One /goal prompt to GPT 5.6 Sol and I got this. I didn't script, research, record, or edit. I did nothing.↗

Over the last month, I burned over $200k in tokens with gpt-5.6-sol. I built a lot. Instead of just reacting to the benchmarks, news, tweets, etc, I went a different route. This video is an overview of all the cool shit I built using the new model. Proper review coming soon™↗

Our DESIGNER is the number 3 GitHub contributor to private repos of all time let him cook↗

Combined @mattpocockuk's "grill me" skill with the concepts from Thariq's "Finding Your Unknowns" article into one agent skill: grill-for-unknowns. Your agent grills you to surface the unknowns FIRST, so you reach shared understanding before implementation. Works great with mode…↗

I built a software factory that actually works. Here's what I learned. Software factories have been all the rage these last few weeks. So I built one. Here's what I learned, how it works, and how you can build one in an afternoon. # My Goals It needed to be really simple, som…↗

Excited to share a major milestone from Mirai Labs. We've just published our latest research on state-of-the-art speculative decoding for LLM interactivity. Local LLM inference runs at batch size = 1, so speculative decoding must scale to large draft budgets. Existing factorize…↗

I have been thinking about whether to comment on this. Not clear if Gal is serious, rage baiting, etc. Whatever the case, it has spread enough in the design community that I want to share some thoughts. The psychological journey people go through with AI is quite fascinating to…↗

i think i've come around to AGENTS.md being one of the most important files your project can have and yet none of the major harnesses treat it like that↗

5.6 Sol is underhyped for general work Real work is not just a repo of markdown files and a git repo High level, high leverage work, whether you're a developer or not, spans crosses email, slack, multiple, documents, multiple tabs in my browser, and native software. It's no lo…↗

Matt Pocock just dropped an 18-minute talk at @aiDotEngineer on why software fundamentals matter more than ever in the AI age: 00:00 - Why specs-to-code produces garbage 04:36 - Grill Me: the skill that interrogates your plan before AI writes code 07:21 - Fix verbose AI with a u…↗

don't scroll jack. the users scroll should always map 1:1 with the content moving on the page. otherwise it feels like going from a highway to driving through mud. you can still do very cool transitions without jacking scroll (e.g. below)↗

The AI 2027 team has written a new scenario, AI 2040.↗

And you can also see our full showcase of how I built the game here: developers.openai.com/showcase/backr… This was not really a long-running project, more of a late-night idea. It truly didn't take that long; it built the vibes I wanted, and then we spent some time polishing it!↗

Workbench template to allow many GPT-5.6-Sols and Fables to coordinate as a team: workbench.md/templates/agen…↗

OpenAI just made GPT-5.6 available to everyone, so I wanted to answer the most burning question: Is GPT-5.6 better than Claude Fable 5? I tested both models across 6 real use cases: → Frontend design (5.6 has closed the gap) → Build a 3D Star Fox-style game → Edit and publish…↗

GPT 5.6 SOL IS HERE! How to run your personal + business life with GPT 5.6 Sol + Codex (full 49 min masterclass) We tested it for 30 days and the video it's the CLEAREST look at the FUTURE of work: Here's what's possible once you set it up: 1. Your inbox becomes cards every m…↗

my favorite thing about GPT 5.6 is that it's a fucking stellar researcher. you can now work at the level of your ideas. here's the entire prompt we used to get 5.6 Sol to post-train 5.6 Luna:↗

lil demo i made awhile back that got me very excited computer use + agent attention 👀 give the new chatgpt computer use a spin (now with live picture-in-picture too)↗

Introducing Ship OS: The agent-native way to ship software. Run your entire product development cycle in Notion, from customer feedback to a merged PR. Agents handle the triaging, routing, and summarizing. Your team handles the judgment calls. Set up Ship OS → …↗

On the Codex side, we’ve also got some major upgrades for developers today: - Edit files directly, both markdown and code - See and review PRs without leaving the app - Access Pro mode in Chats, and hand off to Codex - Use the all-new Ultra mode for your most demanding work - Ex…↗

You can now vibe code a language model. From a single prompt, GPT‑5.6 built the entire training pipeline and trained a model from scratch on my iMessage history. Locally on my Mac. It now generates replies in my writing style.↗

Introducing ChatGPT Work, a new agent in ChatGPT powered by Codex and GPT-5.6. It can take action across your apps and files, stay with a project for hours if needed, and turn a goal into finished work. It’s a whole new way to get work done.↗

BREAKING: GPT-5.6 Sol is out—AND Codex has been merged into ChatGPT Desktop as ChatGPT Codex. This combo model and desktop app harness are the gold-standard for knowledge work in AI. 5.6 is powerful, fast, half the price of Fable, and my default for almost everything. We’ve b…↗

obviously the best model we have ever produced, but also one of the best blog posts we have ever produced: openai.com/index/gpt-5-6/↗

1/ Last week at @aiDotEngineer, I presented the 2026 AI Engineering Survey: 1,000+ AI engineers on model selection, build vs. buy, who’s shipping with AI, and (of course) whether GPUs are going to space. This year, we ran it with @NotionHQ and @vercel. Some highlights 🧵↗

Give it a persona of a writer, a dataset of good examples, and most importantly, don't ask it to write the entire content at once, generate paragraph by paragraph with the agent.↗

LLMs don’t “have a personality.” They navigate a low-dimensional persona space. Roughly 4–19 axes explain ~70% of role variance. Construction: which region you want (who + how) Stabilization: keeping it there when the next user turn pulls elsewhere Most persona prompts only do…↗
