MODULATE RAISES $25M TO BUILD THE AUDIO INTELLIGENCE LAYER FOR VOICE
AI (SPONSOR) [4]

Modulate raised $25M, led by Future Ventures [5], to build the
understanding layer for voice AI.

Transcripts drop the fraud, frustration, and abuse hiding in
conversations. Velma, Modulate's audio-native model, catches them by orchestrating 100+ voice-specialized submodels running on raw audio.

¨ Stop fraud catch deepfakes with the #1-ranked detection model
on Hugging Face
¨ Catch AI agent failures flag hallucinations and compliance
violations in real time
¨ Keep customers spot churn and dissatisfaction signals
¨ Protect human and AI agents flag risk and abuse
¨ Build your foundation with itself-serve APIs; top ranked
Hugging Face Leaderboard STT API

The funding brings more models, deployment options, and broadens the
APIs for teams building with voice.

GOOGLE ANNOUNCES GEMINI 4 ARGON AI MODEL, BUT YOU CAN'T USE IT YET (3
MINUTE READ) [7]

Google's Gemini 4 Argon model offers industry-leading performance in
coding, knowledge work, and cybersecurity. Google's engineers are
already using the model extensively, and Argon-powered agents have
been working to migrate C/C++ codebases to Rust across Google. The
model supports an output limit of 1 million tokens. It will be priced
at $2 per million input tokens and $10 per million output tokens for a
limited time. The model is still in limited testing, and there is no
timeline for when it will be available to enterprise and consumer
customers.

GOOGLE FIGURES OUT HOW TO WATERMARK AI-DESIGNED PROTEINS (11 MINUTE
READ) [9]

The DeepMind team at Google has developed a technique that can create watermarks on protein sequences without compromising the protein's
function. The watermark is impossible to remove and can survive basic exporting, resizing, and other editing. The system could be used to
give DNA synthesizers greater confidence in their sources.

MOST POWERFUL OBESITY DRUG YET: PEOPLE LOST UP TO 25% OF WEIGHT IN
TRIAL (5 MINUTE READ) [10]

Late-stage clinical trial data on the obesity drug retatrutide showed
an average loss of 25% of body weight after 90 weeks. More than a
third of the participants taking the drug in the trial lost 30% or
more of their weight. The drug also helped reduce knee pain and sleep
apnea events, and it improved cardiometabolic measurements across the
board. At the start of the trial, more than a third of trial
participants had prediabetes - the condition had resolved in more than
90% of those participants by the end.

COMMIT DESCRIPTION AS A THINKING TOOL (3 MINUTE READ) [12]

Writing a commit description can help you reflect on the changes that
AI made. It also serves as a way to check if everything is as
intended. Being able to explain why you are shipping something will
help you explain or fix it if it breaks later. AI can do the work -
writing why is where you find out whether you understand what you are
shipping.

TECH CEOS PRIVATELY QUESTIONED AMODEI FOR SOUNDING AI ALARM BELLS (7
MINUTE READ) [14]

AI chief executives gathered with Trump at the White House on Tuesday
to discuss a statement of principles to keep AI models safe. Behind
the scenes, the executives questioned Anthropic CEO Dario Amodei about
his warnings about the dangers of AI, asking why he was being so
extreme in public about the capabilities of AI models and the risks
they pose. Amodei told them it was important to be honest with the
public about model capabilities and not play down risks. He believes
that safety is possible if the industry and administration work
together.

THE ROUTER ECONOMY (18 MINUTE READ) [15]

AI assistants are becoming a router between people and every
business. They decide who gets the work, which moves where money can
be made. The router absorbs capability and decision-making. The margin
goes to whoever holds what the router cannot take and whoever signs
for what the router cannot sign.
