Anthropic Engineer Andrej Karpathy:

"The biggest mistake in AI right now - people are forcing agents to work instead of mastering the model first

We made that mistake in 2016 at OpenAI - It cost us 5 years "

what Karpathy actually means:

step 1 → stop forcing your agent to do everything, understand the model underneath first

step 2 → demos are easy - products take a decade. self-driving proved it - if you skip the foundation, everything breaks

step 3 → the agent is not the product. the foundation is. build that - and agents emerge on their own

"you building agents right now - you're at the forefront. not OpenAI. not DeepMind. you "

[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.

Ahora voy a presentar los algoritmos que hacen vulnerable el software de los hermanos Bautista y que permiten que estados poderosos con capacidad computacional puedan reemplazar a colombianas y colombianos

Cómo no se dejó auditar el software no se descubrió está terrible vulnerabilidad y se prefirió una derrota posible derroya pírrica del progresismo a cambio de la soberania nacional. Píeeica porque elmprogresismo es ahora más grande que cuando el pueblo me eligió lo cual demuestra mucha gratitud y reconocimiento del pueblo de Colombia que no nos ha quitado poder de la palabra sino más poder.

Ahora invito formalmente al presidente Donald Trump, a hablar porque a la situación creada en Perú, Colombia y Venezuela creo que hay que meterle mucha sabiduría antes de propiciar una inestabilidad que tendría mucha sangre humana y un empoderamiento del narcotráfico como nunca.

Aquí para la https://t.co/s2IoNfi9bx Colombia dejo los algoritmos existente que permiten la vulnerabilidad externa del software.

Ya se sabe que los algoritmos que suspendieron de la metabase del E14 como
La estampilla de la historia y el candado Hash si permitieron cambiar formularios E14 ya puestos.

Ya sabemos que algunos jurados del exterior que no podían ser jurados residentes en Colombia sin anular lo hecho en las urnas eran residentes de Colombia

Ya sabemos que entraron millones de dólares del exterior invertidos en desprestigiar al gobierno, a mí al Pacto histórico y a Iván Cepeda, que le hicieron creer a millones de colombranos que Iván era guerrillero cuando nunca cogió un arma, y solo investigo el asesinato del su padre senador hasta saber el autor oficial y funcionario público y eso lo llevo como a mi, por ser parresiastas a averiguar los culpables del genocidio del pueblo humilde de Colombia.

Aquí pueden leer un poco difícil y para que quede en al historia de estos días, y aprenda el pueblo a unirse y defender sus intereces, los algoritmos vulnerables del software privado de los hermanos Bautista

🚨 CYBER INTELLIGENCE ALERT / DIAGNOSTIC REPORT: EVOLUTIONARY ANALYSIS OF NETWORK INFRASTRUCTURE — COLOMBIA CASE 🇨🇴

[STATUS: PASSIVE FORENSIC ANALYSIS / PROCESS IN DEVELOPMENT / HISTORICAL MITIGATION VERIFIED]

PERIMETER EXTERNAL THREAT ASSESSMENT AND HISTORICAL MONITORING OF SIMILAR DOMAINS

Data analysis reveals the existence of a latent ecosystem of domains with typosquatting and test subdomains. However, expert data cross-referencing confirms that these environments correspond to processes in development or previously mitigated infrastructures, ruling out the presence of active intrusive indicators or ongoing phishing campaigns on these specific vectors.

🏢 Reference Entity: External infrastructure and name resolution configurations associated with the National Civil Registry.

🔍 Threat Status: ENTIRELY AT THE SUSPECTED LEVEL / NON-INTRUSIVE PROCESS. The findings confirm the absence of active compromise of internal systems. The analyzed domains are inactive, suspended, or correspond to legitimate external platforms with no malicious connection.

🌐 1. FORENSIC INFRASTRUCTURE ANALYSIS (CERTIFICATE HISTORY)

Monitoring the issuance of TLS security certificates and transparency logs reveals a historical pattern of registrations dating back to 2023, showing the evolution of domains with name variations:

Identity Validation Ecosystem (Historical Requests):

cedula-registraduria-gov. com / *.cedula-registraduria-gov.com (First observed: August 26, 2025).

cedula-registraduria-gov. net / cedula-registraduria-gov. org (First observed: September 4, 2025).

eleccionescolombia-registraduria-gov. co (First observed: February 24, 2026).

sregistraduria-gov-co.sitelop. com (First observed: March 28, 2026).

Nature of the Environments: The presence of wildcards (*) and specific subdomains geared toward targeted queries (such as "cédula" [ID card] or "elecciones" [elections]) is typical of external logical testing structures or perimeter replication setups under development that require extended implementation timeframes; this does not, in itself, constitute an Indicator of Compromise (IoC) or an intrusion into the state network.

