Multimodal Progress: From Concept to Frontier Models

How did AI go from reading text to seeing images, hearing audio, and reasoning across modalities at once? This path traces the arc — from the core idea of vision-language models, through the ecosystems and labs pushing the frontier, to the specific models where multimodal capability has landed today. Starts with the concept, ends with the cutting edge.

  1. Vision-Language Models

    Start here: this is the foundational concept — what vision-language models are and why combining sight and language is the core challenge of multimodal AI.

  3. OpenAI

    OpenAI's multimodal releases — from DALL·E to GPT-4V — set many of the benchmarks the field now races against.

  4. Google DeepMind

    Google DeepMind's Gemini line represents the other major multimodal bet — a different architectural philosophy worth comparing directly to OpenAI's approach.

  5. Mixture of Experts

    Mixture-of-Experts is the architectural technique powering several frontier multimodal models — knowing it explains how labs scale capability without proportionally scaling cost.

  6. GPT-5.5

    GPT-5.5 is a concrete example of where OpenAI's multimodal ambitions have arrived — the ideas from earlier steps, shipped.
