AI Daily Digest — July 28, 2026
1. Nvidia deepens its frontier-lab bet with a reported $5 billion SSI partnership
Nvidia announced a long-term strategic partnership with Ilya Sutskever’s Safe Superintelligence, with broad reporting putting the investment around $5 billion. The deal gives SSI access to Vera Rubin systems and is expected to expand the lab’s available compute by roughly an order of magnitude over the next year, after a period in which SSI had relied mainly on Google TPU capacity.
Observation: The important shift here is not just the size of the check. Chip suppliers are tying themselves more directly to a small number of frontier labs and turning compute access into a strategic relationship.
2. Meta and BlackRock structure a $14 billion El Paso AI data center venture
Meta and BlackRock unveiled a joint venture for a 1-gigawatt AI data center campus in El Paso, with total development cost reported at about $14 billion. BlackRock-managed funds will own 80% of the project, Meta will keep 20%, and Meta will lease the capacity, with the site expected to come online in 2028.
Observation: Large AI infrastructure projects are increasingly being assembled like long-duration financial assets, with equity, debt, and leasing structures becoming as important as the technical build itself.
3. Nvidia turns the Hugging Face fallout into the Open Secure AI Alliance
Nvidia, Microsoft, IBM, Hugging Face, Palantir, Dell, CrowdStrike, the Linux Foundation, and other partners launched the Open Secure AI Alliance to develop open AI security tooling, agent harnesses, models, and defensive workflows. The alliance was explicitly framed against the backdrop of the recent OpenAI agent incident involving Hugging Face, where open systems were presented as more useful for auditing and forensics.
Observation: The security argument for open models is becoming more concrete. The debate is no longer only about ideology or ecosystem preference, but about which systems are easier to inspect, share, and defend in practice.

4. Moonshot AI releases the full weights for Kimi K3
Moonshot AI published the full weights for Kimi K3 on Hugging Face, describing a 2.8-trillion-parameter MoE model with about 104 billion active parameters, native multimodality, and a 1 million-token context window. The release also includes a technical report and parts of the supporting infrastructure stack, making it one of the most consequential open-weight model drops of the current cycle.
Observation: Direct weight access still matters. Releasing a model at this scale gives Moonshot a stronger path to developer adoption and keeps pressure on closed-model vendors across both cost and ecosystem reach.

5. Anthropic says Claude Mythos Preview found new cryptographic weaknesses
Anthropic reported that its unreleased Claude Mythos Preview, working over roughly 60 hours, identified an improved attack on the post-quantum signature candidate HAWK and a new technique that speeds reduced-round AES-128 attacks. Anthropic said the work does not affect production systems and that the findings were coordinated with NIST and the relevant researchers.
Observation: This is a useful marker for how frontier model capability is spilling into narrower technical research domains, where the value is less about chat performance and more about producing concrete, reviewable results.

6. Alphabet raises 2026 capex guidance to as much as $205 billion
After reporting strong Google Cloud growth, Alphabet raised its 2026 capital expenditure guidance to a range of $195 billion to $205 billion, up by as much as $15 billion from prior expectations. The company tied the increase directly to AI infrastructure demand that continues to outrun available supply.
Observation: The frontier AI race is still being governed by build speed and balance-sheet capacity. Model progress remains important, but the companies that can sustain infrastructure expansion are shaping the competitive ceiling.
