[wandb.ai](https://wandb.ai) "is for experiment tracking and metric visualization". As observed in ([Wang et al. 2025](https://arxiv.org/abs/2506.21734))'s [github repo](https://github.com/sapientinc/HRM) (Sapient Intelligence, Singapore).

Important things to note from this:

- #llmops -- traces, evaluations, playground, agents, guardrails, monitors.
- #mlops -- experiments, sweeps (optimizing hyperparams), tables (explore and visualize data)
- platform features -- explore hosted, OSS models, model & data registry, artifacts, reports, SDK, automations. (nb. a lot of this sounds like [huggingface](https://shared.btbytes.com/p/huggingface)).
