A 23-year-old ex-OpenAI researcher just raised $1.5B predicting AGI by 2027—with zero investment experience. History shows fever dreams burn billions while real breakthroughs start small. Are we watching the next Amazon or the next Theranos?
Albania just appointed the world's first AI government minister to handle all public procurement. Diella promises corruption-free contracts as the country races toward EU membership by 2027. But can algorithms resist human manipulation?

PB (Protocol Buffer) files are TensorFlow's binary format for storing trained models, using Google's efficient serialization protocol for structured data.
Protocol Buffers serialize TensorFlow graphs and weights into a compact binary format. The .pb extension typically indicates a frozen graph with both architecture and weights.
The format is language-agnostic and platform-independent, making models portable across different systems.
PB files enable efficient model deployment in production environments. They're optimized for size and loading speed, crucial for serving models at scale.
TensorFlow Serving and TensorFlow Lite rely heavily on this format for model distribution.
