Which Claude model should you build with?
Our new guide breaks down when to use Fable 5.2, Opus 5.5, Sonnet or Haiku. It also covers when to adjust effort instead of switching models, and how to save cost by putting subagents on smaller models.

During pre-release testing, Claude Fable 5.2 and Claude Mythos 5.2 worked on ambitious projects in many different fields. Here are a few.
From a one-paragraph prompt, Fable 5.2 designed three working electronic devices, including this home voice assistant hub.

Phantom users paid almost $5 MILLION in wallet fees last month 🤯
That’s from swaps & bridging in October.
→ Phantom: 0.85% on most swaps
→ Jupiter Wallet: 0% additional platform fee
On a $1,000 swap, Phantom’s fee alone is $8.50.
Those fees add up the more you trade.
So for your next swap - Just Use Jupiter 🪐

The AI layoff gamble is backfiring.
Companies that rushed to replace workers with AI are now cleaning up the mess, per The Guardian.
Meta scaled back plans to cut staff and use more AI agents after employees spent growing time cleaning up the agents’ technical and security errors. It’s now rehiring managers.
Microsoft and McKinsey are limiting employee AI use as costs pile up.
Walmart workers say AI scheduling and task tools set impossible standards and generate false alerts.
The payoff isn’t showing up: 90% of executives say AI hasn’t yet boosted productivity at their companies, per an Atlanta Fed working paper.
Yet more than 112,000 US job cuts this year have cited AI, per Challenger, Gray & Christmas.

🇵🇾 Chaos on the streets as Paraguay’s largest digital bank collapses
Nearly 3 million customers affected as the country faces a major political and financial crisis.
Paraguay’s Central Bank (BCP) seized Ueno Bank, the country's largest digital lender, after its solvency ratio collapsed to less than half the legal limit.
Central Bank President Carlos Carvallo resigned at the request of President Santiago Peña. Carvallo previously chaired the finance company that evolved into Ueno Bank, drawing heavy criticism over regulatory blind spots and conflicts of interest.
The Specialized Unit for Economic Crimes and Anti-Corruption ordered the detention of eight high-level executives and figures tied to the bank, including founder and majority shareholder Miguel Vázquez and Ueno Bank President Juan Manuel Gustale.
The intervention completely froze Ueno Bank’s digital app, credit cards, and transfer capabilities. This has locked out roughly 3 million users, an estimated 60% of Paraguay's adult population, leaving many with no immediate way to access their money.
The state health and pension fund (IPS) has an estimated $380 million in public retirement funds invested in Ueno Bank.
Angry citizens, savers, and pensioners flooded the streets of the capital and gathered outside closed branches, demanding their cash and chanting for political accountability.

BREAKING: A mystery seller is trying to dump about $500 million in data center loans all at once, per Bloomberg, days after the midterms raised doubts about many projects.
The anonymous seller is auctioning a dozen loans, including a $25 million piece of financing for a huge Stargate site in New Mexico, the joint project of OpenAI, SoftBank and Oracle.
Oracle has already sent that site’s developer a force majeure notice, a legal claim that events beyond its control may excuse it from its obligations.

On today's stock market crash:
As an investor, on days like today, you have to ask yourself one question: What fundamentally changed over the last 24 hours?
The shift in the fundamental backdrop cannot be attributed solely to the Midterm Election results; markets had already largely priced in the outcome.
So, what changed between yesterday and today? What is the fundamental reason for today's decline?
One of the most likely catalysts is growing concern about a potential "ban" on AI, or at the very least, severe regulation of the industry.
Over the last 24 hours, Democratic lawmakers have publicly called for restrictions on advanced AI development, including an outright "ban on artificial superintelligence."
Frankly, an outright ban will not happen.
Such a ban, if even possible to enforce, would effectively mean the US surrendering its position in the global AI race to China.
Does this mean AI is "over" or today's stock market crash marks "the end?" Absolutely not.
Rather, we believe we are witnessing a sudden shift in sentiment colliding with excessive levels of leverage, potentially triggering forced liquidations by several major institutional investors.
Therefore, today's downturn is more technical than fundamental. This is not to discount the concerns around regulation, they are legitimate. But price action right now does not look orderly or rational.
We are in the midst of the biggest technological revolution in human history.
Zoom out and remain calm.
