🤖 Anthropic unveils Claude Fable 5 LINK

Anthropic has released Claude Fable 5, a public version of its Mythos model that the company previously held back over safety concerns, now fitted with built-in safeguards to stop deliberate misuse and security breaches.

Unlike Mythos, which stays limited to select organisations, Fable 5 goes to enterprise customers and paid subscribers, with barriers that block responses on cybersecurity, chemistry and biology while still handling software engineering and scientific research.

Anthropic admits some safeguards are "stricter than would be ideal" because benign requests may get flagged as risky, and it also announced Claude Mythos 5, a similar model with the cyber safeguards lifted.

🚀 SpaceX IPO hits 4x oversubscription LINK

SpaceX's record initial public offering has drawn nearly four times the demand it set out to raise, pulling in over $250 billion in orders against the $75 billion target at a $1.8 trillion valuation.

Pricing is expected Thursday with shares set at $135, and analysts say long-only funds have placed sizable orders, though demand could still shift since large institutional investors often submit their orders late.

Some analysts call the market drop a "pre-mega-IPO liquidity squeeze," blaming the SpaceX deal for tech stocks tumbling and crypto markets losing more than $180 billion in a week as investors sell to fund their orders.

🔋 GM joins race to build batteries for AI data centers LINK

GM is entering the energy-storage market for AI data centers and industrial sites, developing a new sodium-ion battery chemistry through a partnership with startup Peak Energy that will integrate the cells into its grid-scale products.

No automaker outside China has announced plans to build sodium-ion cells, which swap out key materials to make batteries cheaper and less prone to overheating, though they must be larger and heavier to store the same electricity.

GM's first sodium-ion cells enter trial production at its Battery Cell Development Center in 2028, and meanwhile the automaker will sell lithium iron phosphate cells to LG Energy Solution for use in energy-storage systems.

🏗️ OpenAI wants its biggest data center yet, paid for by Nvidia LINK

OpenAI is in talks to lease a planned 10-gigawatt data center in Ohio, built on federal land in Pike County by SB Energy, the developer majority-owned by SoftBank, according to The Information.

The full buildout would cost at least $500 billion, with OpenAI signing a 20-year lease, its largest infrastructure commitment yet, while Nvidia would serve as guarantor for both the lease and the project financing.

The first phase, at 800 megawatts, is expected by 2028, on a site that previously housed a uranium enrichment facility, though negotiations are still ongoing and the plans could change.

💬 EU orders Meta to restore rival AI chatbots on WhatsApp LINK

The European Commission has ordered Meta to restore free access to rival general purpose AI assistants on WhatsApp, an interim measure while the EU's executive body finishes its antitrust investigation into the platform owner.

Meta started blocking third party AI assistants in WhatsApp in October 2025, prompting the EC to open its investigation in December over concerns the policy could stop rival AI providers from offering services on the platform.

The EC says Meta abuses its dominant position in chat apps by favoring its own Meta AI chatbot, and Meta has five working days to comply, though a spokesperson called it "regulatory overreach" and said the company will appeal.
