A Perfect ARC-AGI-3 Score, Bulk Mac Buys, and Agents That Prompt Themselves
@ashpreetbedi reports that gpt-5.6 plus "learning machines" scored 100.00 on the ARC-AGI-3 public set, with a smaller Gemini model beating the human baseline using its notes. The rest of the feed belonged to practitioners wiring up self-running agents, alongside unverified reports of OpenAI bulk-buying Macs and a class action over Anthropic's Max pricing.
Quick Hits
- Learning beat memory on ARC-AGI-3, if the numbers hold. @ashpreetbedi says agents left to learn from each run, with no instructions, took gpt-5.6 to 100.00 on the public set, and gemini-3.7-flash scored 96.42 using gpt-5.6's notes, above the 95.4 human baseline. All self-reported by the author's team.
- Labs are allegedly eating the Mac supply. @jun_song relays @LuminaBench's claim that OpenAI bought tens of thousands of Mac minis and Mac Studios for RL and computer-use training, and that Anthropic is mass-renting Mac minis through AWS. Unconfirmed, but the scarcity story is circulating.
- Anthropic's "20x" is on trial. @kimmonismus details a proposed June class action alleging the $200 Max 20x plan delivers only around 2x the weekly usage of the $100 plan, since the multipliers apply per 5-hour session, not to undisclosed weekly caps. @emollick flags the same vendor-communication gap, complaining that labs leave it to users like @simonw to explain confusing modes such as ChatGPT Work.
- Judgment still isn't optional. @addyosmani's "Don't paste the AI, please" and @i2cjak's applause for @MattiaFiumara's data-first takedown of capacitor design myths both argue against outsourcing your thinking.
- A security alarm with no context. @onewayfunction amplifies @matthew_d_green's reply about industrial control systems ("We're so completely fucked"), though nothing in the thread says what set him off.
Agents that run while you sleep, and talk to each other
The clearest through-line across today's posts: stop prompting, start structuring. @0xSizer relays an Anthropic engineer's claim that "at Anthropic we don't write prompts anymore. We build loops and graphs," from a 30-minute walkthrough (surfaced via @hanakoxbt's course thread) where a shape drawn once on screen runs the work unattended. His argument: two operators spending identical tokens on the same Claude model can end the week in different economic classes, because the difference is the structure around the model.
@mattpocockuk says his AFK agent workflow "ended up being better than expected" and now beats his /implement-spec skill, a multi-agent implementer that researches the codebase in a subagent, implements tickets with maximum concurrency, reviews against the spec, and cleans up worktrees. He still calls /implement-spec worthwhile "while tokens are cheap" and plans to publish the AFK workflow after his holiday.
The infrastructure version comes from @petergostev: get long-running agents off your laptop and onto an always-on remote Linux box, "go into debt if you have to." His earlier setup post described a roughly $3,000 Asus NUC (Ultra 7, 96GB RAM, 2TB SSD) that kept his agents alive during a week of travel, using Codex's remote support for task creation and Tailscale for file moves.
Once you run several agents, coordination becomes the product. @herdrdev noticed users installing herdr on Grok bots and shipped Shepherd, "the bot that herds your bots," as a ready template. @theaaron's recipe installs CLI agents on the Grok Bot VM, lets herdr manage those sessions, and reserves Grok Bot for coordination so its rate limits stretch further. @_alejandroao highlights @RiverAi7z's variation: run Grok, Claude Opus, and Codex in parallel, have them review each other's proposals, and let a main model converge, which reportedly removes most copy-pasting between models.
Token discipline: make agents ship instead of doing paperwork
Two posts converge on the same pathology, agents generating process instead of progress. @v4rvl's new skill targets GPT models' fondness (Sol especially) for hashes, locks, receipts, and status files, which produces redone work and refusals over stale markers. The fix classifies every action as implementation, validation, or bookkeeping, and skips the third; stale metadata is never a reason to redo finished work, while tests and benchmarks stay mandatory. He says it took his GPT experience "from 3 to 8" and cut token burn.
@cullend claims a "stupid little bit of text" cut Codex's token usage by about 30% with evals only improving, then extrapolates that OpenAI-wide adoption would save 10,000-20,000 tons of CO2 a day. The CO2 figure is back-of-envelope math, but the direction matches @v4rvl's. The counterweight is @_lopopolo, who uses zero skills in his repos at all, a useful reminder that the skills economy (archify, Shepherd, /implement-spec) is opt-in, not consensus.
