The multi-crop era of open MLLMs: AnyRes-style schemes with per-model hyperparameter tuning

gabriberton · x · 2026-10-19

Most open MLLMs in 2024-2025 used multiple crops per image (LLaVA-NeXT, InternVL, Gemma 3, Molmo), in forms like AnyRes, Pan&Scan, and overlapping crops — all broadly similar.

The cost: higher complexity and per-model hyperparameter tuning (crop count, resolution, overlap). The attached LLaVA-1.5 report figure illustrates the AnyRes dynamic high-resolution scheme with a 2×2 grid, encoding crops and a resized thumbnail before flattening into the LLM.
