"Can AR-Embedded Visualizations Foster Appropriate Reliance on AI in Spatial Decision Making?"

We conducted an empirical study (N=32) comparing AR see-through vs. 2D minimap in time-critical, AI-assisted spatial tasks.

Key finding: Contrary to expectations, AR embedded visualizations led to greater over-reliance on AI — driven by perceptual challenges, proximity illusions, and heightened trust in "embodied" AI cues.

Yet AR still showed strengths in spatial mapping & egocentric reasoning.

Proud to contribute as second author alongside and am deeply grateful for the opportunity to collaborate with such a brilliant team.🙌 @CartonLiu

@antigravity why there is no permission control in antigravity ? at least we should have a default/full access/auto review

@thsottiaux Codex is perfect except this one

[Difan (Bobby) Jia @KeithMaxwell99]

@thsottiaux Subagent is still unusable. Please refer to how Claude code organize the subagent.

@thsottiaux The chat history now only seems to sync up to the first 50 messages, and the rest of the messages just disappear.

Best time for builders

[Sam Altman @sama]

you know what

all of these "which is better" polls are silly

use codex or claude code, whatever works best for you

i am grateful we live in a time with such amazing tools, and grateful there is a choice

[Difan (Bobby) Jia @KeithMaxwell99]

@twi_mar @KenPfeuffer @HansGellersen Great work!

[Xiaoan Liu @_seanliu]

just built an extension that auto-logs every paper you read, lets you organize them with tags, and attach links to your LLM chats for each paper

@thsottiaux for computeruse, it just take over my display window randomly (or is there any setting to fix which display i assigned to it)

[Sam Altman @sama]

Tim Cook is a legend.

I am very thankful for everything he has done and I am very thankful for Apple.

For AI-native:

In the future, setting menu should only be the fallback solution for an APP.

All settings and functions should be able to work/be modified in a CLI or Chat interface, directly or with a small artifact generated by AI.

Any (to c) apps letting the users jam in the setting menu should be discarded.

You can just build things! I love this gifts from @OpenAI. Thank you! @thsottiaux

[Finn Voorhees @finnvoorhees]

Okay this is *crazy*

An agent running entirely on iPad* that can control any app

[Difan (Bobby) Jia @KeithMaxwell99]

@thsottiaux Please make codex support pro model for pro user.

[Difan (Bobby) Jia @KeithMaxwell99]

plan to launch something for iphone ai agent.

hint: shortcut

Introducing Lovable General Tasks 🔥

You can now build way more than just apps:

→ Analyze data and generate PDF reports
→ Create marketing assets for your product
→ Build interactive pitch decks
→ Produce animated launch videos

I am personally so excited about this. Lovable is becoming the entire startup stack in one interface.

Build your product, design your pitch deck, create your launch video. All in the same place.

The team has been relentless. We're just getting started.
