OpenScience is an open-source AI agent for scientific research. It reads papers, writes and runs code, works in notebooks and a terminal, and sends long jobs to Modal, your own servers, or a Slurm/PBS cluster. Give it a metric and Autoresearch runs experiments, logs every one, and keeps hill-climbing. Use 30+ models through one wallet, sign in with ChatGPT, or run a local model. It ranks #1 on agentic scientific research benchmarks. Free and open source.
