Frequently asked questions
What is Fine-tuning platforms?
Products for adapting a base model with your data, not the base model sale. Jobs: supervised fine-tunes; preference tuning; adapter training.
What should not be listed as Fine-tuning platforms?
Products whose buyer job is full training from scratch, hosting-only, or prompt-management tools. Those belong on their own category page so search queries are not split.
Has AI Trustmark independently assessed every Fine-tuning platforms supplier?
No. A category listing is descriptive. Independent assessment is shown only on company or product pages that carry Trustmark evidence.
What are Fine-tuning platforms?
Products for adapting a base model with your data, not the base model sale. Jobs: supervised fine-tunes; preference tuning; adapter training.
What model or provider changes should a buyer insist on being told about?
Material change usually includes a new model family, new region, new subprocessor, new write-capable tool, or a change that affects logging, privacy or human oversight. Those changes should trigger evidence refresh rather than a silent release.
How should buyers verify where AI customer data is processed?
Ask for the named processing locations, cloud regions and any subprocessors that see prompts, files or outputs. A directory listing is not evidence of residency. Independent assessment records the locations that were in scope on the assessment date.
Does a TrustMark on one product cover the rest of the company?
No. Independent assessment is scoped to the named organisation and, where relevant, the named product. Category pages list suppliers as a topic label. They do not imply that every listed company has been assessed.
What incident-handling evidence is useful for AI suppliers?
Buyers should see how AI-specific failures are detected, contained and notified — including unsafe outputs, data leakage and unauthorised agent actions. An incident policy that never mentions models, prompts or tools is incomplete for this class of product.
