## What the story says

Shell's NLP research team uses Weights & Biases to log experiments, build custom dashboards, run hyperparameter sweeps, and track evaluations and user feedback while adapting large language models to its internal technical reports. The resulting models power a research assistant that acts as an institutional memory for researchers.

Summary written by usedby from the source page, in English. The figures are those of Weights & Biases and Shell, not ours.

> At the core of this scalable infrastructure is Weights & Biases, which plays critical roles in supporting experiment tracking and logging, building custom dashboards for increased visibility into training dynamics, robust hyperparameter optimization, and evaluation and feedback through both W&B Models and W&B Weave.

- **26%**: “The DAPT + instruction-tuning models led to a 26% increase in accuracy compared to non-fine-tuned Llama models, and a 30% improvement in domain-specific understanding on Shell benchmarks.”

> We built a custom dashboard using Weights & Biases for all our experiment logging, and a lot of critical hyperparameter tuning using W&B Sweeps to explore impact and sensitivity.
