What if we set GPT-4 free in Minecraft? ⛏️ I’m excited to announce Voyager, the first lifelong learning agent that plays Minecraft purely in-context. Voyager continuously improves itself by writing, refining, committing, and retrieving *code* from a skill library. GPT-4 unlocks a new paradigm: “training” is code execution rather than gradient descent. “Trained model” is a codebase of skills that Voyager iteratively composes, rather than matrices of floats. We are pushing no-gradient architecture to its limit. Voyager rapidly becomes a seasoned explorer. In Minecraft, it obtains 3.3× more unique items, travels 2.3× longer distances, and unlocks key tech tree milestones up to 15.3× faster than prior methods. We open-source everything. Let generalist agents emerge in Minecraft! Welcome you all to try today: voyager.minedojo.org Paper: arxiv.org/abs/2305.16291 Code: github.com/MineDojo/Voyag… Deep dive with me: 🧵

At #EHR in-box conf., Maria Byron describes @UCSFHospitals experience creating option to turn electronic queries that take >5 min into billable “Medical Advice Message.” Generally ok w/ patients & popular with clinicians. Small co-pay for some pts. Overall positive intervention.



oh woah, first full EHI export capability in the wild (afaik). Epic obviously * Tsv format * Not FHIR or another standard On the plus side, for those who've never used Epic, you can finally understand their underlying data model open.epic.com/EHITables
