ox-alpha identification harness Tool
A working, dependency-light harness for identifying an anonymous model endpoint: an interactive multi-turn CLI plus a parallel probe runner that logs every raw request and response. Its tokenizer-differential technique - comparing reported prompt-token counts for the same string across models - identifies a model family without needing the model to cooperate, and it runs against any OpenAI-compatible API.
llm 0.35 Tool
Simon Willison's command-line tool and Python library for running prompts against many model providers from a terminal, with logging to SQLite; the 0.35 release adds support for the newly shipped gpt-6-astra model.
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.
TypeSafe Python SDK Tool
The public client library for TypeSafe’s typed System One decision API; Jev access itself remains early-access and waitlisted.
Prime Agent Tool
Open-source self-improving coding agent that gives the model a persistent Python session as its main tool - files, shell, sub-agents and context management all happen as code, and working state survives past a single chat window. MIT licensed; number one on GitHub Trending today.
FastMCP Tool
A Python toolkit that turns ordinary functions into Model Context Protocol tools, resources, and prompts with generated schemas, validation, and docs, and a client that handles transport negotiation, auth, and protocol lifecycle.
AlphaGenome API client Tool
Google DeepMind's open-source client for querying AlphaGenome variant-effect predictions from Python, for researchers who want programmatic access rather than the web portal.
