Anthropic launched Claude Opus 5 on July 24, 2026: a model that approaches Fable 5’s performance while costing half as much per task. We cover the benchmarks, real use cases, and how to start testing it today.

The NSF allocated $83 million to a data backbone for AI-powered science, a quieter but technically concrete announcement next to the Genesis Mission’s $5 billion. The investment aims to give unified access to scientific datasets for training and validating models reproducibly.

A historian at the University of California, Santa Cruz used Claude Code to build the Book Prize Index, a free database of 6,500 nonfiction books that won or were finalists for major English-language prizes. The tool uses semantic search to replicate the experience of browsing a well-curated library shelf, as a direct response to the flood of generic AI-generated content.

Gigatoken is a Rust tokenizer that reaches 24.53 GB/s in benchmarks, up to 989 times faster than HuggingFace Tokenizers. It supports more than 15 model families, from Llama to DeepSeek, and installs with a simple pip install.

A public ChatGPT thread exploring a possible counterexample to the Jacobian conjecture put one of algebra’s longest-standing open problems back in the spotlight. We cover what the conjecture states, what’s actually been proven, and how to verify it yourself with Python.
