AI Engineer

The 2026 World's Fair is completely sold out 🫡 ✅ The largest AI industry expo on earth ✅ Sold out on Leadership track for CTOs & VP AI's ✅ Sold out on Workshops tomorrow ✅ Sold out on ALL late bird tickets 🙌 65 side events still FREE all over SF (see website) What we will never sell out: Our commitment to publishing all the best AI engineering content for free online on YouTube. We have now opened limited overflow tickets for our expo and engineering tix — no seating guaranteed, sessions are first come first served. If you ARE one of our attendees, DO come down to Moscone for New Engineer Orientation tonight from 5p-9p to meet new friends and skip the morning crush for tomorrow. We expect EXTREMELY heavy last minute registration and need your help to load balance across days. Please give your speakers and sponsors all the love for all the effort they are putting into making this the greatest show we have ever done!

DROP EVERYTHING The first panel from the Local AI Summit at AIEWF is now live “State of the Union: Why Local, Why Now” Featuring leaders from NVIDIA, Roboflow, Osmantic, Forward Future, and EXO Labs

"I think it's important for people to understand how code works." Geoffrey Litt's Design Eng track keynote is live now: youtube.com/watch?v=WkBPX-… Thank you @NotionHQ for supporting his incredible work and thank you Geoff for kicking off WF26 for our Design Engineers!

Didn't expect to end up playing drums at @aiDotEngineer world's fair and jam with @swyx singing and @johncodes on the bass. Great vibes though, thanks guys. Had not played in a while...tempted to buy a drumkit again

@Harshit_stwt agree

Who Exactly Is an AI Engineer? The AI Engineer sits at the intersection of software engineering, machine learning, and product. *Builds LLM-powered apps & agents *Designs RAG & retrieval pipelines *Owns cost, latency & reliability *Deploys with Docker, CI/CD, cloud

@manuelnavid @trylatitude prescribe the pills to nonbelievers!!

The @aiDotEngineer world forum last week was great. Hard to find places like these were everyone is in the same wavelength Applying all the learnings to @trylatitude as we speak!!

At @aiDotEngineer in San Francisco, I asked @dkundel what confidential, never-before-announced 🤐 plans there are for @openai Codex:

At AI Engineer Europe, two talks gave opposite advice. Zechner: read every f***ing line. Lopopolo: code is free, delete your IDE. Opposite advice. Standing ovations for both. @altryne built a framework on the ride home. youtube.com/watch?v=ZpK5PW… The Z/L Continuum is real but the framing was wrong. It's not about the person. It's about the task. Meanwhile, the data: 861% increase in code deletion per PR. 242% increase in incidents. Bugs per developer up 6x from 2025. 31% of PRs merged with no review at all. Karpathy says: "It's never felt so tempting to stop looking at code at all — but don't do this in production." Maybe not every line in 2026 needs your eyes. Every system still needs your judgment.

@coreycoto concerning

I'm beginning to think OpenAI forgot to unpack the Codex reset button after @aiDotEngineer

As we build tools that scale alongside rapid AI advancements, platform design must evolve to let the models do their best work. @kevinhou22 on the evolution of @Antigravity at @aiDotEngineer.

The AI Engineer World's Fair by @aiDotEngineer is a great conference I attended a couple years ago. I couldn't make it this year but wanted to see which talks were good. They've started posting the talks on YouTube so I had Codex/GPT5.5 build me a ranked list of most popular talks by views per day. I have to remind myself that these tasks to scrape some data to help some decision is trivial for coding agents to do now. Here's the post showing how this was done: lawrencewu.net/posts/2026-07-… These are the top 5 talks so far (out of 77 posted): 1. What do we build now? - Theo Browne, @t3dotgg Views: 25,835 Views/day: 25,835.0 youtube.com/watch?v=xUnRQ9… 2. Field Guide to Fable - Thariq Shihipar @trq212, Anthropic Views: 47,730 Views/day: 15,910.0 youtube.com/watch?v=9fubhl… 3. Building Great Agent Skills: The Missing Manual - Matt Pocock @mattpocockuk Views: 93,712 Views/day: 9,371.2 youtube.com/watch?v=UNzCG3… 4. The Future Is Domain-Specific Agents - Justin Schroeder, StandardAgents Views: 28,792 Views/day: 2,879.2 youtube.com/watch?v=spNAUE… 5. Building an ACP-Compatible Agent Live - Bennet Fenner, Zed Views: 2,533 Views/day: 2,533.0 youtube.com/watch?v=HsxQIC…

