MIRA, A Preview Of The Endgame
Full-stack clinical replacement, closer every day.
We’ve seen AIME (and there’s an AIME article in this Nature, too), and now we have MIRA – an autonomous diagnostic and planning engine integrated into the electronic health record.
It’s agents writ large, with an orchestration layer and an interface for fetching and orchestration, and the beautiful figure they’ve included gives you a lovely overview of the principles upon which it operates:
As you’ve probably gathered, this is basically a “full stack” clinician replacement, a simulation in a sandbox environment in which LLM-powered agents interact with a simulated patient and clinically generated data for independent diagnosis and management.
It’s all very much in silico, as the patients for the LLM clinicians are also role-played by LLMs, and these agents obviously behave in complete and fashionable ways unlike the true chaotic nature of an emergency department encounter. There’s an entire exploration using the MIMIC-IV information as ground-truth, and, like most of these demonstrations, they don’t get published unless they’re demonstrating human-equivalent performance.
Regardless, it’s a sneak preview of the endgame – copilots that run under the surface of EHRs acting as oversight, “guardian angels”, and, ultimately, potential clinician replacement allowing less-skilled healthcare workers to operate above their usual scope.
