Multimodal Monday #34: Visuals Coherence, Semantic Vision

📢 Quick Hits (TL;DR)

Complex visuals and visualizations that actually work - Nano Banana Pro generates professional infographics where text, diagrams, and relationships all work correctly. Ask for detailed scientific diagrams or technical schematics with multiple text elements and get publication-ready output, not artistic gibberish.

Segmentation by concept, not description - SAM 3 understands what you mean, not just what you describe. Point at something and say "the concept behind this interaction" and it detects, segments, and tracks objects across images and video using ideas instead of visual features.

Neural retrieval meets classical search - Microsoft's Weighted Chamfer adds BM25-style token weighting to ColBERT's multi-vector retrieval. Some words matter more than others when you search, and this simple addition boosts performance without architectural changes.

🧠 Research Highlights

Mixture of States: Routing Token-Level Dynamics for Multimodal Generation

Meta routes different tokens through different processing pathways in their Mixture of States architecture. This routing mechanism improves output quality and diversity in their SAM 3 model.

Why it matters: Token-level routing gives models more flexibility to handle different types of content within a single generation.

Incorporating Token Importance in Multi-Vector Retrieval

Microsoft's Weighted Chamfer enhances ColBERT by weighting tokens based on their importance, similar to BM25's term weighting. The method improves retrieval performance without adding computational overhead.

Why it matters: You get better search results by recognizing that not all tokens contribute equally to meaning.

🛠️ Tools, Models and Techniques

Gemini 3 and Nano Banana Pro

Gemini 3 is Google's universal translator, accepting any input type and outputting whatever format your task demands. Nano Banana Pro is where complex visualization generation finally works: Request infographics about quantum computing, DNA replication, financial market dynamics, or engineering systems and receive coherent professional output. Text reads correctly. Diagrams connect logically. Mathematical notation renders properly. The model understands what should be emphasized, how elements relate, and what makes a visualization useful versus decorative.

Why it matters: The pipeline: Gemini 3 for concept development → Nano Banana Pro for visualization → Veo 3.1 for animation, replaces weeks of specialized work with minutes of prompting. Teachers generate custom diagrams for every concept. Journalists create data visualizations in real-time. Anyone with domain knowledge can produce professional visual content.

SAM 3 and SAM 3D

Meta's SAM 3 detects, segments, and tracks objects across images and videos using conceptual prompts. SAM 3D extends this to 3D human mesh recovery.

Why it matters: You can now identify and track objects by describing concepts, not just visual features.

📈 Trends & Predictions

When Text in Images Actually Reads Right

Image generators have struggled with text for years. You'd get something that looked decent from across the room. Zoom in and the letters dissolved into gibberish. Numbers made no sense. Diagrams contradicted themselves. This kept generative AI locked into artistic images and simple graphics.

Nano Banana Pro changes this. The model generates infographics with multiple text elements at different sizes, all readable. Diagrams connect logically. Structured visualizations communicate information instead of just looking busy.

The model understands relationships between elements. A chart's title corresponds to its data. Labels point to the right things. Text hierarchy makes sense. This wasn't possible before. Here's what you can do now. Use Gemini 3 to draft your visualization concept. Feed that to Nano Banana Pro for generation. Take the output to Veo 3.1 for animation. You go from idea to polished explainer video in minutes.

Build applications that generate custom visualizations on demand. Create dynamic infographics that adapt to user queries. Produce visual content at scale without hiring designers. The workflow becomes: describe what you need, get a professional result. Education changes when teachers generate custom diagrams for every concept. Journalism shifts when reporters create data visualizations in real time. Marketing teams produce hundreds of variants to test messaging. Anyone with an idea can create professional visual content.

The technical barrier vanished. You don't need design skills anymore. You need clear thinking about what information matters and how to present it. The model handles execution.

Retrieval Learns From Search's Old Tricks

ColBERT represented a leap in retrieval technology by encoding queries and documents as multiple vectors instead of single embeddings. This captured more nuanced meaning. But it treated every token equally, which doesn't match how language works. Microsoft's Weighted Chamfer borrows from BM25, the search algorithm that dominated information retrieval for decades. BM25 recognized that "algorithm" matters more than "the" when you search. Weighted Chamfer applies this insight to ColBERT's multi-vector approach. The implementation is straightforward. Weight tokens based on their importance to meaning. "Quantum computing applications" gets different weights for each word. "Applications" and "quantum" score high. "Computing" matters less because it's implied. The model learns these weights from data.

This simple addition improves retrieval performance measurably. You get better results without redesigning the architecture or adding computational overhead. The insight: newer isn't always better. Sometimes you take what worked in older systems and apply it to new approaches.

The pattern repeats across AI development. Attention mechanisms borrowed from neuroscience. Residual connections came from signal processing. Batch normalization adapted techniques from statistics. Progress comes from combining proven ideas in new contexts, not just inventing from scratch.For your retrieval systems, this means looking at what worked before neural networks. Term weighting, document frequency, position encoding. These concepts still matter. Modern architectures give you new ways to implement old wisdom.

GraphRAG takes this further by adding structure to retrieval. Instead of treating documents as flat text, map relationships between concepts. When someone asks a complex question, traverse the graph to gather connected information. Multi-hop reasoning becomes possible because you encoded how ideas relate.

The combination of weighted tokens and graph structure gives you retrieval systems that handle complex queries. You can answer "How does X affect Y, and what are the implications for Z?" by following edges through your knowledge graph, weighting information by relevance as you go.
