WORKOS LAUNCHES AUTH.MD - AN OPEN PROTOCOL FOR AGENT REGISTRATION.
(SPONSOR) [4]
Sign-up forms were built for humans in browsers, so how do AI agents programmatically register with services?
Enter auth.md. By exposing a single, machine-readable Markdown file at
your service root, AI agents can dynamically discover your OAuth
Protected Resource Metadata, parse required scopes, and authenticate seamlessly.
With native support in WorkOS AuthKit, you can now implement this
protocol out of the box, giving AI tools a standardized, secure way to
log into your application.

INITIAL IMPRESSIONS OF CLAUDE FABLE 5 (12 MINUTE READ) [6]
Anthropic claims that Claude Fable 5 offers the same performance as
Mythos 5 but with stricter guardrails. It has a 1 million token
context window with 128,000 maximum output tokens. The model is priced
at twice the price of the Claude Opus models at $10 per million input
tokens and $50 per million output tokens. The Claude API has new
mechanisms for alerting users when these guardrails are activated, and
there is an option to request to fall back to another model
automatically if something gets rejected.
ELON MUSK'S FIRST-GEN ORBITAL DATA CENTER CRAFT SPANS WIDER THAN A
BOEING 747 AND RUNS AN INTERCHANGEABLE CHIP PAYLOAD (2 MINUTE READ)
[7]
SpaceX's AI1 satellite will have a 70-meter deployed wingspan and
carry a 150 kW peak compute payload. It will have an interchangeable
hardware design that will let different chipmakers supply the
processors. The craft will operate at roughly 600 km. SpaceX has
already filed with the FCC to launch up to a million orbital data
center satellites.

SCIENCE & FUTURISTIC TECHNOLOGY
NASA'S NEXT MOON MISSION IS A RUBE GOLDBERG MACHINE OF CORPORATE
FAILURE POINTS (3 MINUTE READ) [8]
NASA has announced the crew for its upcoming Artemis 3 mission. The
mission will require the astronauts to travel to Earth's orbit inside
NASA's Orion capsule, where they'll meet and board both Blue Origin's
Blue Moon lander and SpaceX's Starship in quick succession over three
days. It is designed to lay the groundwork for the crewed Moon landing tentatively scheduled for 2028. NASA is confident that Blue Origin's
New Glenn will be ready for the mission despite the recent explosion
that dealt significant damage to the company's launch pad.
WORLD'S FIRST WIND-POWERED UNDERWATER DATACENTRE STARTS OPERATING IN
CHINA (4 MINUTE READ) [9]
The Shanghai Lingang undersea datacenter demonstration project is a
joint effort between HiCloud Technology and China Communications
Construction, a state-owned company. The datacenter, which has a
capacity of 24 megawatts, is submerged 10 meters below the surface of
the water. It is powered by a nearby offshore windfarm. The datacenter
uses less energy compared to land-based datacenters because of the
natural cooling effect that comes from being submerged in seawater.

AHACREATOR IS REINVENTING INFLUENCER MARKETING WITH AI (SPONSOR) [10]
Influencer marketing has hit a structural bottleneck. The reason? Too
much of it still runs on emails, spreadsheets, and manual follow-ups. AhaCreator 3.0 [10] is the AI solution you've been waiting for:
multimodal matching, instant content review, 100,000+ onboarded
creators. Scale your influencer program from one-off to 500+ monthly

CONTAINER (GITHUB REPO) [11]
container is a tool for creating and running lightweight virtual
Linux containers on Mac. It consumes and produces OCI-compatible
container images and can pull and run images from any standard
container registry. The tool uses the Containerization Swift package
for low-level container, image, and process management.
KTX (GITHUB REPO) [12]
ktx is an executable context layer for data and analytics agents. It
allows AI agents to query data accurately and with full context. ktx
is self-improving and can teach agents how to query data warehouses
accurately. It learns from company knowledge, maps the data stack,
builds a semantic layer, and serves agents at execution. A video
explaining the tool is available in the repository.

WHAT IT FEELS LIKE TO WORK WITH MYTHOS (11 MINUTE READ) [13]
Anthropic's Mythos-class AI model, Fable, represents a very real leap
over past models. In informal experiments, it outperforms every other
public model by a considerable margin. The model has guardrails that
prevent it from being used for things like cybersecurity, but it can
still produce impressive results from single prompts. This post looks
at several examples of outputs from the model and describes what it is
like working with it.
APPLE WINS CONSUMER AI BY DEFAULT (14 MINUTE READ) [14]
Apple is set to win AI from a consumer perspective. The company may
seem late to the AI race, but it was just doing what it has always
done: watch new products and services develop and then jump in later
with a better user experience. Its latest product announcements may
seem underwhelming to the people living at the edge of AI, but most
people don't need or even want that. Apple is set to bring AI usage
mainstream with Apple Intelligence and the new Siri AI - if it is able
to roll out what it showcased at WWDC.
