Anthropic's AI chatbot Claude has been gaining significant attention and traction in recent months, posing a growing challenge to OpenAI's ChatGPT. Launched in 2023, Claude is part of Anthropic's family of leading AI models and has expanded beyond its initial core audience of software engineers to target a wider range of enterprise applications. The competition between Anthropic and OpenAI has intensified, with both companies vying for market share and partnerships, including with the Pentagon.

Why it matters

The rivalry between Claude and ChatGPT highlights the rapidly evolving landscape of generative AI, with major tech companies competing to develop the most capable and versatile language models. The success of Claude could have significant implications for the AI industry, potentially disrupting the dominance of OpenAI and other established players. Additionally, Anthropic's stance on limiting military access to its AI models has sparked a debate around the ethical use of this technology.

The details

Anthropic launched Claude in March 2023, several months after OpenAI released ChatGPT. Anthropic initially delayed the release of Claude due to concerns about sparking an AI arms race, instead focusing on enterprise applications. In early 2026, Anthropic expanded Claude's capabilities beyond its core audience of software engineers, releasing the Cowork tool to make the AI more user-friendly for non-programming tasks. This move, along with Anthropic's refusal to grant the Pentagon unfettered access to its AI models, has helped drive increased usage and attention for Claude.

  • Anthropic launched Claude in March 2023.
  • Anthropic made Claude available to the general public in July 2023.
  • In February 2026, Anthropic released Opus 4.6, an upgrade to a model that scored higher than any human candidate on Anthropic's engineering test.
  • Anthropic released the Cowork tool in January 2026, aimed at making Claude more accessible for non-programming tasks.
  • In March 2026, Anthropic announced it was bringing voice mode to Claude Code.
