Multimodal Monday 35: Small Models, Modular Vision

Quick Hits (TL;DR)

Small models are closing the gap - A 6B image model matches commercial giants. A 1B OCR model beats larger competitors and paid APIs. VisionRAG uses 6-9x less memory than ColPali while matching performance. You no longer need massive models to get state-of-the-art results.

Vision models become modular components - Microsoft’s framework treats vision models as plug-and-play “eyes” for language models. You can upgrade the vision component without retraining the entire system. This makes AI systems cheaper to improve and easier to maintain.

World models handle real robots - Alibaba’s RynnVLA-002 boosts real-world robot task success by 50%. GigaAI’s GigaWorld-0 trains robots on simulated data that transfers to physical tasks. The simulation-to-reality gap is shrinking fast.

Research Highlights

VisionRAG: 3-Pass Pyramid Indexing for Vision-Enhanced Document Retrieval

Inception AI built an OCR-free document retrieval system that matches ColPali’s performance using 6-9x less memory. The system uses pyramid indexing to extract semantic information at multiple levels, producing only 17-27 compact vectors per page instead of 1024.

Why it matters: Large-scale multimodal search becomes feasible when you can index 40x more documents on the same hardware.

Be My Eyes: Extending Large Language Models to New Modalities

Microsoft and USC researchers built a framework where vision models act as external “eyes” for language models through multi-agent collaboration. You can swap out the vision component without expensive retraining of the full architecture.

Why it matters: Modular AI systems cost less to improve and adapt faster to new capabilities.

E2E-GRec: An End-to-End Joint Training Framework for GNNs and Recommender Systems

TikTok’s framework integrates Graph Neural Networks directly into industrial recommender systems with joint training. This eliminates repeated offline GNN inference and enables true end-to-end optimization.

Why it matters: Graph-based recommendations become practical at scale when inference overhead disappears.

The Image as Its Own Reward: Reinforcement Learning with Adversarial Reward

ByteDance uses the generated image itself as the reward signal through adversarial training. Human evaluators prefer these results over baseline methods 70% of the time in head-to-head comparisons.

Why it matters: This solves the reward hacking problem that prevented RL from improving image quality.

MIRA: Multimodal Iterative Reasoning Agent for Image Editing

IBM’s agent uses iterative reasoning to plan and execute image edits. The system breaks down complex editing tasks into steps and refines results through multiple passes.

Why it matters: Reasoning-based approaches produce more consistent edits than single-pass methods.

HunyuanOCR

Tencent’s 1B parameter vision-language model handles OCR tasks better than commercial APIs and larger models like Qwen3-VL-4B. It achieves state-of-the-art results on OCRBench for models under 3B parameters.

Why it matters: You get better OCR quality while using less compute and paying nothing.

RynnVLA-002

Alibaba’s unified vision-language-action and world model combines robot action generation with environment dynamics prediction. It achieves 97.4% success on LIBERO simulation and boosts real-world LeRobot task performance by 50%.

Why it matters: Robots can learn from simulation and transfer that knowledge to physical tasks.

Trends & Predictions

The Shift to Efficiency

Model efficiency stopped being a nice-to-have. It became the competitive advantage.

VisionRAG proves this. Instead of generating 1024 vectors per page like ColPali, it uses pyramid indexing to create 17-27 vectors. Same performance. 6-9x less memory. You can index 40 times more content on the same hardware. This makes large-scale multimodal search practical for companies that couldn’t afford it before.

Z-Image proves it again. This 6B model competes with commercial systems that cost money and use far more parameters. Alibaba didn’t optimize for bigger. They optimized for smarter architecture and better training methods.

HunyuanOCR makes the same point. Just 1B parameters. Beats larger models. Beats commercial APIs. Runs on devices, not data centers.

Modular AI Systems

Microsoft’s “Be My Eyes” framework changes how we build multimodal systems. Vision models become plug-and-play components. You swap them out without retraining the entire architecture.

This matters because retraining joint vision-language models costs millions. Modular systems cut that cost to zero. You upgrade individual components as better versions release. Your system improves faster and cheaper.

This pattern will spread. We’ll see modular audio components, modular video understanding, modular reasoning modules. AI systems will look less like monolithic models and more like composable toolchains.
