An OCR-style question for LFM2.5-VL-3B needs source-grounded acceptance, because a persuasive visual explanation can differ from an accurate reading of the image.

## Reading and explaining are different outputs

A model can produce a coherent description while getting a decisive character wrong. If an application needs a literal field, that description is not an equivalent substitute. The acceptance rule must identify whether the task asks for transcription, interpretation or a decision based on the transcribed content.

## The release in context

The [visual-model announcement](https://www.liquid.ai/blog/lfm2-5-vl-3b) introduces the relevant image path. The earlier [hybrid release](https://www.liquid.ai/blog/lfm2-5-8b-a1b) and [compact release](https://www.liquid.ai/blog/lfm2-5-230m) establish preceding family context. They do not prove that every OCR-like application is certified by the visual release or that a broad model evaluation covers a particular document layout.

The historical change is access to another visual-language artifact. Its usefulness for document work remains a concrete task question. A family-level capability description should guide investigation rather than replace a fixture that represents the source material the application actually receives.

## A document-table example

Imagine a photographed table with similar values in adjacent rows. The answer may copy a value accurately but associate it with the wrong item. A transcription-only check can miss that error, while a broad explanation can make the mistaken association sound plausible.

| Required property | Evidence to preserve |
| --- | --- |
| Literal text | The relevant source region and extracted field. |
| Row association | The item named by the question and its linked value. |
| Interpretation | The rule applied after the source field was identified. |

## Do not invent missing content

An unreadable field creates an evidence limit. Supplying a plausible completion can make a workflow appear successful while removing the distinction between observed and inferred material. A useful application should preserve that distinction even when its interface prefers a filled field over an unresolved status.

Retain the source region alongside the output so that review can determine what was actually visible. If image preparation removed the field, the correction belongs earlier in the path. If the field was visible but misread, the task evaluation should identify that specific failure.

## The retrospective lesson

The release creates an opportunity for source-backed visual work, not a license to treat generated prose as the source itself. Ordinary task acceptance remains necessary even when the answer is fluent and the model correctly identifies the document's general topic.

The conclusion is to evaluate the smallest consequential claim against the image. Distinguishing transcription, association and interpretation makes both success and failure more explainable than an undifferentiated judgment that the visual answer looks convincing.
