LLM & Foundation Models

Large Language Models and foundation model providers shaping the AI landscape

Overview

Large Language Models (LLMs) and foundation models are pre-trained AI systems capable of understanding and generating text, code, images, and other modalities. They have become the core building blocks of modern AI applications.

Market Size

The generative AI market (including LLMs) is projected to exceed $60 billion by 2025, with the broader AI market reaching $300+ billion.
