What is multimodal AI? Definition and business implications
A multimodal AI model is a model capable of processing and producing several types of content simultaneously: text, image, audio, video, code. The same model can analyse a photo, understand a voice query, read a document, and reply in writing, without any intermediate pipeline.
Historically, AI models were specialised by modality: one model for text, another for image, another for speech. When an application had to combine these modalities (analyse a textual screenshot, for example), it chained several models through an application pipeline, with handoffs costly in latency and information loss. Recent multimodal models (GPT-4o, Claude 4, Gemini) integrate these capabilities natively. The model receives as input a mix of modalities (text plus image, for example) and produces a unified output. The model's internal representation processes text tokens, image regions, and audio segments simultaneously in the same vector space. Practical consequence: a single API call replaces a chain of three to five services, with substantially lower latency and cost, and a finer contextual understanding of mixed content.
Concrete example
An 80-employee accounting firm receives 2,000 supplier invoices every month, a mix of scanned PDFs, screenshots, spreadsheets, and emails. Before multimodal AI, automated processing required a pipeline: OCR (Tesseract), structured extraction, validation (internal workflow), classification (dedicated ML model). With a multimodal model (Claude or GPT-4o), a single API call simultaneously extracts the data, validates its consistency, and identifies anomalies. The operational processing cost falls from about 0.30 euro per invoice to 0.05 euro, and the processing time from 15 minutes to less than a minute per batch.