@PYacobelli64537 @OpenAI @romainhuet @embirico @steipete 🙄

@aiDotEngineer @OpenAI @romainhuet @embirico @steipete I'd hardly call this the 'Golden Age', most AI systems are still fairly brittle and unstable for me to classify this as the Golden Age. Admittedly, I haven't watched the video yet, so I am basing my argument solely on the headline...

🆕 Congrats to @OpenAI on the highly anticipated launch of GPT 5.6 Sol, Terra, and Luna! youtu.be/pMggiOb18tc Here's @romainhuet, @embirico, and @steipete on why this is the dawn of the Golden Age of AI Engineering:

The product framing from OpenAI: models now ship every 6 weeks. GPT 5.6 on Cerebras runs at 750 tokens per second — a substantial PR in 10 seconds. 2025 was token maxing. 2026 is value maxing.

Three constraints, in order: Tokens: fixed. Compute: fixed by test boxes (agents run tests on a separate machine while you continue work) Attention: can't add more. "The most important skill today is deciding where to spend it."

In January, juggling 10 terminal windows felt like peak productivity. By April it felt silly. @steipete, @embirico, and @romainhuet on what actually changed. youtube.com/watch?v=pMggiO…

@bradwmorris if thats unhinged u aint ready for the tie dye @headinthebox youtu.be/-CnA2lGfymY

good mental model, hadn't thought about it this way before - seems obvious early iphone apps had to 'earn permission' by looking familiar. fake bookshelf, fake paper pages, fake compass etc - until users were bridged to just being more comfortable with new form factor we're currently in this same skeuomorphic phase with ai + software - trying to contort stuff to fit old shapes how many startups are actually just an .md file? @theo at @aiDotEngineer youtu.be/xUnRQ9vLXxo?si… also appreciate that AIE platforms the more unhinged speakers - an that theo used the ghetto slide deck, ty ty

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 ubiquitous language 09:45 - TDD is your AI's speed limit 12:35 - Deep modules: the codebase structure AI thrives in 15:04 - Design the interface, delegate the implementation These 18 minutes of software design fundamentals will replace 20 paid AI coding courses. Watch it, then read the guide on how to make a company AI-native below.

Thariq Shihipar explains the real mindset shift from coding agents: the old tradeoff triangle is breaking. "One of my favorite parts of Anthropic is that we believe that tradeoffs are not real" "What if you just did all of it?" "What if you forced reality to show you the tradeoff?" "The math of Claude and Fable really changes how you think about tradeoffs" "Good, fast, cheap. Now it's pick three" "The only way to prove that agents work is to do the best work of our lives faster than ever before" This is the operator edge of AI coding. Most teams still pre-negotiate with reality. They cut scope before the first attempt. Agents make it rational to try the unreasonable version first, then let reality show which constraint is actually binding. That sounds like hype until you ship something in 4 hours that used to take weeks. - @trq212, Member of Technical Staff at @Anthropic, at @aiDotEngineer

You should be afraid of the amount of ransomware / social engineering we are all about to be flooded with. One of the more memorable @aiDotEngineer talks was @Steve_Yegge scaring all of us to set up code words with family members so we can verify who's who. We're about 6 months away from OSS reaching Mythos levels.

Great to see my Chess AI presentation at @aiDotEngineer Europe has been uploaded to YouTube! It was a lot of fun in London, and I'll most certainly be back next year... Shout out to @christophstock and my colleagues at @tngtech! - youtu.be/BqZrTdgBaPw

We brought a truck to circle the block outside @aiDotEngineer World's Fair blasting our own music video, plus a booth full of lightsabers and plushies. The orcs still couldn't get anyone to believe orchestration beats collaboration. Thanks for stopping by LG-17.
