Is MLOps your edge?

Your best model from last month?
You probably can't reproduce it.

And when someone asks what changed… you don't have an answer.

One command. A complete record of what actually happened. Works with any training script — no code changes, no framework.

Let your agents roar.

works with PyTorch, JAX, TF — no wrappers, no decorators
The reality

Most ML teams can’t tell you what’s in their own model.

Not because they’re careless — loggers require constant manual work to maintain lineage. Lineage becomes ongoing technical debt. It’s never the highest priority. So in the end you’re guessing what’s changed.

01

Last month's best model. Nobody can reproduce it.

02

Two engineers changed the config. Neither remembers what.

03

A checkpoint in S3. No one knows what code produced it.

"We have datasets that I couldn't trace exactly how they were put together."

— ML Engineer, leading AI company
Sound familiar?

These aren't edge cases.
They're last quarter.

the ghost run

An H100 job finishes. Best result in weeks. The engineer who launched it had local changes that never got committed. The model is unreproducible. The $12,000 is gone.

s3 archaeology

48 hours tracking down which params.yaml produced the weights in s3://bucket/model_v2_FIXED_final/. Nobody knows. You try to reconstruct it from memory.

the jane departure

Your lead researcher accepted another offer. The only person who knows how the SOTA model was actually configured is walking out the door. That knowledge leaves with her.

None of these required an MLOps team to prevent. Just accurate lineage.

Lineage - How it works

One command.
No instrumentation.
Lineage captured at runtime.

No code changes. No frameworks. No loggers. No infrastructure lock-in.

Just roar run before your existing command.

A runtime observer records what actually happened — not what a logger remembered to log. If it ran, roar saw it.

  • env & deps
  • data & S3 objects
  • config & args
  • git SHA & diff
  • GPU / CUDA state
  • model artifacts
install
% uv tool install roar-cli
% roar init
# wrap any script — no code changes
% roar run python train.py
% roar run torchrun --nproc 8 train.py
Capture. Store. Control.

Capture what ran. Store the record. Control what runs next.

Three components give you a complete record of how your models are actually built — and what gets to run next. Use any piece on its own.

roar

If it ran, roar saw it.

A CLI that captures lineage at runtime — data, code, environment, artifacts. No code changes. No loggers. No frameworks.

GLaaS

Every model has a recipe.

A content-addressable registry of every artifact and job. Resolve any artifact's hash back to the code, data, and environment that made it.

TReqs

Approve before compute.

Training requests as pull requests. Nothing runs until someone — or a policy — says go.

Why TReqs →
What you get

Outcomes, not dashboards.

Questions you couldn't answer before, now answered on demand.

complete record

Every run captured automatically — a queryable record of what actually happened, not a convention or a log file.

run it again exactly

Re-run any past run with the same env, data, and config. Not "close enough."

what changed

Diff any two runs: code, data, hyperparams, hardware.

artifact trace

Every checkpoint points back to the exact run that produced it.

cost attribution

Know which experiment cost what. Know who spent what.

approve before compute

Nothing runs until someone — or a policy — says go. Runs are reviewed with context before they start.

TReqs

Decide what gets to run — and why — before the money moves.

Right now, anyone — or any agent — can burn $1,000 on a run. And you find out after.

TReqs turns that into a training request before it runs.

  • file a request: config + data + compute budget
  • team or policy reviews it before it starts
  • roar captures what actually ran
  • the request resolves with a real artifact
  • Without TReqs: runs happen. You investigate later.
  • With TReqs: runs are reviewed with context before they start.

Pull requests for training runs. Control plane for ML compute.
