May 16, 2024

Large language models are pre-trained on large datasets and use natural language processing to perform linguistic tasks such as text generation, code completion, paraphrasing, and more.

The initial release of ChatGPT sparked the rapid adoption of generative AI, which has led to large language model innovations and industry growth.

In fact, 92% of Fortune 500 firms have started using generative AI in their workflows.

As adoption continues to grow, so does the LLM industry. The global large language model market is projected to grow from $6.5 billion in 2024 to $140.8 billion by 2033.
