We've received several questions about the Opus 5 FrontierCode results, where scores decline as reasoning effort increases. In fact, the behavior is expected under the benchmark design. FrontierCode evaluates merge-ability rather than correctness alone, incorporating criteria that reflect user experience.
One such verifier is a scope criterion, which penalizes modifications to the codebase beyond what the task requires. We observe this effect across all frontier models we evaluated, though it is most pronounced in Opus 5: at higher reasoning efforts, the model shows a stronger tendency to refactor code unprompted.
Building software by prompting agents without ever reading or editing the code directly isn't actually a new thing. It's just called being an engineering *manager*. We have decades of experience about how to be effective as engineering managers. It is a different skill, though.
Codex CLI 0.145.0 is out!
Highlights:
- Multi-agent V2 is now stable, with configurable sub-agent models, reasoning levels, and concurrency.
- Experimental paginated thread history adds efficient resume, occurrence search, persisted names, and memories.
- Audio inputs and tool outputs land, with streaming realtime V3 conversations.
- / import expanded to migrate Cursor and Claude Code settings, MCP servers, plugins, sessions, and memories.

Introducing Loupe, our latest privacy app for iOS. Discover what apps can learn about you just by reading data your iPhone already exposes, such as your languages, installed apps, device sensors, and much much more
Loupe is free, private, and open source. Give it a try 👇
Learn how to name your tasks in Swift Concurrency. The names show up in LLDB, Instruments lanes, and SwiftUI's .task modifier. One small string, much better debugging.

Apple updated its Human Interface Guidelines for Sheets on March 24, 2026 to add guidance for button placement in the toolbar.
"In iOS & iPadOS, the Cancel button belongs on the leading edge of the top toolbar."
Time to update my apps 🙂

@warpdotdev Could you also support horizontal tabs inside each vertical tab as in cmux? For each worktree I want to have a bunch of tabs: lazygit, codex… Yea, I can now have it using cmd+D, but this way they’re not visible
🚨 Critical Supply Chain Attack
LiteLLM (a core dependency for 100s of AI tools) was compromised in PyPI versions 1.82.7 and 1.82.8.
The malicious litellm_init.pth file runs on ANY Python startup, steals SSH keys, env vars, cloud creds, Kubernetes secrets, etc., then exfiltrates them.
It even tries to persist via systemd/K8s.
If you use LiteLLM, check immediately:
- Run: pip show litellm
- If version 1.82.7 or 1.82.8 -> uninstall + rotate ALL credentials NOW
- Pin to safe version: litellm<=1.82.6 (or latest clean release)
Also purge caches: pip cache purge

We partnered with @OpenAI to let you use your existing subscription. Sign in and access all the models in your subscription. No API keys, flat-rate pricing instead of per-token costs.
Here is how to enable this:
Some good tips in there, also A LOT of workarounds to fight Sonnet's post-training choice for rushing instead of being diligent and careful. With codex you can drop 90% of the charade. https://t.co/IuRx9AX8wR

Apple's JS-rendered docs leave AI tools staring at blank pages. I got tired of Claude writing broken SwiftUI code, so I built https://t.co/pb1UMcV8mC
Swap developer․apple․com → sosumi․ai in URLs to get clean, AI-readable Markdown. Or connect via MCP.
New in Xcode 26 Beta 7: Users can now log into their Claude account from Xcode.
Generate code and documentation, automatically fix errors, and create inline playgrounds using coding intelligence features in Xcode, powered by Claude Sonnet 4.
