We’ve written an FAQ to answer some of the questions we've received about watermarking.
In summary:
• We’re implementing watermarking to comply with the EU AI Act. Other major model developers have signed the same Code of Practice and will also be implementing watermarking;
• Our watermarking method doesn’t have any practical impact on the quality or content of Claude’s outputs;
• The difference between watermarked and un-watermarked text will not be distinguishable to readers;
• Nothing is added to the text and there are no hidden characters;
• Watermarking doesn’t require extra tokens, and will not be more expensive;
• Watermarks can’t be traced to a specific person, organization, or chat.

Previewing Ultrafast mode: GPT-5.6 Sol at up to 14x the speed.
Launching first in the OpenAI API to a select group of customers with expanded access to more businesses as capacity grows.
🚨 Gemini 3.7 Flash is likely to launch later today at reduced pricing of $0.75/Mtok in, $3.75/Mtok out
3.5 Pro is internally dead, with most teams now working on the scaled up Gemini 4, seen as a sort of last shot at a genuine frontier model lineup
Now in preview: The ChatGPT desktop app for Linux.
Use ChatGPT, ChatGPT Work, and Codex where you already work and build, with your projects and browser workflows on supported Linux systems.
We’re expanding our cybersecurity initiative Daybreak and introducing GPT-5.6-Cyber, a new model for advanced, authorized cybersecurity work.
As the threat landscape evolves, we’re putting frontier intelligence in the hands of trusted defenders before attackers can deploy offensive AI at scale.
to put ai progress in perspective:
9 months ago: most developers wrote code by hand
now: misaligned multi-agent swarm finding and collaborating on 0-days undetected (OpenAI/hugging face)
9 months in the future likely much crazier
I would love to help, but I don’t work at Anthropic.
It does seem odd that they would ban your account for using their harness with another model.
Anyone else in the same situation?
After evaluating one of our upcoming models, Astra, we're treating it as our first "critical" model for cybersecurity under our Preparedness Framework.
This is a scenario we've planned for, and we're putting additional controls in place to ensure Astra's further development happens safely and securely.
We're working hard to make Astra broadly available, and get its advanced cyber capabilities into the hands of defenders.

🚨 EXCLUSIVE: OpenAI are preparing to launch Astra imminently, targeting next week.
Their next major model, Astra is a new pretrain - the largest model OpenAI have trained since GPT-4.5. Their most recent dogfood checkpoint of the model, internally known as "mewfour", is the Release Candidate.
