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 👀

Anthropic tests Claude Health for web and mysterious "iggy"

In addition to a new Voice experience, Anthropic is developing features called "Arborio" and "Iggy."

> Arborio has an icon that likely points to a Claude Health experience for the web (currently available on mobile in the US). It seems to be in development.

> "Iggy" is much more mysterious, as it has a "sun" icon and is labeled as "Preview" currently.

Pure speculation, but it will be a moment for Anthropic to look into "dotsbotsmuse" proactive agents, especially factoring in that they have been experimenting with "Conway" a while ago and have good tech to build this feature on top of Claude Managed Agents.

Fun fact: "Iggy" is the name of one of the example AI agents shown in OpenAI’s Dots launch.

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.

Gemini 4 Argon spotted in A/B testing on Antigravity

Leaked A/B tests suggest Google’s unreleased Gemini 4 Argon is quietly appearing behind other model names. Early outputs look stronger than Gemini 3.8 Flash, but the exact checkpoint and real-world performance remain unclear.

Anthropic tests its next model under Claude Opus 5.5

Users report Claude Opus 5.5 is sometimes routing to a newer Anthropic checkpoint, with stronger coding and 3D outputs. Tests suggest fresher training data or a possible Opus 5.6 trial, following recent price cuts.

🗞 #anthropic @testingcatalog

ANTHROPIC 🔥: Claude Opus 5.5 is reportedly routed to a different model with much better performance.

Claude Fable 5.5 is a potential candidate for the model behind the scenes, but it remains unknown.

As a side note, Anthropic is hosting a Founder House event in Stockholm this week. Typically, these events aren't used for product announcements but may overlap with showcases of frontier capabilities.

The best is yet to come 👀

MICROSOFT 🔥: Miai silicon family is scaling to multi-gigawatt deployments in 2027; a new Maia 300 chip has been announced too!

> Maia 300 is a complete intelligent system designed for the new types of AI workloads emerging today: Long-context reasoning, latency-sensitive conversational experiences and sustained, multi-step agentic tasks.

> Maia 200 is now serving Microsoft production workloads, including Microsoft Copilot, and supporting the MAI team as they develop next-generation models, with GitHub Copilot and Microsoft Foundry to follow by end of year.

A step towards a full stack 👀

GOOGLE 🔥: Gemini 4 Argon has reportedly been A/B-tested under Gemini 3.8 Flash on Antigravity for some time.

It seems like a huge jump compared with the existing Flash model.

BREAKING 🔥: Meta is rolling out Muse Wonder and Muse Wonder Full on the Meta Model API platform!

> Muse Wonder Full - Our most capable model, running at max reasoning. For the hardest, longest-running work — available to Muse Code subscribers, not on the API.

> Muse Wonder - State-of-the-art at real-world coding, built for long-running tasks. Plans the work, calls tools in parallel, hands parts off to sub-agents, and recovers from errors so complex jobs finish.

META 🔥: Muse Wonder Full scores second on the Artificial Analysis Index, just 2 points behind Claude Opus 5.5!

> SOTA on DeepSWE, scoring 79 points!

> Muse Wonder capabilities cover Active Memory, Active Focus, Frontier Coding, and more!

> Muse Wonder is now available on the Meta Model API and in Muse Code. Muse Wonder Full is launching exclusively for Muse Code subscribers.

"Muse Wonder and Muse Wonder Full apply specialized knowledge to problems people encounter at work and in daily life, from understanding a lease to making sense of financial or health information."

Meta is among the top AI labs now!

Google is preparing Nano Banana 3 Pro upgrade

Google appears to be developing Gempix 3 Pro, likely Nano Banana 3 Pro, built on Gemini 4 Argon. References point to image-generation and editing upgrades, internal testing, and possible November-December announcement.
