Everyone knows OpenAI because of GPT. In 2026, it is still the leader in making AI that can talk, write, and create just like a human. This Sam-Altman-led startup moved past simple chat quickly. It has now become the face of Generative AI apps.
Anthropic is the company for people who worry about AI going off the rails and turning into a human-killing machine. The California-based firm builds ethical large language models for big businesses. Its focus is on safety, making sure the AI stays helpful and shows transparency, decreasing the chances of AI hallucinations.
