Google prepares new Ultra mode for AI Studio Build

GOOGLE 🔥: A new Ultra mode has been spotted in development on Google AI Studio Build.

> "Build with advanced skills and tools," its description says.

> This new mode appears alongside Plan, Build, and the previously discovered Security review mode.

There is no sign that Ultra mode will require an Ultra subscription, or which tools and skills it will use. These new modes are likely being developed to work with Gemini 4 Argon.

How Sabi's brain-reading cap turns thoughts into text

Sabi is developing a noninvasive EEG cap that decodes internal speech into text. Using custom non-contact sensors and a neural model trained on large in-house datasets, it aims to make brain-to-computer input practical for daily use.

Microsoft launches Decision-1 model in Foundry

MICROSOFT 🔥: A new Microsoft-Decision-1 model for fast decision-making is now available on Microsoft Foundry.

Microsoft-Decision-1 was post-trained on Qwen3.5-9B for fast, single-pass decision scoring. Later, Microsoft is planning to rebase it on other models, including MAI and OpenAI models.

> "Microsoft-Decision-1 achieved the highest accuracy in our 36-benchmark comparison, spanning nearly 150,000 questions across benchmarks kept blind from training."

> "4.5 times quicker than Quyet-1.0-Large, the runner-up, and 35 times quicker than GPT-6 Sol."

> "We’re already testing it across Microsoft for everything from incident response and quality control to scientific discovery."

Everyone is testing 💪👀

Gemini 4 Argon hints emerge as Google tests Carbon checkpoint

Google has added new references to the Gemini 4 Argon model in Antigravity, with low, medium, and high reasoning efforts.

> Gemini web now also shows low, medium, and high reasoning efforts for all models, unifying the reasoning selector across tools.

> Business Insider recently reported that Google employees are already testing the next Gemini 4 checkpoint, called "Carbon," internally, and it performs at the Opus 5.5 level on coding tasks.

> The internal coding tool "Jetsky" referenced in the article is also an internal name for Antigravity (not the IDE version).

Ultrasoon? 👀

OpenAI lists new gpt-rosalind-discovery model in docs

OpenAI’s pricing page now lists unannounced gpt-rosalind-discovery beside gpt-rosalind-research at identical rates. The move suggests a broader Rosalind family, likely aimed at biology and drug discovery under trusted access.

Anthropic might be developing its own voice models

ANTHROPIC 🔥: A hidden Voice tab labeled as "Preview" suggests that Claude may offer an upgraded voice experience.

It is still unclear whether Anthropic is developing its own voice models, but a new option to share voice data for training has recently appeared in Claude's mobile apps.

I bet that for Anthropic, having their own voice models is quite important in case they want to continue releasing solutions for "vibe coders."

Or if they want to ship a proactive assistant 👀

ICYMI 👀: Codex can now use a reset on its own when users explicitly ask it to do so.

> "Allow Codex to use resets - Give Codex the ability to use a reset when you explicitly request it during a conversation and your current limit has 10% or less remaining. Resets are never used automatically."

This setting is placed in the Usage & billing section.