📊 2. VERIFICATION OF SUSPENSIONS AND HISTORICAL MITIGATION

Technical forensic analysis of HTTP header responses allows for the dismissal of immediate phishing risk vectors raised in previous reports:

A. Status of the domain registraduria-gov .com
Forensic Diagnosis: The domain previously identified as a potential critical vector is completely disabled and inactive.

Technical Evidence: A query of the Nginx web server response (running on Ubuntu OS), dated January 12, 2026, at 16:30:19 GMT, returns a status displaying the string "Contact Verification Suspension Page" (hosted on IP infrastructure 54.38.220.85 in Roubaix, France). Conclusion: It has been technically verified that the website does not operate as an active phishing campaign, having been permanently taken down and suspended by domain registrars in early 2026.

B. Nature of the domain kamtridit .cz
Forensic Diagnosis: The portal is ruled out as malicious within the analysis environment.

Technical Evidence: The HTTP/2 header with status 200 OK, captured on June 2, 2026, at 03:17:50 GMT, identifies the domain as hosted on Vercel and Amazon servers (IP 216.150.16.129 in California, USA). The site legitimately presents itself as "Kam třídit – mapa pro správné třídění odpadu" (a Czech public service portal dedicated to waste sorting and recycling mapping).

Conclusion: The domain belongs to a legitimate foreign public-service platform with no connection to social engineering activities or fraud targeting Colombian national sovereignty.

🛡️ TECHNICAL INTELLIGENCE CONCLUSION

The analyzed data demonstrate that warnings regarding alleged externally exploited vulnerabilities lack an active or functional attack vector as of today. While the existence of similar domains necessitates constant brand and reputation monitoring, historically implemented mitigations (such as the forced suspension of registraduria-gov. com in January 2026) and the legitimate nature of the supporting infrastructure reduce the operational risk profile to controlled levels, ensuring the external perimeter stability of the digital gateways.

[Ethlabs @ethlabs_org]

Announcing Ethlabs: a non-profit R&D lab for Ethereum and ETH

Our mission is to make Ethereum the settlement layer of the global economy.

The internet became global because shared protocols created a common language between networks. Private systems remained useful, but bounded. Finance is approaching a similar moment. As value, assets, and markets become digital, the world needs shared settlement infrastructure.

Ethereum is uniquely positioned to become that shared base layer, the neutral foundation on which users, institutions, and agents can transact without intermediation.

What we believe:

• We believe credible neutrality matters. Ten years of uptime and the lowest counterparty risk. Ground that cannot be pulled away by any one country, institution, company, or person.

• We believe ETH matters. The most valuable, programmable store of value. A decade of broad distribution, deep liquidity in onchain markets, and maximally trustless asset on Ethereum.

• We believe DeFi matters. Markets, liquidity, credit, exchange, and coordination, open to anyone.

• We believe adoption matters. Principles do not change the world until people benefit from them.

We sit between two worlds: real usage from the builders at the frontier, and the protocol that has to support it. We work with users, applications, wallets, L2s, infrastructure teams, institutions, ETH holders, core devs and researchers, then turn what they actually need into protocol work, shared standards, infrastructure, and shipped products.

Ethlabs is independent but Ethereum is a shared project. We are one node in a much larger network of stewards. This is the multi-node future.

We have spent the better part of the past decade contributing to Ethereum core research and development.

We are opinionated and transparent. We move with urgency, learn in public, and course-correct when we’re wrong.

We are building a lean, talent-dense team for people who want to do the most important work of their careers: [email protected]

[vitalik.eth @VitalikButerin]

Looks like the options thing is happening already!

See also: various people thinking through and building different versions of the idea in the thread: https://t.co/gFNEvCbHct

Though I do strongly urge that if any of these get on mainnet quickly, we formally verify it first. I hope @vyperlang and/or https://t.co/OMFlWRqJda folks ( @Fricoben) can help!

(Also, now is a good time to be thinking about robustness-optimized oracles)

[Ethereum Daily @ETH_Daily]

🔥 Vitalik recently shared a new idea for building stablecoins on Ethereum.

Instead of the current way — where you deposit ETH, borrow dollars against it, and risk getting liquidated if the price drops — he suggests splitting the ETH into two tokens. One token works like a stable dollar with much lower risk of big losses. The other token takes the upside when ETH goes up. These two tokens always add up to the original ETH, so there’s no debt and no forced liquidation when prices fall.

This approach could become a new trend in DeFi. It trades a small amount of price drift for a much safer and simpler system that doesn’t rely on constant price monitoring or sudden liquidations.

Ethereum has always moved forward because of people and teams willing to try new ideas early. We need more projects experimenting with concepts like this to help the ecosystem grow stronger.
