KIMI K3 ON BASETEN - DAY 0 SUPPORT (SPONSOR) [4]

Kimi K3 is the strongest open-weights model yet. Baseten is serving
it from day 0.

🏆 #1 open model on Artificial Analysis

💻 #1 on Frontend Code Arena, ahead of every closed model

💸 Significantly more affordable than Fable 5

⚡ ~2x faster time-to-first-token on short prompts via custom kernels

Once model weights are released, Try Kimi K3 [5] on our Model APIs or
join our executive briefing [4] online tomorrow.

Baseten also has the fastest performance in the industry for GLM-5.2
on third-party benchmarks and real-world production usage.

NVIDIA IN TALKS WITH OPENAI TO GUARANTEE $250 BILLION FINANCING FOR
DATA CENTER (5 MINUTE READ) [7]

Nvidia is in talks to provide a roughly $250 billion backstop for
OpenAI as part of a massive data-center project. The guarantee will
help OpenAI lease a 10-gigawatt project that Softbank's energy
subsidiary is developing. Nvidia's backing allows the data center
developer to raise debt at more favorable terms. Under the deal,
Nvidia would guarantee a series of financing vehicles intended to make
lenders feel more confident that funding behind the project is secure.


META GIVES FACEBOOK MARKETPLACE ITS OWN APP CALLED SELLER (6 MINUTE
READ) [8]

Seller is an early experimental app from Meta that aims to be to
sellers what tools to edit videos were to content creators. It is free
and will also be available in web browsers. The app has AI features
that make selling items less of a hassle. Users can sign into Seller
with their Facebook accounts, and listings are automatically synced.

SPACEX EYES TOWER CATCH FOR NEXT STARSHIP AFTER AUSPICIOUS END TO
13TH FLIGHT (11 MINUTE READ) [9]

SpaceX's 13th Starship test flight ended in an intact splashdown in a
remote section of the Indian Ocean on Friday. The vehicle appeared to
be in fine shape on landing. SpaceX will attempt to catch the ship
with its launch tower on the next test flight. The next steps for
Starship are getting to orbit and returning the ship to the launch
site, which will give SpaceX the capability to begin launching
operational Starlink V3 satellites.

TEAM USES ALPHAFOLD AI TO REDESIGN GENE-EDITING PROTEINS TO MAKE THEM
SAFER (6 MINUTE READ) [10]

A team based in China modified AlphaFold to help identify what parts
of a gene-editing protein enable mistakes. They then modified these
areas to reduce problematic off-target effects. Producing gene-editing
systems tailored to prevent known off-target events is useful for
fine-tuning protein-DNA interactions, which could have applications
beyond gene editing.

ISOCHRONES API (1 MINUTE READ) [12]

The Isochrones API calculates the area that a person can reach from a
specific origin point within a set amount of time. An isochrone
accounts for actual road network travel times to create a polygon that represents true reachability. The API can be useful for delivery
logistics, finding properties within a set distance from a landmark,
and urban planning.

THE NEW RULES OF CONTEXT ENGINEERING FOR CLAUDE 5 GENERATION MODELS
(5 MINUTE READ) [13]

Anthropic removed over 80% of Claude Code's system from its more
advanced models. This post discusses how to apply the lessons its team
learned from context engineering in Claude Code. The prompt is only a
small part of the context Claude gets. The rest of the context is
assembled from Skills, CLAUDE.md files, memory, and other sources.
Context engineering has a big impact on the results generated when
using Claude Code.

AI IS OIL, NOT GOD (5 MINUTE READ) [14]

AI is more of an economically useful commodity than a supremely
intelligent being that will make humanity subservient. Several leaders
in the AI industry have recently come out in support of open-weight
models. If these leaders believed that AI was going to become
conscious and take over the world, they likely wouldn't be as openly pro-diffusion.

SILICON VALLEY SPLITS OVER CLOSING THE BORDERS TO CHINESE AI (11
MINUTE READ) [15]

Companies like Anthropic and OpenAI claim some AI models are too
dangerous to be developed in the open and must be tightly controlled
for safety. The rest of the industry says that open source AI models
must remain open for people to further develop technologies and build
new businesses. China's rapid progress in open source AI models is
escalating the fight. US officials are still debating whether to
approach regulating Chinese open source models as a national security
issue or issue a kind of blanket ban.
