Gemini 4 Carbon arrives

The Signal · 2026-10-29

Two weeks after Argon, Google DeepMind has another frontier model. It's called Gemini 4 Carbon, and the headline claims are cybersecurity and agentic coding. Access is locked down: most builders can't touch it yet. The frontier release cadence is back.

Also today: Google launched a developer platform letting businesses plug their services into Gemini and Search, putting Google between users and third-party apps.

Alphabet shares fell 7% after hours on an earnings miss. AI spending passed 50 billion dollars in the third quarter.

That's today's Signal. Thanks for watching.
