[Anthropic @AnthropicAI]

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.

The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.

Access to all other Claude models is not affected.

We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

@ViktorAkadra @HenryBushnell @TheAthleticFC Nailed it 🥅

AYSO is part of the solution! 🇺🇸 ⚽️

Players need to be afforded the opportunity to fall in love with the sport, and it starts with community-driven support.

[Henry Bushnell @HenryBushnell]

Why has the U.S., the richest and most successful sporting country in the world, never produced a men's soccer superstar?

In a word: culture.

(And a "broken" system.)

Codex is not just for coding anymore.

People are using GPT-5.5 to run farms, build iOS apps, design in Figma, launch businesses and automate workflows.

Mythos 5: We're Not Ready

- Mythos is extremely strong at SVG generation, producing highly detailed outputs that can take several minutes to create
- It is exceptionally good at creating graphics, games, websites, and complex UI designs
- Mythos is expected to set a new bar for web development and frontend generation, especially for design heavy workflows
- It can also generate surprisingly good music through code
- Anthropic's data suggests Mythos can achieve up to 52x training code speedups in certain optimization tasks, compared to roughly 4x for skilled humans on similar workloads
- Mythos is expected to be extremely expensive, the public version will likely be a nerfed version of the current testing model

Instead of watching an hour of Netflix, watch this 30-minute speech by the Head of Anthropic’s Coding Agents research team. It will teach you more about vibe coding than 100 paid courses.

It's over for... Adobe and Figma

Anthropic just dropped Claude Design.

Now you can talk to Claude and it turns your ideas into prototypes, slides, and one-pagers.

Prediction: In the AI age, taste will become even more important. When anyone can make anything, the big differentiator is what you choose to make.

OPENCLAW x OpenAI?!?

[Sam Altman @sama]

Peter Steinberger is joining OpenAI to drive the next generation of personal agents. He is a genius with a lot of amazing ideas about the future of very smart agents interacting with each other to do very useful things for people. We expect this will quickly become core to our product offerings.

OpenClaw will live in a foundation as an open source project that OpenAI will continue to support. The future is going to be extremely multi-agent and it's important to us to support open source as part of that.

[Elon Musk @elonmusk]

For those unaware, SpaceX has already shifted focus to building a self-growing city on the Moon, as we can potentially achieve that in less than 10 years, whereas Mars would take 20+ years.

The mission of SpaceX remains the same: extend consciousness and life as we know it to the stars.

It is only possible to travel to Mars when the planets align every 26 months (six month trip time), whereas we can launch to the Moon every 10 days (2 day trip time). This means we can iterate much faster to complete a Moon city than a Mars city.

That said, SpaceX will also strive to build a Mars city and begin doing so in about 5 to 7 years, but the overriding priority is securing the future of civilization and the Moon is faster.

Updates to ChatGPT:

You can now choose between “Auto”, “Fast”, and “Thinking” for GPT-5. Most users will want Auto, but the additional control will be useful for some people.

Rate limits are now 3,000 messages/week with GPT-5 Thinking, and then extra capacity on GPT-5 Thinking mini after that limit. Context limit for GPT-5 Thinking is 196k tokens. We may have to update rate limits over time depending on usage.

4o is back in the model picker for all paid users by default. If we ever do deprecate it, we will give plenty of notice. Paid users also now have a “Show additional models” toggle in ChatGPT web settings which will add models like o3, 4.1, and GPT-5 Thinking mini. 4.5 is only available to Pro users—it costs a lot of GPUs.

We are working on an update to GPT-5’s personality which should feel warmer than the current personality but not as annoying (to most users) as GPT-4o. However, one learning for us from the past few days is we really just need to get to a world with more per-user customization of model personality.
