many startups just died today

Many developers have suspected for months that GPT-5.5 outperforms Claude Sonnet for coding. But SWE-Bench reported near-parity, and it made people question what they’d been seeing in practice. DeepSWE aligns more closely with that day-to-day experience: GPT-5.5 scores 70% versus Claude Sonnet at 32%. That difference is substantial. DeepSWE focuses on what tends to matter in real workflows: whether an agent can take a short behavioral prompt, locate the correct area of the codebase, and implement the change cleanly - without needing you to enumerate files, modules, and functions. SWE-Bench often fails to capture that, due to dataset contamination and weaker verification. deepswe.datacurve.ai/blog

I just cancelled my Claude account. I've been using codex, and haven't used Claude in several weeks.

Introducing Daybreak: frontier AI for cyber defenders. Daybreak brings together the most capable OpenAI models, Codex, and our security partners to accelerate cyber defense and continuously secure software. A step toward a future where security teams can move at the speed defense demands.

this is cursor team kit: a plugin for some skills we use to build cursor at cursor skills for verifying changes, driving local tools, and shipping reviewable PRs cursor.com/marketplace/curso…

Pets. Now in Codex. Use /pet to wake your pet.

After trying out a bunch of tools, skills, and the vanilla way of doing it, I’ve realized that, honestly, AI is pretty bad at writing tests.

Bro! Huge!!!!!!

opencode 1.3.0 will no longer autoload the claude max plugin we did our best to convince anthropic to support developer choice but they sent lawyers it's your right to access services however you wish but it is also their right to block whoever they want we can't maintain an official plugin so it's been removed from github and marked deprecated on npm appreciate our partners at openai, github and gitlab who are going the other direction and supporting developer freedom

since everyone already knows, i’m joining @opencode here's a demo of a thing im working on: async subagents / background agents should this exist? tell me what you’d use it for

This is huge

After months testing AI terminal CLIs, OpenCode won for speed, simplicity, and community vibe. Claude Code had hype but felt clunky. Gemini CLI was the hardest one: random HTTP errors, slower, plus rough UI responsiveness.

I can't believe someone would just steal from Anthropic like this. The millions of man-hours Anthropic spent hand-writing code, text, art, books, etc. to generate enough data for training must be taken into consideration here. Where is the respect for IP?

Neovim is so good now that I gave up a near two-decade love of TextMate with gusto! (After a few days of swearing). Amazing work.

GML-5 is really good. Call me impressed

I think I'm starting to understand the appeal of gen AI. It makes people think like they are winning at some game while the game they are playing is actually the wrong one. Just like gambling. Casino always wins.

started work on something complicated - instinct is to go write some code and think through it let me try it differently and use the LLM to create a plan first it just doesn't work when i don't really know what we need to build thinking through by typing is still important

AI can make work faster, but a fear is that relying on it may make it harder to learn new skills on the job. We ran an experiment with software engineers to learn more. Coding with AI led to a decrease in mastery—but this depended on how people used it. anthropic.com/research/AI-as…

#AI fatigue is real...
