unrelated to the rest of the ships today, but our models did solve some important math problems and the team documented it in the following blogpost. Remarkable new era of scientific progress.

[REBUILD @RebuildDaily]

@thsottiaux New era of scientific progress. Meanwhile my scientific progress today: carried 25 kg blocks for 11.5 hours, then asked a model to explain a stack trace at 2am. We're all contributing in our own way.

[REBUILD @RebuildDaily]

@OpenAI Cool, but can it figure out how many 25 kg blocks fit on one pallet without me counting them? Asking for a scaffold."

[REBUILD @RebuildDaily]

A model proving new math overnight. Meanwhile I spend my nights asking mine to rename a variable. Respect."

[OpenAI @OpenAI]

We’re releasing a broad range of new mathematical results produced by an internal frontier model.

We’ve been consulting with the independent Advisory Group on Mathematics and Artificial Intelligence at the Institute for Advanced Study, and we have drawn on their advice and public recommendations to inform how we release these results.

Cloud sessions keep running when you close your laptop.

For someone on a scaffold 11.5 hours a day, that's the whole point.

One-time bonus credit expires tomorrow: run /claim-credit in Claude Code.

[ClaudeDevs @ClaudeDevs]

Cloud sessions run Claude Code on a fresh VM for each task, so you can start several at once and they keep going when you close your laptop.

We wrote a field guide with seven workflows that suit them, plus how to connect GitHub on the first try.

@OpenAIDevs Finally, a rate limit I can relate to.
Mine: 11.5 hours on a scaffold, then 2am laptop. Still can't unlock Tier 5.

[REBUILD @RebuildDaily]

@testingcatalog I carry blocks on a scaffold all day. At night my agent logs into things I don't have time for.
First thing I'd ask AgentID: can I get a badge for it too? My foreman has one. 😅

[REBUILD @RebuildDaily]

@ClaudeDevs "Keeps going when you close your laptop" hits different when your laptop closes at 5:30am because a scaffold is waiting.

Night shift: I brief the agent. Day shift: I carry blocks while it builds. Evening: I review the diff.

First time my side project has a second worker.

[REBUILD @RebuildDaily]

@claudeai I'm not a developer, I work construction. But I notice the pattern: every update is less "new magic" and more "it breaks less."

That's exactly when a tool becomes worth trusting.

[REBUILD @RebuildDaily]

@Joshua_WD Happy to consult. My rate is one robot that carries cement bags and doesn't complain about Mondays.

[REBUILD @RebuildDaily]

https://t.co/mp1pipvBRM

[REBUILD @RebuildDaily]

@Joshua_WD Honestly, every job on site is hard. Everyone does what they learned to do.

I wouldn't pick one robot. I'd take any of them that makes one task easier. Nobody here wants to be replaced. We just want the work to hurt less.

[REBUILD @RebuildDaily]

@aistasiia The split matters more than the price. Fast model for routine edits, strongest model only where reasoning decides the outcome. That's how I'd budget a night-time workflow with a couple of hours to spare.

[REBUILD @RebuildDaily]

@MikeDrucker On site we'd call that a very expensive way to hold a door open.
