The Market of specialized AI explodes: $320 billion investment and up to 800% ROI for companies that choose the right strategy.
Small Language Models market explodes: from $6.5 billion in 2024 to over $29 billion by 2032, offering higher ROIs and lower costs than giant models.
In 2025, as media attention focuses on expensive Large Language Models such as GPT-4 and Claude, a more pragmatic revolution is transforming the business landscape: small language models (SLMs) are generating concrete and sustainable returns for companies that focus on efficiency and specialization.
The Context: When Bigger Doesn't Mean Better
Large Language Models have demonstrated extraordinary capabilities, with billion-dollar investments such as the $14.3 billion Meta-Scale AI deal. However, for most business applications, these giants represent an expensive and difficult overkill.
Small Language Models, with parameters ranging from 500 million to 20 billion, offer a more sustainable and often better performing alternative on specific tasks.
