BREAKING 🔥: GPT-6 Astra has been officially announced and will roll out in the coming days.

> Astra was pre-trained on more than 100,000 GPUs at Stargate, and GPT-5.6 Sol has been helping supervise its training.

> "Across the plans, Astra will be included in the normal usage allocation, and you will be able to use 100% of it for Astra."

AGI? 👀

Stunning 👀👀👀

OPENAI 🔥: Astra scored 63% on ARC-AGI-3 with a standard harness.

> GPT-6 Astra surpasses the human baseline in action efficiency on ARC-AGI-3. It used fewer actions than the median tested human on 96% of levels.

> A key behavior observed in GPT-6 Astra was its ability to turn unfamiliar environments into compact symbolic world models. It represented game mechanics as logical rules and developed its own domain-specific language shorthand to track state and plan actions.

Google announced a new Google Labs experiment called "Play with Putty", available via a waitlist for US users.

> Play with Putty is a collaborative vibe coding tool that lets you build tools and websites together in real time.

OpenAI announced Defense Factory, a new continuous defense concept.

"Defender's window" is the gap between the cyber capabilities of open-weight models and the current security level.

Without continuous defense practices that rely on frontier models, this gap will close, enabling malicious actors to freely abuse vulnerable systems.

> "Agents can now conduct long-running cyber operations by abusing increasingly available open-weight models. In response, at OpenAI we’re building a Defense Factory. An automated defense operation to find, validate, and fix vulnerabilities continuously."

> "Defenders have two structural advantages. They can give agents direct access to their code and use frontier models to get a head start over attackers abusing broadly available open-weight models."

What does it mean?

“Everything that makes it successful is exactly what makes it dangerous.”

Internet won't be safe anymore 🤖
