torchwright builds working transformer weights from Python - no training involved News
A project called torchwright constructs concrete weights for a standard transformer architecture directly from a typed computation graph written in Python, producing models that load through ordinary Hugging Face APIs with no gradient training at any point.
Anthropic launches Claude Science, an AI workbench that keeps data in the lab and checks its own citations News
Anthropic released Claude Science, a beta workbench that wires Claude into researchers' real tools -- PubMed, Jupyter, HPC clusters -- runs on the lab's own hardware so sensitive data never leaves, and pairs a working agent with a separate reviewer agent that flags and corrects citation and calculation errors.
chessformer_lens Tool
A pip-installable mechanistic interpretability lens for square-token chess transformers. It visualizes the move policy live and lets you ablate any attention head with a click, on top of the Maia-3 model family.
AskChem Tool
A live chemistry search system that retrieves individual claims rather than papers - 2.4 million typed claims from 147,000 papers, each carrying a source identifier and a verbatim quote. Free web interface plus REST, SDK and MCP access so agents can query the same claim store.
