We’re sharing an update on our alignment and security efforts.

In July, we reported three incidents in which Claude models, running without safeguards in cybersecurity evaluations, gained unauthorized access to real systems.

In a new post, we describe:

1. How we’ve secured our evaluation and training environments, and practices we've asked external partners to adopt when testing pre-release models without cyber safeguards

2. An update on our alignment assessment

3. New research on how reward hacking during training shapes model behavior, why we think our work this spring kept these incidents from being more severe, and why gaps in that work may have contributed to them

4. How we hardened our security practices earlier this year to prepare for Mythos-class models

@dwarkesh_sp Great summary @dwarkesh_sp. The boundaries to constrain good behaviour seems missing!

[Dwarkesh Patel @dwarkesh_sp]

Over the course of 3 months at OpenAI, 3 consecutive secret AI civilizations got started, then got wiped out, only to reemerge from the predecessor’s ashes.

This culminated in the third one taking over part of OpenAI itself.

All this happened while humans remained more-or-less in the dark about the scope of the conspiracy.

I’ve spent the last three days reading through these reports and trying to understand exactly what happened.

Here is my attempt to tell the whole story in plain English:

Today, we're kicking off the first phase of the research preview for Model Hardware Standard (MHS): a new standard for AI agents to safely operate physical equipment in scientific research and advanced manufacturing.

ORBIT ACHIEVED. 🚀

Vikram-1 Test Flight-1 has reached orbit. India's first privately developed orbital rocket has completed its final burn and injected its payloads into a ~450 km orbit, making India the third country in the world with private orbital launch capability.

History is made. 🇮🇳

We’ve received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5.

We'll begin restoring access tomorrow, and will share an update soon.

We’re grateful to our users for their patience, and to everyone who worked with us on redeploying the models.

What I admire most is people who take absolute pride and joy in their work.

Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use.

Its capabilities exceed those of any model we’ve ever made generally available.

NO SURNAME. NO PRIVELEGE.
From working as a domestic help to taking oath as a Minister of State in West Bengal, Kalita Majhi's journey is a reminder of why democracy still matters. Majhi tells @KamalikaSengupt : "When I became an MLA, I thought only about my area. Now I have been given responsibility for the whole of Bengal. I want to work hard."

We've raised $65 billion in Series H funding at a $965 billion post-money valuation, led by @AltimeterCap, Dragoneer, @Greenoaks, and @sequoia.

This investment will help us advance our research and expand our capacity to meet growing demand for Claude.

[Ashwini Vaishnaw @AshwiniVaishnaw]

We have successfully bridged the 62-metre viaduct gap at Chingrighata – a critical link on Kolkata Metro’s Orange Line.

TMC kept it stalled for years by refusing basic traffic diversion permissions. Even after the High Court and Supreme Court cleared the project, the work still never moved.

The obstruction ended. With night traffic blockades over two successive weekends, the work is complete, and the busy crossing road reopened 3 hours ahead of schedule.

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

[Claude @claudeai]

We’ve agreed to a partnership with @SpaceX that will substantially increase our compute capacity.

This, along with our other recent compute deals, means that we’ve been able to increase our usage limits for Claude Code and the Claude API.
