[Riley Brown @rileybrown]

Today i'm Open Sourcing "Rilable"
The iOS app that builds Web apps and iOS Apps.

I built it with Fable 5 in 10 prompts.
(~ $210 in tokens on API pricing)

All apps are built with Claude Models, and every app spins up a sandbox (Exactly like Lovable) using @daytonaio. Database is @convex. The app allows you to build apps that have AI features for this it uses @vercel AI gateway, and iOS apps are using @chorus_agent iOS skill

[Andrej Karpathy @karpathy]

This is a super exciting release - Claude Fable 5 is the same underlying model as Mythos but with added safeguards. The benchmarks are great and it's SOTA on everything by a margin but I'll add that *qualitatively* also, this is a major-version-bump-deserving step change forward (imo of the same order as Claude 4.5 was in November), peaking especially for long problem-solving sessions on very difficult problems. You can give it a lot more ambitious tasks than what you're used to, the model "gets it" and it will just go, and it's never felt this tempting to stop looking at the code at all (but don't do this in prod!). The model still has quirks that people will run into and the safeguards are configured to be a little too trigger happy for launch, which can hopefully be tuned over time.

I feel a lot of things changing as working software increasingly comes out on a tap. The Jevon's paradox kicks in and I feel my own demand for software growing substantially. You can ask for anything - explainers, visualizers, dashboards, bespoke single-use apps (e.g. a full wandb that is hyper-specific just for your project), you can 10X your test suite, auto-optimize code, run giant research projects with custom HTML for the results, anything! "Free your mind" (Matrix ref). Really looking forward to all the things people build!

Wow Paper inside Codex is pretty wild.

[Riley Brown @rileybrown]

Wow Paper inside Codex is pretty wild.

Especially with my youtube thumbnail skill.

It can just pull thumbnails from YouTube or any site and place them on the board and i can explore concepts really quickly.

Every image is an element, and i'm using the built in gpt- image 2 model that's built into codex to mix and match.

AI 시대, 가장 가치 있는 개발자는 장인이면서 빌더인 사람이 될 것

- AI 코딩 도구의 확산으로 누구나 빌더(builder) 가 될 수 있게 되면서, 손으로 코드를 짜는 장인(artisan) 의 가치가 재조명되는 중

[Liquid AI @liquidai]

Training LFMs at scale means solving parallelism across every layer of the architecture. And not all layers are the same.

Our CTO Mathias Lechner (@mlech26l) sits down with Liquid's founding engineer Paul Pak (@paulpak__) to talk training infrastructure: Data, tensor, pipeline, expert, and context parallelism, and how they make context parallelism work across hybrid architectures with both attention and convolution operators.

Codex use-cases: “From software engineering and design to data analysis and operations, Codex is becoming an AI teammate instead of just an AI assistant.”

[John Bai @johnbai]

It's kinda crazy that you can just use multitask design mode to make a bunch of frontend UI changes, then ask for a shared link canvas with a recap of the changes in like 5 min

Codex와 함께 작업하는 개발자를 위한 2가지 품질 향상 개선 사항:

Codex 배경 에이전트는 이제 안정적인 픽셀 아이덴티콘을 가집니다.
같은 에이전트가 탭, 멘션, 대화 기록, 스레드 패널에 걸쳐 나타날 때, 한눈에 알아보기 쉬워집니다.

[OpenAI Developers @OpenAIDevs]

2 quality-of-life improvements for developers working with Codex today:

Codex background agents now have stable pixel identicons.

When the same agent shows up across tabs, mentions, transcripts, and the thread panel, it’s easier to recognize at a glance.

가족 에세이《나의아빠 광호에게》

사랑하는 사람을 향한 그리움이 한 권으로 남았다.
"이 책은 아빠를 먼저 떠나보낸 모든 딸들에게 보내는 작가의 위로이자 슬픔의 공감이며, 사랑하는 가족을 잘 떠나보내는 일은 슬픔을 감추는 것이 아니라 있는 그대로 받아들이고 표현하는 것임을 알려준다."
