Building with Multimodal AI

The gap between "multimodal AI exists" and "I built something useful with it" is smaller than it's ever been — you can call a vision-language model, a speech recognizer, or an image generator with an API and a few lines of code. But building well with multimodal AI means knowing what these models can and can't reliably do, how to combine them, and where the pitfalls are. This closing post is the practical one: how to actually build multimodal applications, and where the whole field is heading — toward general, any-to-any models.

Video and Beyond

Video is where multimodal AI gets genuinely hard. It's not just images — it's images over time, plus audio, at a scale that dwarfs a single picture. The temporal dimension adds motion, causality, and continuity that a still frame can't capture, and the sheer data volume strains everything. Video is also the frontier where the most impressive recent generation results have appeared, and where multimodal AI is actively pushing forward. Understanding video — and the other modalities beyond the core ones — shows where the field is heading.

Audio and Speech

Sound is the modality that makes AI conversational — the difference between typing to a machine and talking to it. And the same architectural ideas that transformed text and vision transformed audio too: treat the waveform as a sequence, train at scale, and one model can transcribe speech across languages, or synthesize a natural-sounding voice from text. Understanding how AI handles audio — recognition, synthesis, and understanding — completes the picture of the core modalities and shows how general the multimodal recipe has become.

Generating Images

Typing a sentence and watching a detailed, coherent, never-before-seen image appear is one of the most striking capabilities in modern AI — and the technique behind it is beautifully counterintuitive. Rather than paint an image stroke by stroke, these models start with pure noise and gradually remove it, step by step, sculpting a picture out of static, guided by your text. Understanding diffusion — and how text steers it — demystifies text-to-image generation and reveals one of the most important generative techniques in AI.

Vision-Language Models

The multimodal capability people actually experience — uploading a photo and asking a chatbot what's in it, or having it read a screenshot, explain a diagram, or extract data from a chart — comes from vision-language models: LLMs that can see. The clever part is how it's done. Rather than build a seeing-and-reasoning model from scratch, you take a language model that already reasons brilliantly and give it eyes, by connecting a vision encoder to it. Understanding how that connection works explains the multimodal AI most people use.

Connecting Modalities: CLIP and Shared Embedding Spaces

The magic trick at the heart of modern multimodal AI is deceptively simple: train an image encoder and a text encoder together so that a picture of a dog and the words "a photo of a dog" land at the same spot in a shared space. Once images and text live in one common representational space, a cascade of capabilities follows — searching images by text, classifying without task-specific training, and grounding language generation in vision. CLIP is the model that made this idea famous, and understanding it is understanding how modalities actually get connected.

How Models See

To a computer, an image is just a grid of numbers — millions of pixel values with no inherent meaning. Turning that raw grid into something a model can understand (this is a dog, that's a face, here's text on a sign) is the problem of computer vision, and the way it's solved has changed dramatically. The field moved from hand-crafted feature detectors, to convolutional networks that learn features, to — most recently — the surprising discovery that the transformer architecture behind language models works remarkably well for images too. Understanding how models see is the foundation of the vision side of multimodal AI.

What Multimodal AI Is

For most of the deep-learning era, an AI model did one thing with one kind of data: this model classifies images, that one translates text, another transcribes speech. Multimodal AI breaks that separation. A single model can now look at an image and describe it, answer questions about a chart, generate a picture from a sentence, or transcribe and reason about audio — because it works across modalities rather than being confined to one. This shift, from single-modality specialists to models that bridge vision, language, audio, and more, is one of the most important developments in modern AI.
