Traceable Light

Verse 1

There's a child in a waiting room, years without a name,

A thousand doctor visits and the answers never came,

One in ten they told us, three hundred million strong,

Rare disease, but common pain — they've waited far too long.

Then February twenty-six, Nature hit the press,

A system born of agents learning how to reassess.

Chorus

DeepRare, DeepRare, shining traceable light,

Every reason on the table, every diagnosis right,

Multi-agent minds connecting what the doctors couldn't see,

Closing gaps in healthcare — oh, this changes you and me,

Traceable light, traceable light, finally burning bright.

Verse 2

Large language models woven into specialized tools,

Pulling up-to-date knowledge, rewriting all the rules,

Differential diagnosis, decision support in hand,

From the rarest of conditions to the corners of each land.

No more disparity depending where you're born,

A patient in a village gets the same care, same inform.

Chorus

DeepRare, DeepRare, shining traceable light,

Every reason on the table, every diagnosis right,

Multi-agent minds connecting what the doctors couldn't see,

Closing gaps in healthcare — oh, this changes you and me,

Traceable light, traceable light, finally burning bright.

Verse 3

Published there in Nature, DOI for all to read,

Ten-oh-nine-seven-nine, the proof inside the seed,

Agentic reasoning traced from symptom down to cause,

No black box, no mystery, just transparent, open doors.

Healthcare disparities were built on what we lacked,

Now the rarest get an answer — and we're never going back.

Bridge

We dreamed of machines that could listen and care,

That could search every journal, cross-reference, compare,

Now the agents are talking, and the knowledge is shared,

And the families who suffered know somebody's there —

Somebody's there.

Chorus

DeepRare, DeepRare, shining traceable light,

Every reason on the table, every diagnosis right,

Multi-agent minds connecting what the doctors couldn't see,

Closing gaps in healthcare — oh, this changes you and me,

Traceable light, traceable light, finally burning bright,

Traceable light — we're gonna be alright.
