Anthropic's Powerful Opus 4.1 Model Is Here - How to Access It (and Why You'll Want To)

Anthropic released Claude Opus 4.1 on Tuesday, upgrading its flagship AI model for agentic tasks, coding, and reasoning across platforms.
This release follows the May debut of Claude Opus 4 and aims to maintain leadership amid upcoming OpenAI GPT-5 announcements expected in days.
Claude 4.1 improved coding accuracy to 74.5% on SWE-bench Verified, outperforming OpenAI's 69.1% and Google's 67.2%, with strengths in complex code refactoring.
The model offers hybrid reasoning balancing quick responses and deep problem-solving, expanded context handling up to 32,000 tokens, and powers tools like Claude Code and APIs.
Anthropic's rapid growth faces risks from high revenue concentration among two customers and stiff competition, but further model improvements are planned in the coming weeks.
