Open-weight model
Open-weight model is a model whose trained parameters are released for self-hosting and adaptation. For open-weight model, the useful boundary is the data it uses, the tools it can call, the approvals it needs, the review standard, and the finance decision it may influence before the output is trusted or automated.
Also known as open-weights model, open-source LLM, open model
Why it matters
Understanding open-weight model matters because AI-assisted finance work can sound confident even when data, assumptions, or compute paths are wrong. A useful definition keeps the output grounded, reviewable, and accountable. Pluvo's model-agnostic design works across open-weight and proprietary models, keeping your finance context and computed numbers in Pluvo regardless of provider.
In practice
Governance example
Teams use open-weight model when they evaluate whether an AI-assisted analysis can be trusted. The useful test is whether the output is tied to approved data, repeatable logic, human review, and an audit trail.

Pluvo's model-agnostic design works across open-weight and proprietary models, keeping your finance context and computed numbers in Pluvo regardless of provider.
In practice, teams should define open-weight model with a clear source, owner, time period, and decision before they use it in reporting, planning, or operating reviews.

A strong workflow for open-weight model separates the definition from the action: first agree what the term means, then decide how it is measured, when it changes, and who is accountable for the next step.

FAQ
What is an open-weight model?
Open-weight model is a model whose trained parameters are released for self-hosting and adaptation. For open-weight model, the useful boundary is the data it uses, the tools it can call, the approvals it needs, the review standard, and the finance decision it may influence before the output is trusted or automated.
What is the difference between open-weight and open-source models?
The boundary for open-weight model differs from related terms by scope, source data, time period, and decision use. In this glossary, it covers what an open-weight model is — a model whose trained parameters are released for self-hosting and adaptation — versus closed, API-only models, so teams should compare those boundaries before using it in reporting or planning.
