Anthropic introduced Claude Opus 4 and Claude Sonnet 4 on 22 May 2025, positioning the release around sustained coding performance, reasoning and agentic workflows.
The company also announced Claude Code general availability and new developer-facing capabilities, including a code execution tool, MCP connector, Files API and longer prompt caching.
The launch showed how frontier-model competition was moving toward tool use and software work. The question for buyers was less which chatbot answered a prompt best and more which system could operate reliably inside real engineering and business processes.
Why It Matters
Claude 4 made coding agents and long-running software tasks a central competitive battleground for frontier AI vendors.
What to Watch
Watch enterprise adoption of coding agents, safety controls around tool execution, and whether model vendors can turn benchmark gains into dependable workflow automation.
