Anthropic tests Jupiter-v1-p ahead of its developer conference

Anthropic has begun red teaming an internal build, Claude Jupiter V1, ahead of its May 6 Code with Claude event. Following last year’s Neptune-to-Claude 4 pattern, this may point to a near-term model announcement.

Grok 4.3 is now available on the API 👀

Users can now opt in to feature their Imagine templates publicly on Grok web.

> By enabling this feature, your template may be selected by xAI to appear in its publicly featured gallery. If your xAI account is associated with your X account, your X handle may be shown alongside the template.

Grok 4.3 got to the 7th spot on the Artificial Analysis Index, surpassing Muse Spark from Meta.

Notion is working on new triggers for custom AI Agents.

It will be possible to invoke agents from Discord, as well as via file changes on Google Drive.

OPENAI 🚨: Codex now has Pets! Pets are overlay avatars that live on your desktop.

8 predefined pets are available, and users can also use skills to generate custom pets!

Choose your Pokemon 👀

OpenAI made it easier to switch to Codex, as now you can import settings, plugins, agents, and project configuration from other tools.

At launch, Codex will also automatically detect new configs and suggest importing them.

OpenAI released Custom Dictionary feature for Codex and ChatGPT.

Users will be able to add their common phrases and abbreviations so they are properly recognized during voice dictation.

As a heavy voice-dictation user, this is the main feature that made me pay for a separate AI voice-dictation app.

Everything app 👀

GOOGLE 🚨: A new Gemini Flash model has been spotted on LM Arena.

Codex named him "Minty" 👀

Which Codex Pets did you make?

XAI 🚨: Voice cloning is now available on xAI Console in the US.

> Create a custom voice in less than 2 minutes or select from our library of 80+ voices across 28 languages to personalize your voice agents, audiobooks, video game characters, and more.

This also means we will see custom voices on Grok soon. I hope they won't be restricted to the US only.

Google is testing new Omni model for video generation ahead of I/O

GOOGLE I/O 🚨: A NEW OMNI MODEL IS BEING TESTED ON GEMINI FOR VIDEO GENERATION!

> "Start with an idea or try a template. Powered by Omni."

> This is a new leaked headline from the video generation tab on Gemini.

> Omni appears close to "Toucan", an internal name of the current video generation tool powered by Veo.

> If Google plans to release Gemini Omni for video generation, it would likely outperform Veo 3.1.

> If true (as it is still highly speculative), Gemini will be the first top-tier Omni model with video output!

Google I/O 2026 will be hot 🔥
