Tool — Experiment Tracking

Every training run,
comparable to the last.

Weights & Biases tracks every training and fine-tuning run — hyperparameters, metrics, and outputs — so the question "was run three actually better than run one" has a real answer instead of a guess from memory.

What it is

Tracking,
not just logging.

Training a model without experiment tracking means decisions about hyperparameters, data splits, and architecture changes get made from memory and scattered notebook outputs. Weights & Biases captures every run's configuration and results in one place, so comparing approaches is a real comparison, not a reconstruction effort.

We treat this as standard practice for any project involving model training or fine-tuning, the same way we'd treat version control as standard for code.

How we build it

Reproducible,
not just logged.

Tracking that's actually useful later, not just a record nobody revisits.

01Full run configuration capture

Hyperparameters, data version, and code version captured per run, so a result can be reproduced, not just remembered.

02Side-by-side comparison

Multiple runs compared on the same metrics, so model selection is evidence-based.

03Tied to deployment decisions

The run that actually ships is the one that won the comparison, with a record of why.

Common questions

Before you
book a call.

The questions we get asked most about Weights & Biases and experiment tracking — answered straight, no sales pitch.

Is this necessary for a single fine-tuning run?

Even a single run benefits from tracked configuration — if the result needs reproducing or explaining later, having the exact setup recorded beats reconstructing it from memory.

Does this slow down experimentation?

It's largely automatic once wired in — logging happens as training runs, not as a separate manual step.

What happens to this data after the project ships?

It stays as a record of why the deployed model was chosen over the alternatives tested — useful if the model needs revisiting later.
