## Tools (as reported by the server, not verified)

- `vram\_fit`: Will this LoRA config train on a card with vram\_gb GB? Returns verdict fits / tight / does\_not\_fit, the predicted peak in MB, the margin, how each part was derived, and any measured probe with the same settings.
- `vram\_max\_rank`: Largest LoRA rank \(multiple of 8\) that fits with margin on a card with vram\_gb GB, and the largest that is tight \(a real run may fit, the one-step probe would not\).
- `vram\_probes`: The raw measured probe rows \(RX 7900 XTX and RTX 3060 Ti\), filtered by any of the given settings. gpu matches part of the card name, e.g. '7900' or '3060'.
