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?
Good Morning from San Francisco, Microsoft and OpenAI just signed a truce. After months of heated negotiations that nearly triggered

PTH files are PyTorch's native format for saving model weights, architecture definitions, and training states using Python's serialization protocol.
PTH files use Python's pickle module to serialize PyTorch tensors and model state dictionaries. They can store complete models or just the learned parameters.
The format supports both eager and scripted PyTorch models, preserving computational graphs when needed.
As PyTorch's standard format, PTH files are ubiquitous in research and production. They enable easy model sharing within the PyTorch ecosystem and support flexible saving strategies.
Most academic papers using PyTorch distribute their models as PTH files.
