phrugsa-limbunlom/deltaflow
Optimal-transport flow matching built around the displacement between two distributions.
Works.Tested on 2026-10-28. From the README alone, on Linux with Haiku.
What we checked
Does it run from the README?Yes. Running in 7:43 on a clean Linux box.The run
Tested Oct 28, 2026, rev fdf4ba9.
Does it do what the README says?5 of 5 claims held up.Evidence
“Every probability path returns the interpolated state x_t and its conditional target velocity u_t (interpolant example prints x_t and u_t and passes boundary checks)”
Expected x_t and u_t printed for each t, boundary conditions OK. Got Boundary conditions OK..
“The examples tree is a runnable curriculum (linear interpolant example runs)”
Expected t=1.00 row printed with x_t endpoint equal to x1. Got t=1.00 x_t[0]=[1.5409960746765137, -0.293428897857666].
“Flow matching regresses a velocity field onto the conditional velocity of the path (training example runs and reports loss)”
Expected final loss printed. Got final loss: 4.1941.
“A learned field is integrated with a simple Euler or Heun solver to produce samples”
Expected sample mean and std printed. Got sample mean: [0.019584309309720993, 0.05306430160999298].
“Posterior sampling for an inverse problem reuses the pretrained field and reports observed-region MSE”
Expected observed-region MSE printed for independent-coupled model. Got observed-region MSE, independent-coupled model: 0.0633.
Which setups did we try?Works with Haiku. Unverified with Luna.Setups
Linux / Haiku: works, Oct 28, rev fdf4ba9. Linux / Luna: unverified, Oct 28, rev fdf4ba9.

Is it safe to run?No unexpected network or file activity found in these checksWhat we saw
No problems traced to this repository code in these checks; a short run cannot prove safety. 76 listed items (named-host connections, static matches, dependency advisories) are below and do not change this verdict.
OSV reports a known vulnerability in this dependency version. 3 distinct locations. 38 findings.
Reviewed as expected for a test run: attempted writes that failed, so nothing was written.
Full event, path and process lists for each observed setup:
A quiet run is not a safety guarantee.
