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.

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.
Reproducible,
not just logged.
Tracking that's actually useful later, not just a record nobody revisits.
Hyperparameters, data version, and code version captured per run, so a result can be reproduced, not just remembered.
Multiple runs compared on the same metrics, so model selection is evidence-based.
The run that actually ships is the one that won the comparison, with a record of why.
Where this fits
The tracking layer underneath any fine-tuning or training work we do.
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.
