Claude Sonnet 5 Launches, Disrupting AI Market

The market for AI models is becoming increasingly competitive. As of July 2026, Anthropic’s Claude Sonnet 5 has launched as a high-performance, cost-efficient model designed specifically to make "agentic" tasks viable for enterprise budgets. Meanwhile, ChatGPT’s market share has seen a decline below 50% as users diversify their usage across multiple models like Claude and Gemini.