The compute squeeze, from lab fleets to one desk-side Spark
The detail behind the Mac rumor matters. Per @LuminaBench, OpenAI's purchases target RL and computer-use training, Anthropic is renting Mac minis through AWS, and "every decent piece of compute is just going to get eaten by AI labs." @jun_song draws two conclusions: the compute shortage is serious, and Apple Silicon is actually solid for this workload. Meanwhile @txmed

ok, this week I started really enjoying GPT models. Finally, made a fucking skill to prevent overengineering and invalidating work to validate receipts garbage. Experience went from 3 to 8. Furthermore, usage limits are quite insane, Sol as a coordinator, 20 luna worker at all times for lookahead review and implementations. Crazy stuff. finally, I am making more and more use of GPT 5.6. PRO, I used to give it updates, use it as a third view and drop in detailed prompt to steer the work. Lovely stuff. I am still figuring out how to use it properly, I noticed I can be connected to the terminal through that GPT session + there is a remote option as well, which seems insane. Let the session run, check up on it from the gym. What I need to figure out is can it actually message the running Codex (terminal) session. If it can, holy moly. That's amazing. Plus, this man keeps reseting usage limits (which now got really better btw!!!), I unfucked myself, ran more experiments and GPT is now my favorite model, dethroning Opus. Ultimately, it was me who was retarded. Will put more effort into figuring out how to make better use of both GPT, Claude and Grok, as a few days of focused experimentation really transformed my experience.
How to land your first AI consulting retainer
I finally decided to pull the trigger and set up a little local Linux box to run my agents on. The reason why I did this is that my MacBook Pro was completely dying under the strain of agents. I got Asus NUC 15 Pro, Ultra 7 255H CPU, 96GB of RAM, 2TB SSD. The whole thing was about $3000, but you can do it way cheaper too. My boy math is that it a Mac Studio could be as much as $10,000, so I'm practically making money. Codex has great Remote support for this set up, much smoother than I thought - I can create new tasks from my Codex mac app or from my phone - all feels pretty similar to how local tasks work. Then I use Tailscale to move any files around too, delightful. I'll leave it next to my router hidden away, no extra clutter around the house. Set up took a couple of hours, it took a bit of back & forth, but agents are pretty good at holding your hand during the setup. Inspired by a @theo video about moving to Linux, really not as scary as I thought. Sticker art by a wonderful London based artist Natalia Shaloshvili.
i love @grok @bot i do not love its rate limits here is a simple way to get more usage out of it: install your coding agents on Grok Bot's virtual machine Codex, Cursor, Grok Build, Antigravity, etc then, install @herdrdev to manage those CLI agent sessions now give Grok Bot a rule: use Herdr + CLI agents for anything more than conversational tasks your rate limits for Grok Bot will only be coordination and prompting, rather than the coding tasks themselves and you can use those @cursor_ai and Grok Build limits AND crank on Grok Bot without getting rate limited as fast

Loops and Graphs: how to stop babysitting agents and only approve the last step (full course)
I'm trying out an /implement-spec skill Essentially a multi-agent implementer that: - Takes in a spec and tickets - Does codebase research in a subagent - Implements all the tickets in subagents with maximum concurrency - Reviews the final code against the spec - Cleans up all worktrees Should be able to smash out huge chunks of work autonomously with minimal supervision. https://t.co/lTmPYXkUx7
Software Factories: Emerging Architectures and Why Frontier Labs Should Care
🚨 OpenAI are now contributing to the Mac shortage OpenAI have apparently bought tens of thousands of Mac minis + Mac Studios for RL and computer use training Anthropic are mass renting Mac minis through AWS too At this point every decent piece of compute is just going to get eaten by AI labs, looks like a good time to buy
Running a Software Factory Efficiently at Uber Scale
@valkenburgh Oh god the industrial control systems. We’re so completely fucked.
I've seen this countless times: placing different sized capacitors to suppress different frequency noise. In practice this causes more harm than it does any good, for the science behind this, check out https://t.co/U3hGps3fes. This is just one of the myths floating around on how to design electronics, passed down by the older generation and actually taught in universities. Never accept anyone telling you on how to do electronics design without the data backing up the claims.
Here's my attempt at explaining what ChatGPT Work can actually do - it's a deeply confusing but extremely powerful tool with a whole lot of useful features that aren't available in regular ChatGPT https://t.co/QDVytAKmww https://t.co/E4oML5DpN3
分享一下我是怎么用 Herdr 的: Herdr 对我最大的价值,是让不同模型可以互相发送消息。 我会同时开 Grok、Claude Opus、Codex 等 Agent,让它们分别给方案,再互相评审一轮,最后让主模型汇总收敛。 相当于从减少了我在AI 之间复制粘贴,变成让 AI 自己讨论。 效果非常好。 https://t.co/xykXW9MgKD
We love the new OS Omarchy (from @dhh) and decided to build the last few days on a truly native Linux version of our game. We previously used Photon, but wanted to go true native. The latest build with some special support for Omarchy is now live on steam. This allows for full resizing, playing in tiles and more!
Today I learned : Claude’s $200 Max plan offers 20x Pro usage within the five-hour window, but its weekly limit is only about twice that of the $100 plan. Oh and btw: Tibo has confirmed that Codex really sees 5x more weekly usage. Anthropic strikes again
