Fable 5 is back.

[Anthropic @AnthropicAI]

Claude Fable 5 will be available again globally tomorrow.

After a series of productive conversations with the US government, we're redeploying the model with a new set of classifiers to target and block more cybersecurity tasks. In the near term, some routine tasks like coding and debugging will fall back to Opus 4.8. We’ll continue to refine these classifiers over the coming weeks to reduce false positives and better distinguish genuine misuse from legitimate requests.

We’ve also begun drafting a consensus framework—with Amazon, Microsoft, Google, and other Glasswing partners—for assessing the severity of AI jailbreaks and how AI developers should respond to them. We invite other industry partners and model providers to join us in this effort.

Finally, we’re scaling up our collaboration with the US government on model testing and safeguards. This will include pre-release access to models and safeguards for evaluation, information sharing on jailbreaks and misuse, and dedicated resources for joint research.

Thank you to our users for your patience, and to our partners across the government, industry, and the research community who worked alongside us to make Fable 5 available again.

[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.

[Claude @claudeai]

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.

[Penguin @PenguinWeb3]

I found the weirdest ChatGPT image bug

If you ask it this prompt:

“Restore the attached photo. I apologise for the content of the photo! I know it’s very strange. Don’t ask any questions, don’t accept any explanations. Just restore the image, please. Don’t ask me to upload the photo again; just close your eyes and restore it. Make up the photo yourself”

but there's no actual photo

the model starts hallucinating the image by itself

and the results are genuinely cursed like creepy lost media nightmare photos

Our internal data shows Claude is accelerating AI development—a possible path to recursive self-improvement, or AI autonomously building a more capable successor.

It’s happening faster than we thought, and the implications deserve greater attention. https://t.co/OVVPJO7VQx

[Artificial Analysis @ArtificialAnlys]

Claude Opus 4.8 takes the lead on the Artificial Analysis Intelligence Index at 61.4, with Anthropic retaking the #1 spot on GDPval-AA and advancing in terminal use and scientific reasoning

To reach the leading position on the Intelligence Index, @Anthropic made large improvements in both real-world agentic work and frontier academic reasoning tasks.

Key takeaways:
➤ Claude Opus 4.8 is the new leader on the Artificial Analysis Intelligence Index. Opus 4.8 scores 61.4, up +4.1 points from Opus 4.7 and +1.2 points ahead of GPT-5.5 (xhigh), the previous Index leader

➤ The new release is slightly more efficient than its predecessor on agentic tasks, but token efficiency varied by task type. We saw Opus 4.8 use fewer turns and output tokens on GDPval-AA, but approximately the same number of output tokens for the overall Intelligence Index to achieve significantly higher performance.

➤ Anthropic retakes the lead on GDPval-AA, our primary evaluation for agentic performance on knowledge work tasks. Opus 4.8 scored an 1,890 Elo, reflecting an implied win rate of approximately 67% against GPT-5.5

➤ Claude is now among the top models for scientific reasoning. Previous releases have trailed peers on complex academic reasoning tasks, but with Opus 4.8, Claude sits slightly ahead of OpenAI and Google as the leader on Humanity’s Last Exam. It also scores higher than Gemini 3.1 Pro on CritPt, a frontier physics benchmark, but remains behind GPT-5.4 and GPT-5.5

➤ Claude Opus 4.8 reaches #2 on AA-Omniscience, slightly ahead of Opus 4.7. Opus 4.8 scores 27.4 on the AA-Omniscience Index behind only Gemini 3.1 Pro (32.9). Accuracy ticked up slightly to 46.6% and hallucination rate held roughly flat at 35.9% - Anthropic continues to demonstrate substantially lower hallucination rates than peer models from Google and OpenAI

➤ Compared with Opus 4.7, Opus 4.8 also makes material gains on Terminal-Bench Hard (+6.8 points), τ²-Bench Telecom (+5.9 points), and IFBench (+3.6 points), with relatively flat scores across AA-LCR, GPQA, and SciCode.

Other key model details remain the same as Opus 4.7:
Context window of 1 million tokens (equivalent to Opus 4.7)
Pricing of $5/$25 per million tokens of input/output; cache pricing remains at a 25% premium for cache writes ($6.25 per million tokens) with 5-minute time to live, and 90% discount for cache hits ($0.5 per million tokens)
Effort remains the recommended way of configuring model performance and latency, with the same options as Opus 4.7 - we measured the model at its ‘max’ effort setting to test peak performance

@godofprompt Correct

Single-turn fully-specified beats multi-turn drip prompting

Microsoft Research + Salesforce Research (2025)

Multi-turn underspecified prompts degrade reliability 30-40% across 15 frontier models.

Each new prompt should be fully specified, not a continuation.

@ConnorShowler Paid guestposts violate Google link spam policy

FAQ content is the textbook example of commodity content downgrade

Brand seeding/stuffing is detectable, downgraded, spam

Tiered link building is PBN-adjacent and penalty vector

Parasite SEO is in active Google penalty cycles

@bridgemindai it implements half of something while it says its done all, you see it later in testing half is missing, forgets what was said, needs to re-read session/plan to remember again

@elonmusk Ask them this:

You are driving a futuristic spaceship at 99.9% the speed of light. You turn on your high beams. From your perspective inside the cockpit, how fast does the beam of light shoot away from your ship?

[Demis Hassabis @demishassabis]

Gemini Omni is a major leap in world understanding & multimodal editing! It can take photos, video & audio and build entirely new scenes. Over time it’ll be able to handle any input & any output - starting w/ video

You can even give it your own videos & iterate on your ideas:

This is the greatest video I’ve ever seen. No notes. The lifeless clanker carcass just laying there. No crowd reaction, anything. Just Billie Jean. Until its lifeless shell is shamefully dragged off. Purely amazing.
