Performance Gaps Between 7B and 13B Vision-Language Models in Cross-Domain Object Grounding
Abstract
Abstract: This report synthesises findings from 13 peer-reviewed papers addressing the following research question: Does the performance gap between 7B and 13B VLAs in object grounding persist when evaluated on cross-domain vision-language benchmarks such as LVIS or COCO-Text. We introduce InternVL 2.5, an advanced multimodal large language model (MLLM) series that builds upon InternVL 2.0, maintaining its core model architecture while introducing significant enhancements in training and testing strategies as well as data quality. In this work, we. 0 claims were extracted from source literature; 0 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 3.8/10. This report is a machine-generated literature synthesis and does not constitute original research.
Research Question
Does the performance gap between 7B and 13B VLAs in object grounding persist when evaluated on cross-domain vision-language benchmarks such as LVIS or COCO-Text?
Verification Level
| Paper level | L1, Literature synthesis | |
| Source-grounded claims | 0 | |
| Claim record source | not publicly specified |
Descriptive public verification status only; aggregate claim counts are public, but individual claim records are not exposed here.
Truth-Engine Gate Verdict
| Status | Unverified | |
| Gate | Gate 2 — Verification (formal proof or sandbox reproduction) | |
| Reason | Published before the Gate 2 verification pipeline was activated (2026-06-10). No formal proof or sandbox reproduction has been attempted for this record. | |
| Evaluated | 2026-06-10T06:30:49+00:00 |
This record has not completed Gate 2 of the verification pipeline (a type-checked Lean4 proof for mathematical claims, or a sealed-sandbox reproduction for empirical claims). It is a literature synthesis only. VERIFIED requires an attached reproducible artifact (Lean4 proof source, or repro script and results) before this status can be set; it is not derived from review score or claim count.
Quality Tier
| Tier | Quarantine candidate | |
| Basis | Review score is below 5.0; source-level inspection is required before relying on the synthesis. |
Descriptive public triage only; this tier does not alter current publication or DOI behavior.
Quality Dimensions
| Evidence strength | LOW | |
| Uncertainty disclosure | MEDIUM | |
| Reproducibility status | MEDIUM |
Automated triage signals derived from public fields; not human peer review or independent validation.
Correction Record
| Status | CURRENT |
| Correction count | 0 |
| Manifest contract | paper-manifest-v1.1 |
| Correction contract | correction-record-v1 |
Public corrections are additive records. Current status does not claim the synthesis is error-free.
